UTI Alert: Bathroom Habits Doctors Say Are Germ Magnets

1. Not Wiping Front to Back

One of the most critical bathroom habits for preventing UTIs is the direction in which you wipe after using the toilet. Wiping from back to front can inadvertently introduce harmful bacteria—most notably Escherichia coli (E. coli)—from the anus to the urethra. Since the urethra is the entry point to the urinary tract, even a small transfer of bacteria can quickly lead to infection. Women are especially at risk because their urethra is shorter and located closer to the anus, making it easier for bacteria to travel and cause problems.

Doctors universally advise wiping front to back as the gold standard for hygiene. This method ensures that bacteria are always swept away from the sensitive urinary and vaginal areas, greatly reducing the risk of cross-contamination. The Centers for Disease Control and Prevention (CDC) specifically lists front-to-back wiping as a key preventive measure for UTIs.

Adopting this simple yet effective habit can make a significant difference in your urinary health. Parents and caregivers should also teach young children to practice this from an early age, as proper technique can help prevent recurring infections and long-term complications.

2. Holding in Urine Too Long

Many people are guilty of ignoring the urge to urinate, whether it’s during a marathon work meeting, a long commute, or when simply too busy to take a break. However, consistently holding in urine provides bacteria with the perfect environment to multiply inside the bladder. When urine sits for extended periods, bacteria have more time to grow and potentially invade the urinary tract, increasing the risk of infection.

This risk is particularly high for those with hectic schedules who may go several hours without visiting the restroom. According to the Urology Care Foundation, delaying urination can also irritate the bladder lining, making it more susceptible to infection and discomfort.

Doctors recommend listening to your body’s signals and scheduling regular bathroom breaks throughout the day, even if you don’t feel an urgent need. Establishing a routine—such as going every three to four hours—can flush bacteria out of your system and maintain a healthier urinary tract. Incorporating this habit is a simple yet crucial step in safeguarding yourself from unnecessary infections.

3. Skipping Post-Sex Urination

Sexual activity is a well-known factor that can contribute to urinary tract infections. The friction and contact involved can introduce bacteria from the genital and anal areas toward the urethra, especially in women. In fact, studies have shown that postcoital UTIs are common, with up to 80% of recurrent UTIs in sexually active women occurring within 24 hours after intercourse, according to research published in the Journal of Clinical Medicine.

Skipping urination after sex allows bacteria to linger in the urethra, giving them more time to travel up into the bladder and cause infection. Urinating promptly after sexual activity helps flush away any bacteria that may have been introduced during intercourse, reducing the risk of infection significantly.

Doctors recommend making post-sex urination a consistent habit for both women and men. It’s a simple step that takes only a few moments but can have a profound effect on your urinary health. For those especially prone to UTIs, this practice, combined with good genital hygiene, can be a crucial line of defense.

4. Using Scented Wipes or Sprays

Many people turn to scented wipes or feminine sprays hoping to feel fresher, but these products often do more harm than good. The chemicals and artificial fragrances in scented wipes and sprays can disrupt the natural balance of good bacteria, or flora, that protect the delicate skin around the urethra and vagina. When these protective microbes are disturbed, harmful bacteria can thrive, increasing the risk of irritation and infection.

Unscented products, on the other hand, are formulated to be much gentler. According to the American Academy of Dermatology, fragrance is one of the most common causes of allergic reactions and irritation in sensitive areas. Using scented wipes or sprays can also lead to dryness and inflammation, which further compromise the body’s natural defenses against UTIs.

Doctors recommend choosing fragrance-free and hypoallergenic products for personal hygiene. If you feel the need for extra cleansing, plain warm water or specially formulated unscented wipes are the best options. By making this simple switch, you help preserve your body’s natural protective barriers and reduce your risk of urinary tract infections.

5. Not Washing Hands Before and After

It’s easy to underestimate just how many germs are lurking on your hands—especially before and after using the bathroom. Touching your genitals with unwashed hands can transfer bacteria directly to sensitive areas, setting the stage for infections like UTIs. Likewise, skipping handwashing afterward can spread those germs to surfaces and other people, amplifying the risk.

The Centers for Disease Control and Prevention (CDC) stresses the importance of thorough handwashing as one of the most effective ways to prevent the spread of infection. Their guidelines recommend scrubbing hands with soap and water for at least 20 seconds, making sure to clean under fingernails and between fingers.

To build a strong defense against bacteria, always wash your hands both before and after using the toilet. This habit is especially crucial if you’re prone to UTIs or caring for someone who is. If soap and water aren’t available, an alcohol-based hand sanitizer is a good backup, but never a complete substitute for proper washing. A small investment of time at the sink can go a long way in protecting your urinary health.

6. Sharing Towels

Sharing towels may seem harmless, especially among family members or close friends, but it can be a hidden source of bacterial transfer. Damp towels provide an ideal environment for bacteria and fungi to thrive, allowing microbes from one person’s skin or genitals to easily spread to another. This is particularly concerning when it comes to bacteria that can cause UTIs or other infections.

Just as you wouldn’t share a toothbrush, doctors advise against sharing towels or other personal hygiene items. The CDC warns that bacteria and even viruses can linger on fabrics for hours or days, increasing the risk of cross-contamination. Shared towels are especially problematic if someone in the household has a current or recent infection.

The best practice is to assign individual towels for each person and launder them regularly in hot water. This simple measure drastically reduces your risk of picking up someone else’s germs. Whether at home, the gym, or while traveling, using your own clean towel is a small act of self-care that can help protect your urinary health and overall well-being.

7. Ignoring Toilet Cleanliness

Toilets are a breeding ground for a wide range of microbes, including Escherichia coli, Staphylococcus, and various viruses. These germs can linger on toilet seats, flush handles, and even surrounding surfaces. While public toilets are often thought to be dirtier, studies suggest that even home toilets can harbor significant bacterial loads if not cleaned regularly. In fact, a neglected home toilet can sometimes contain more bacteria than a well-maintained public restroom.

The CDC emphasizes the importance of routine cleaning to prevent the spread of infection. Microbes can survive on hard surfaces for hours or days, and simply flushing the toilet can send a spray of bacteria into the air, contaminating nearby items and surfaces.

To safeguard your urinary tract and overall health, make it a habit to clean toilets thoroughly at least once a week using disinfectants. Wipe down not only the seat but also the flush handle and any frequently touched surfaces. Keeping your bathroom sanitary is a simple yet powerful step in minimizing your exposure to harmful germs and reducing your risk of UTIs.

8. Flushing With the Lid Up

Flushing the toilet with the lid up may seem harmless, but it can actually propel a cloud of aerosolized germs into the air—a phenomenon known as “toilet plume.” When you flush, water turbulence can send tiny droplets containing bacteria and viruses onto nearby surfaces, including toilet seats, handles, sinks, and even toothbrushes. Studies, such as those published in the Journal of Hospital Infection, have shown that microbes like norovirus and E. coli are easily dispersed during flushing and can remain viable for hours.

This invisible spray increases the risk of contact with harmful bacteria, especially in shared or small bathrooms. Over time, these germs can accumulate, raising the likelihood of infections like UTIs and gastrointestinal illnesses.

Doctors recommend always closing the toilet lid before you flush. This simple action drastically reduces the spread of bacteria and keeps your bathroom surfaces cleaner. If you’re in a public restroom without lids, be extra diligent about hand hygiene and avoid placing personal items near the toilet. Adopting this habit is an easy yet effective way to minimize your exposure to unwanted germs.

9. Sitting on Damp Toilet Seats

Moisture is a key factor in helping bacteria and other microbes survive and multiply on surfaces—including toilet seats. In public restrooms, damp seats are often the result of recent cleaning, splashes, or, unfortunately, poor hygiene from previous users. This lingering moisture creates a welcoming environment for germs such as E. coli and Staphylococcus, which can persist for hours on wet surfaces. The risk increases when the skin around your thighs or genitals comes into direct contact with these microbes.

According to the CDC, bacteria thrive in warm, moist environments, making a damp toilet seat a prime spot for contamination. Although the odds of contracting an infection from a toilet seat are low, the risk is not zero—especially for those with compromised immune systems or existing skin abrasions.

Whenever you encounter a damp seat, wipe it down thoroughly with toilet paper before sitting, or opt for a disposable seat cover if available. In a pinch, layering toilet paper can provide a modest barrier. By taking these precautions, you minimize direct exposure to lingering germs and reduce your risk of infection.

10. Wearing Non-Breathable Underwear

Your choice of underwear plays a surprisingly important role in urinary tract health. Synthetic fabrics like polyester, nylon, or spandex trap heat and moisture against the skin, creating a warm, damp environment where bacteria and yeast can thrive. This increased moisture not only leads to discomfort but also raises the risk of irritation and potential infection, including UTIs.

In contrast, natural fibers such as cotton allow air to circulate freely and wick moisture away from the body. The American Academy of Dermatology recommends choosing breathable cotton underwear, especially for those prone to infections or sensitive skin. Cotton’s absorbent and airy properties help keep the genital area dry, making it harder for bacteria to proliferate.

Doctors advise replacing non-breathable underwear with 100% cotton or other moisture-wicking, breathable fabrics. Change out of damp clothes promptly after exercise or swimming, and avoid tight-fitting underwear that can further restrict airflow. This small, daily habit can have a big impact on your comfort and urinary tract health, helping you stay fresh and infection-free.

11. Frequently Using Bubble Baths

Indulging in a fragrant bubble bath can be relaxing, but frequent use of bath additives poses hidden risks to urinary health. Many bubble baths, bath bombs, and scented bath oils contain chemicals and fragrances that disrupt the natural pH balance and healthy flora of the genital area. This disruption makes it easier for harmful bacteria to gain a foothold, increasing the risk of irritation and UTIs.

Compared to showers, which rinse the body and genital area with fresh water, soaking in a bath allows these additives to linger on the skin and around the urethra. According to the NHS, bubble baths and similar products are a common cause of recurrent UTIs, particularly in children and those with sensitive skin.

To protect your urinary tract, limit bubble bath use and opt for plain, unscented bath products if you choose to soak. Showers are generally a safer choice for everyday hygiene, as they minimize prolonged exposure to potentially irritating substances. By making this small change, you can enjoy relaxation without compromising your health.

12. Reusing Unwashed Washcloths

Damp washcloths left hanging in the bathroom can quickly become breeding grounds for bacteria and mold. When you reuse an unwashed washcloth, you risk transferring these microbes back onto your skin, including sensitive areas near the urinary tract. Bacteria such as Staphylococcus aureus and E. coli thrive in moist, warm environments, making an unwashed cloth a perfect host.

Many people wash their washcloths only once a week or less, but this is far from ideal. According to the CDC, items like towels and washcloths should be laundered frequently to prevent the buildup of harmful germs. Daily washing is especially important if the cloth is used for intimate hygiene or after workouts.

To minimize your risk of infection, use a fresh, clean washcloth each day and launder used ones in hot water. Avoid sharing cloths with others, and ensure they dry thoroughly between uses. By adopting this routine, you help maintain a healthier bathroom environment—and a lower risk of UTIs.

13. Using Harsh Soaps on Genitals

The skin around the genitals is far more sensitive than most other parts of the body, and using harsh soaps or cleansers can do more harm than good. Many regular soaps contain strong detergents and fragrances that strip away natural oils and disrupt the delicate pH balance of the genital area. This can lead to dryness, irritation, and a weakened barrier that makes it easier for bacteria to cause infections like UTIs.

American Academy of Dermatology recommends choosing mild, fragrance-free options or simply using warm water for daily cleansing.

For optimal hygiene, avoid regular bar soaps and aggressive body washes on sensitive skin. Instead, opt for gentle, pH-balanced products—or skip soap altogether and use plain water. This approach helps preserve the natural flora and keeps your genital area healthy and comfortable, reducing your risk of irritation and urinary tract infections.

14. Overusing Antibacterial Products

While antibacterial soaps and wipes may seem like the ultimate defense against germs, overusing these products can actually backfire. Excessive use of antibacterial agents can disrupt the natural microbiome—the community of beneficial bacteria that live on your skin and help protect against harmful invaders. When these good microbes are killed off, it can leave your skin and mucous membranes more vulnerable to infection, including UTIs.

Moreover, the widespread use of antibacterials contributes to the development of antibiotic-resistant bacteria, a growing public health concern. The CDC advises that routine handwashing with plain soap and water is usually sufficient for maintaining hygiene and preventing infection. Antibacterial products should be reserved for situations where there is a specific need, such as in healthcare settings or when someone in the household is ill.

For most people, moderation is key: use regular soap and water for daily cleaning, and limit antibacterial products to times when they are truly necessary. This approach helps maintain your body’s natural defenses, reduces resistance risk, and supports a healthier urinary tract.

15. Not Changing Pads or Liners Often

Menstrual pads and panty liners are designed to absorb moisture, but they can also become ideal breeding grounds for bacteria if not changed regularly. As these products become damp with blood or discharge, bacteria can multiply quickly, especially in the warm environment of tight clothing. The longer a pad or liner is worn, the greater the risk of irritation, odor, and even infections—including UTIs and vaginal infections.

Health experts, including the NHS, recommend changing pads or liners every 4-6 hours, or more often if flow is heavy. Overnight, it’s best to use a product designed for extended wear and to change it promptly in the morning. Not only does this keep you feeling fresh, but it also minimizes the time bacteria have to grow near the urethra.

To support your urinary and reproductive health, prioritize timely changing of pads and liners. Carry extra products with you when out and about, and choose breathable, unscented options when possible. These simple habits can help prevent discomfort and lower your risk of unwanted infections.

16. Douching Regularly

Douching, or rinsing the vagina with water or other fluids, is often marketed as a way to feel clean—but it can actually do more harm than good. Regular douching disrupts the natural vaginal flora, the balance of healthy bacteria that protect against infections. When this protective barrier is disturbed, harmful bacteria can multiply, leading to an increased risk of UTIs, bacterial vaginosis, and even pelvic inflammatory disease.

The Centers for Disease Control and Prevention (CDC) and most gynecologists strongly advise against douching unless specifically recommended for a medical reason. Research shows that women who douche are more likely to experience recurrent infections and other complications than those who avoid the practice.

Your vagina is self-cleaning and does not require internal rinsing to stay healthy. Skip the douching and focus on gentle, external cleansing with warm water. By respecting your body’s natural defenses, you’ll be better protected against irritation, discomfort, and urinary tract infections.

17. Using Old or Dirty Razors

Old or dirty razors are a hidden danger lurking in many bathrooms. When razors are left damp or reused without proper cleaning, they can become breeding grounds for bacteria, mold, and even rust. Shaving with a contaminated razor can cause tiny nicks or micro-cuts in the skin, providing an easy entry point for bacteria to invade and potentially trigger infections—especially around the sensitive genital area.

Both disposable and reusable razors pose risks if not cared for properly. Disposable razors should be replaced after just a few uses, while reusable ones need to be rinsed thoroughly, dried, and changed regularly. According to the American Academy of Dermatology, razors used on sensitive areas should not be shared and should be replaced at the first sign of dullness or debris buildup.

To minimize your risk of infection, always use a clean, sharp razor and store it in a dry place. Avoid shaving over irritated or broken skin, and follow up with gentle cleansing. By practicing good razor hygiene, you can keep your skin—and urinary tract—healthier and safer.

18. Wearing Wet Swimwear Too Long

After a swim, it’s tempting to lounge in your damp swimsuit—but staying in wet swimwear for extended periods can put your urinary tract at risk. The combination of moisture, warmth, and close-fitting fabric creates an environment where bacteria and yeast can thrive. These microbes may easily migrate to the genital area, increasing the risk of irritation, yeast infections, and UTIs.

Quickly changing out of wet swimwear and into dry clothing makes a significant difference in maintaining urinary and reproductive health. According to the NHS, prolonged dampness around the genital area is a well-known risk factor for infections, especially in women and children.

Doctors recommend always changing into dry underwear and clothes as soon as possible after swimming or exercising. This simple step helps keep the genital area dry and less hospitable to harmful bacteria. If you’re at the beach, pool, or gym, pack a spare set of clothing so you can change quickly and reduce your risk of developing a UTI or other infection.

19. Not Cleaning Sex Toys Properly

Sex toys can be a source of pleasure, but when not cleaned thoroughly, they can also become reservoirs for bacteria, viruses, and yeast. Bodily fluids and microscopic debris can linger on surfaces, providing an ideal environment for microbes to grow. When these toys are reused without proper sanitation, bacteria can be introduced directly to the genital or urinary tract—raising the risk of infections such as UTIs, bacterial vaginosis, or yeast infections.

Proper cleaning protocols are essential to ensure safety. The Planned Parenthood recommends washing sex toys with warm water and mild, fragrance-free soap after every use. Some toys may be boiled or placed in the dishwasher if the manufacturer’s instructions allow. Always pay special attention to any grooves or textured areas where germs may hide.

Sanitizing sex toys before and after use, and using condoms with shared toys, further reduces the risk of infection. By making toy hygiene a regular part of your routine, you help protect both your urinary and overall sexual health.

20. Ignoring Signs of UTI

Recognizing the early symptoms of a urinary tract infection is crucial for prompt treatment and preventing complications. Common signs include a burning sensation during urination, frequent urges to urinate, cloudy or foul-smelling urine, and pelvic discomfort. These symptoms can sometimes be mistaken for other conditions, such as dehydration, minor irritation, or even sexually transmitted infections. However, ignoring these early warnings allows bacteria to multiply and increases the risk of the infection spreading to the kidneys or bloodstream.

The CDC emphasizes the importance of seeking medical attention if you notice any symptoms of a UTI, especially if you develop fever, chills, or back pain—signs of a potentially serious infection. Early diagnosis allows for effective treatment, usually with antibiotics, and can help prevent long-term health issues.

If you experience any warning signs, don’t wait to reach out to a healthcare professional. Acting quickly can make all the difference in your recovery, prevent complications, and protect your urinary health in the future.

21. Not Drinking Enough Water

Hydration is one of the simplest and most effective ways to protect your urinary tract. Drinking plenty of water helps flush bacteria out of the bladder before they can multiply and cause infection. When water intake is low, urine becomes concentrated, and the urinary tract is less effective at clearing out germs. This increases the risk of UTIs, especially in people who are already prone to them.

Comparing hydration habits reveals a clear difference: those who consistently drink enough water tend to experience fewer urinary issues than those who don’t. A study published in JAMA Internal Medicine found that increasing water consumption can significantly reduce UTI recurrence in women with a history of infections.

Doctors generally recommend regular water consumption throughout the day, aiming for at least six to eight glasses unless otherwise directed by your healthcare provider. Carry a water bottle, set reminders, or infuse your water with fruit for added appeal. Staying well-hydrated keeps your urinary tract functioning optimally and is an easy, proactive step for UTI prevention.

22. Using Public Restrooms without Protection

Public restrooms are high-traffic areas where germs can easily spread via high-touch surfaces such as toilet seats, flush handles, and door latches. While the risk of catching a UTI from a toilet seat itself is low, bacteria and viruses can linger on these surfaces and transfer to your skin, especially if the area is damp or poorly cleaned. Using public restrooms without any form of protection increases your exposure to these invisible threats.

Most public facilities offer disposable toilet seat covers, which provide an effective barrier between your skin and the seat. In the absence of covers, layering several sheets of toilet paper can offer some protection, though it may not be as reliable. The CDC also recommends thorough handwashing after using public restrooms to further reduce the risk of infection.

Whenever you must use a public restroom, take simple precautions: use seat covers or tissue, avoid placing personal items on bathroom surfaces, and wash your hands thoroughly before leaving. These habits help shield you from unnecessary bacteria, supporting your urinary tract health even outside your home.

23. Wearing Tight-Fitting Pants Often

Wearing tight-fitting pants or leggings day after day may look stylish, but it could be putting your urinary tract at risk. Tight clothing, especially those made from synthetic fabrics, tends to trap heat and moisture against the genital area. This warm, damp environment is perfect for bacteria and yeast to flourish, raising the risk of irritation, yeast infections, and UTIs.

In contrast, loose-fitting pants and skirts made from breathable materials like cotton allow air to circulate and help keep the skin dry. According to the American Academy of Dermatology, switching to looser, natural-fiber clothing can make a significant difference in reducing the risk of infections for those prone to urinary or vaginal problems.

To protect your urinary health, balance fashion with function: reserve tight pants for occasional wear and opt for looser, breathable attire for everyday use. If you do wear tight clothing, change out of it as soon as possible after sweating or exercising. Making this simple wardrobe adjustment can help keep your body healthy and comfortable.

24. Failing to Dry Off Properly

After bathing or swimming, it’s easy to overlook the importance of thoroughly drying your body—especially sensitive areas. Lingering moisture on the skin fosters bacterial and fungal growth, particularly in enclosed, warm environments like the groin. When moisture is trapped against the skin by underwear or clothing, bacteria can multiply and increase your risk of urinary tract infections and skin irritation.

While air-drying may seem gentle, towel-drying is far more effective at removing excess water from the skin’s surface. The CDC recommends using clean, dry towels to pat—rather than rub—your body dry, paying special attention to skin folds and the area between your legs.

To support urinary health, always dry off completely after showering, bathing, or swimming. If you’re in a hurry, use a soft, absorbent towel and change into dry clothes as soon as possible. By making thorough drying part of your daily routine, you help minimize the risk of bacterial growth and keep your skin healthy and comfortable.

25. Using Unwashed Hands to Insert Tampons

Inserting a tampon with unwashed hands can easily transfer bacteria from your fingers to the vaginal and urinary tract. The genital area is particularly vulnerable to bacterial invasion, and even brief contact with dirty hands can introduce microbes that increase the risk of urinary tract infections, vaginal infections, or even toxic shock syndrome.

Comparing the outcomes, those who consistently wash their hands before inserting tampons have a much lower risk of developing infections than those who don’t. The CDC emphasizes hand hygiene as a key measure to prevent the spread of harmful germs—especially before handling items that come into contact with mucous membranes.

To protect your health, always wash your hands thoroughly with soap and water before inserting a tampon or menstrual cup. If soap and water are unavailable, use an alcohol-based hand sanitizer as a temporary alternative. This easy habit goes a long way in minimizing your risk of infection and supporting your overall reproductive and urinary health.

26. Overusing Panty Liners

Panty liners can be a convenient solution for managing minor discharge or spotting, but overusing them can have unintended consequences for your urinary and vaginal health. Daily use of liners—especially those made from synthetic materials—traps heat and moisture against the skin. This warm, damp environment encourages the growth of bacteria and yeast, raising the risk of irritation, infection, and even UTIs.

Occasional use, such as during the days leading up to your period or when you anticipate light discharge, is generally safe. However, wearing liners every day, particularly without changing them frequently, can disrupt the natural balance of flora and lead to discomfort. According to the American Academy of Dermatology, moderate use and opting for breathable, unscented liners are best practices.

Doctors recommend limiting panty liner use to when truly necessary and changing liners often to keep the area dry. On most days, wearing cotton underwear without liners allows your skin to breathe and helps maintain a healthier environment for your urinary and reproductive systems.

27. Letting Toilet Paper Touch Surfaces

Toilet paper may look clean, but it can quickly become contaminated if it touches bathroom surfaces such as countertops, floors, or even the toilet tank. High-touch areas in bathrooms often harbor bacteria, viruses, and mold—microbes that can easily transfer onto toilet paper, especially in public or shared restrooms. Once contaminated, using this toilet paper can bring bacteria into direct contact with sensitive genital or urinary areas, increasing the risk of infection.

Protected rolls—those stored in closed dispensers or cabinets—are less likely to pick up germs compared to exposed rolls left out in the open. The CDC recommends minimizing contact between hygiene products and potentially dirty surfaces to reduce your risk of exposure.

Whenever possible, avoid using toilet paper that has come into contact with bathroom surfaces. Tear off the needed amount without letting the roll touch the toilet or sink, and opt for facilities with covered dispensers. Practicing this small precaution helps keep bacteria at bay and supports your urinary health.

28. Not Disinfecting Toilet Handles

Toilet handles are among the most frequently touched surfaces in any bathroom—and they can rapidly accumulate bacteria, viruses, and other germs. Every flush transfers microbes from hands or even from toilet plume onto the handle, creating a hotspot for contamination. When cleaning is infrequent, these bacteria can persist for days, ready to be picked up and transferred to your skin or nearby surfaces.

Frequent cleaning with disinfectant wipes or sprays greatly reduces the microbial load compared to rare or superficial cleaning. According to the CDC, regular disinfection of high-touch bathroom surfaces is vital in preventing the spread of illness—including those that can affect the urinary tract.

To support your family’s health, make it a habit to disinfect toilet handles at least once a week, or more often in shared or public restrooms. Use EPA-approved disinfectant products and let them sit for the recommended time. This small step in your cleaning routine can significantly reduce the risk of transferring germs and help keep your bathroom a safer space.

29. Using Shared Soap Bars

While soap is meant to clean, shared soap bars can actually harbor and transfer germs between users. Bacteria, fungi, and even traces of skin cells can accumulate on the surface of a bar, especially when it remains damp between uses. When multiple people use the same bar, these microbes can be passed from person to person, increasing the risk of minor skin infections and potentially introducing bacteria near sensitive areas like the urinary tract.

In contrast, liquid soap dispensed from a pump is far less likely to become contaminated. According to research cited by the CDC, liquid soap containers reduce the risk of microbial growth and transfer, making them a safer choice—especially in shared bathrooms.

To minimize the risk of bacteria transfer, use a personal bar of soap or switch to liquid soap for hand and body washing. If you must use a bar, ensure it dries completely between uses and is stored in a well-ventilated holder. These small changes can contribute to better hygiene and lower your risk of infection.

30. Ignoring Leaky Faucets

A leaky faucet may seem like a minor annoyance, but it can create a moist environment that encourages the growth of bacteria, mold, and mildew in your bathroom. Constant drips keep sinks and surrounding areas damp, providing the perfect conditions for germs to multiply—not only on the faucet itself but also on nearby surfaces where water accumulates. Over time, these moist spots can harbor harmful bacteria that may be transferred to your hands or hygiene items.

Dry sinks, on the other hand, are far less likely to foster bacterial growth and are easier to keep clean. According to the CDC, eliminating sources of standing moisture in the home is an important step in maintaining a healthy environment and preventing the spread of infection.

Don’t ignore that persistent drip—repair leaky faucets as soon as possible and wipe up standing water daily. Regularly disinfect sink areas and make sure your bathroom is well-ventilated. These simple maintenance steps not only save water but also help keep your bathroom free of unnecessary germs and lower the risk of infection.

31. Using Toilet Brushes Infrequently

Toilet brushes are essential for keeping your toilet bowl clean, but they can also become germ magnets if not cared for properly. When brushes are used infrequently or not disinfected regularly, they collect bacteria, mold, and even fecal matter, which can then be spread around the toilet bowl and surrounding areas during each use. This reservoir of microbes poses a risk not just to the toilet itself, but also to anyone cleaning or using the bathroom.

Regularly cleaned and disinfected brushes are far less likely to harbor harmful bacteria compared to those cleaned sporadically. The CDC recommends frequent sanitation of bathroom cleaning tools, including toilet brushes, to minimize microbial buildup and maintain a healthier bathroom environment.

After each use, rinse the toilet brush thoroughly with hot water and disinfect it with a bleach solution or antibacterial spray. Allow it to dry completely between uses, and replace old or worn brushes periodically. These small steps help prevent the spread of bacteria and keep your bathroom—and urinary tract—safer.

32. Not Cleaning Toothbrush Holders

Toothbrush holders are often overlooked during bathroom cleaning, yet they can quickly become hotbeds for germs. Water splashes from washing hands, brushing, or even flushing with the lid up can deposit bacteria and mold onto and inside the holder. Over time, this moisture-rich environment provides the perfect conditions for microbes to thrive, potentially contaminating your toothbrush and spreading germs throughout the bathroom.

Open holders are particularly susceptible to contamination from airborne particles, while covered holders can offer some protection if kept clean and dry. According to the CDC, it’s essential to regularly clean and dry toothbrush holders to reduce the risk of germ buildup.

For optimal hygiene, clean your toothbrush holder at least once a week using hot, soapy water or a disinfectant spray. Allow it to dry completely before replacing your toothbrush. This simple habit not only prevents bacterial growth but also helps maintain a healthier bathroom environment for you and your family.

33. Letting Pets in the Bathroom

It may seem harmless—or even cute—to allow your pets into the bathroom, but this habit can introduce additional germs and pet hair to an already high-risk area. Pets, especially dogs and cats, can shed fur, track in dirt, and spread bacteria from their paws and fur onto bathroom floors, surfaces, and even toilet seats. These microbes can linger long after your pet has left, increasing the overall germ load in your bathroom.

Pet-friendly bathrooms tend to have more hair, dander, and microbial contamination compared to pet-free spaces. According to the CDC, minimizing pet access to certain areas—especially where hygiene is critical—can help reduce the risk of bacterial and parasitic infections for humans.

For optimal cleanliness, limit your pet’s access to the bathroom, particularly if someone in your household is prone to urinary tract infections or has a weakened immune system. If your pet does enter, clean surfaces frequently and keep toilet lids closed. These steps reduce unnecessary exposure to germs and help maintain a healthier bathroom environment for everyone.

34. Storing Toothbrushes Near the Toilet

Storing toothbrushes close to the toilet can expose them to the phenomenon known as toilet plume—the dispersal of microscopic droplets containing bacteria and viruses that occurs with each flush, especially if the lid is left up. These aerosolized germs can settle on nearby surfaces, including your toothbrush, making it a potential vehicle for bacteria entering your mouth and, indirectly, your digestive and urinary systems.

Research published in the Journal of Applied Microbiology shows that toothbrushes stored less than a few feet from the toilet can harbor significantly more bacteria than those kept in a closed cabinet or farther away. Covered holders provide some protection, but distance is the best defense.

To minimize germ exposure, store toothbrushes as far from the toilet as possible, ideally in a closed cabinet or behind a protective cover. Always close the toilet lid before flushing and rinse your toothbrush before each use. These simple adjustments help reduce the risk of contamination and promote a healthier, safer bathroom routine.

35. Not Changing Shower Curtains Regularly

Shower curtains, especially when left damp, are prime real estate for mold, mildew, and bacteria to flourish. Both fabric and plastic curtains can accumulate soap scum and moisture, providing an ideal environment for microbes to thrive. Over time, touching or brushing against a contaminated curtain can transfer bacteria or mold spores to your skin, increasing the risk of irritation, allergic reactions, or even infection if the germs reach sensitive areas.

Fabric curtains are generally easier to clean, as most can be tossed in the washing machine with hot water and detergent. Plastic curtains, while resistant to water, can develop stubborn biofilms that require thorough scrubbing or replacement. According to the CDC, routine cleaning and drying of bathroom surfaces—including shower curtains—helps keep mold and bacterial growth in check.

For optimal hygiene, wash or replace your shower curtain regularly, at least once a month or more often if you notice buildup or odors. Always allow the curtain to dry fully after each use by spreading it out. This simple habit helps maintain a cleaner bathroom and supports your overall health.

36. Using Expired Bathroom Products

Expired bathroom products—such as creams, ointments, lotions, and even personal cleansers—can pose a hidden risk to your health. Over time, preservatives in these products break down, leaving them vulnerable to contamination by bacteria, mold, and yeast. Using old or expired items on your skin or near sensitive areas can introduce harmful microbes, leading to irritation, allergic reactions, or infections, including UTIs.

Fresh, unopened products are less likely to harbor bacteria and are designed to deliver the advertised protective or cleansing benefits. In contrast, expired items may separate, smell off, or appear discolored—clear signs that their safety and effectiveness are compromised. The FDA advises consumers to always check expiration dates and to discard any product that looks or smells abnormal.

For safer hygiene, regularly review the expiration dates on all bathroom products, and replace items as needed. Store them in a cool, dry place and always close containers tightly after use. These simple checks can keep your bathroom safer and help protect your skin and urinary tract from unnecessary exposure to harmful microbes.

37. Neglecting to Wash Reusable Period Products

Reusable period products—such as menstrual cups, cloth pads, and period underwear—are eco-friendly and cost-effective, but they require meticulous cleaning to stay safe. If not washed thoroughly and regularly, these products can accumulate bacteria, yeast, and even traces of menstrual blood, providing a rich environment for microbes to multiply. Reusing improperly cleaned items increases the risk of vaginal and urinary tract infections, skin irritation, and odors.

The difference between proper and improper cleaning is significant. According to Planned Parenthood, menstrual cups should be washed with mild, fragrance-free soap and water after each use and sterilized by boiling between cycles. Cloth pads and period underwear require hot water washing and thorough drying before reuse.

To protect your health, follow manufacturer instructions for cleaning reusable products and never skip a wash. Store items in a dry, clean place between uses. This extra care ensures your reusable period products remain safe, comfortable, and hygienic—helping you avoid unnecessary infections and maintain healthy bathroom habits.

38. Touching Face After Bathroom Use

Touching your face after using the bathroom can inadvertently transfer bacteria and viruses from your hands to your mouth, nose, and eyes—areas where germs can easily enter the body. Even with handwashing, traces of microbes may remain under the nails or on the skin. Habitual face-touching post-bathroom increases the risk of introducing pathogens that can cause not only colds and flu but also more serious infections, including those that may affect the urinary tract indirectly through cross-contamination.

People who are mindful of their hygiene—thoroughly washing their hands and resisting the urge to touch their face—tend to experience fewer infections than those with less careful habits. The CDC highlights the importance of minimizing hand-to-face contact, especially after using the restroom or handling bathroom surfaces.

To protect yourself, avoid touching your face after bathroom use until you’ve washed your hands thoroughly with soap and water. If you must touch your face, consider using a clean tissue or the back of your hand. Developing this habit is a simple but powerful step in reducing your risk of illness.

39. Using Shared Bath Mats

Bath mats are notorious for collecting moisture, dirt, and bacteria due to their constant exposure to wet feet and humid bathroom air. When several people share the same mat, microbes, fungi, and even skin cells are easily transferred from one person to another. This can lead to the spread of athlete’s foot, yeast infections, and even bacteria that could migrate to the urinary tract, especially if the mat stays damp between uses.

Individual bath mats greatly reduce this risk, as each person is only exposed to their own germs. According to the CDC, fabrics that remain moist can harbor significant amounts of bacteria and should be washed regularly. Regular laundering with hot water and thorough drying ensures that mats remain clean and safe for use.

For optimal bathroom hygiene, assign separate mats to each household member when possible and wash all mats at least once a week. By keeping bath mats clean and dry, you protect yourself and your family from unnecessary germ exposure and support better urinary and skin health.

40. Not Replacing Toilet Brush Holders

Toilet brush holders are often overlooked when it comes to bathroom hygiene, yet they can quickly become repositories for bacteria, mold, and lingering moisture. When a wet brush is returned to its holder, drips and residual water collect at the bottom, creating a perfect environment for microbial growth. Over time, old holders can become caked with grime and invisible biofilms, further increasing the risk of contamination every time you use or handle the brush.

New holders, by contrast, are clean and free from accumulated dirt, reducing the likelihood of harboring harmful bacteria. The CDC recommends regular cleaning and replacement of bathroom accessories that are exposed to moisture and bodily waste, as these can act as reservoirs for germs that may spread to other surfaces—or even to your hands during cleaning tasks.

To maintain a healthier bathroom, replace your toilet brush holder periodically, especially if it shows signs of buildup or persistent odor. Clean it regularly, allow it to dry between uses, and choose designs that drain easily. This small upgrade can make a big difference in keeping your bathroom environment safer for everyone.

41. Using Air Dryers Instead of Paper Towels

While air dryers are promoted as eco-friendly alternatives to paper towels in public restrooms, several studies suggest these devices may actually spread bacteria and viruses rather than reduce them. High-powered air streams can blow microbes from hands and surrounding surfaces into the air, increasing the risk of contaminating yourself and others. According to research published in the Journal of Applied Microbiology, air dryers can disperse bacteria up to several feet away, landing on restroom surfaces and even on freshly washed hands.

In contrast, paper towels physically remove moisture and bacteria from the skin and can be disposed of immediately, limiting the opportunity for germs to linger or spread. The CDC notes that paper towels are the most hygienic method for drying hands, particularly in healthcare or high-risk environments.

For better personal hygiene, choose paper towels over air dryers whenever possible. If air dryers are your only option, avoid touching your face afterward and consider using hand sanitizer for an extra layer of protection. These choices help reduce your risk of germ exposure in public restrooms.

42. Not Cleaning Under Toilet Seats

It’s easy to focus cleaning efforts on the visible parts of a toilet seat, but the underside often harbors a surprising amount of bacteria, urine splashes, and even fecal matter. These hidden germs can multiply quickly in the moist, warm environment beneath the seat, making it a potential source of cross-contamination—especially when the seat is lifted or lowered during use.

Bathrooms that are meticulously cleaned—including the underside of toilet seats—have significantly lower germ counts than those where this area is neglected. According to the CDC, thorough cleaning of all toilet surfaces, including hard-to-reach spots, is essential for reducing the risk of illness and keeping bathrooms sanitary.

To safeguard your health, lift the seat and clean underneath at least once a week using a disinfectant wipe or spray. Don’t forget to target the hinges and edges, where grime often accumulates. Paying attention to this overlooked area is a simple but highly effective way to minimize bacterial buildup and promote a cleaner, safer bathroom.

43. Flushing Feminine Products

Flushing feminine hygiene products—such as pads, tampons, and wipes—down the toilet may seem convenient, but it can lead to serious plumbing issues and unsanitary conditions. Unlike toilet paper, these products do not break down easily and can quickly create blockages in pipes and sewage systems. This can result in backups and overflows, potentially exposing your bathroom to raw sewage and harmful bacteria, which significantly increases the risk of contamination and infection.

Proper disposal involves wrapping used products in toilet paper or their original packaging and placing them in a lined trash bin. Many public restrooms provide dedicated sanitary disposal bins to prevent plumbing problems and maintain hygiene. According to the U.S. Environmental Protection Agency (EPA), improper disposal of hygiene products is a leading cause of costly sewage backups and environmental pollution.

For a cleaner, safer bathroom, never flush feminine products. Always dispose of them in the trash, and educate family members about the risks of flushing. This simple change protects your plumbing and helps keep your bathroom free from unsanitary overflow and bacterial hazards.

44. Not Washing Hands After Touching Phones

Your smartphone is likely the dirtiest object you handle each day, accumulating bacteria, viruses, and other microbes from every surface it touches—including your hands, purse, counters, and even public restrooms. Studies show that phones can harbor more germs than a toilet seat, making them a significant source of contamination. When you handle your phone in the bathroom and then touch your face or other surfaces without washing your hands, you risk transferring these germs into your body or spreading them throughout your environment.

Clean surfaces, such as freshly washed hands or sanitized countertops, pose much less risk than frequently touched devices. According to the CDC, proper handwashing after handling potentially dirty items is vital for preventing the spread of illness.

To reduce your risk, make your bathroom a phone-free zone and always wash your hands after touching your phone—especially before eating, touching your face, or handling hygiene products. This small change in habit can greatly decrease your exposure to harmful microbes and keep both you and your bathroom healthier.

45. Using Communal Loofahs

Communal loofahs and bath sponges may seem like a convenient way to save space or money, but sharing them exposes everyone to bacteria, mold, and dead skin cells from each user. Loofahs are especially prone to holding moisture, creating the perfect environment for microbes to thrive between uses. When shared, these germs can be easily transferred from one person’s skin to another, raising the risk of skin infections, irritation, and even the spread of bacteria that could reach sensitive urinary or genital areas.

Personal loofahs, when cared for properly, significantly reduce this risk. According to the CDC, bath tools that remain wet and are used by multiple people are hotspots for microbial growth and should be replaced or sanitized regularly.

For better hygiene, assign a separate loofah to each family member and let it dry fully between uses. Disinfect or replace loofahs every few weeks. This individual approach not only prevents the spread of bacteria and mold but also supports healthier skin and urinary tract health.

46. Not Cleaning Around Toilet Base

The area around the base of the toilet is a frequent bacterial hotspot that’s often overlooked during routine cleaning. Splashes, drips, and accidental spills can accumulate on the floor, creating damp patches that encourage the growth of bacteria, mold, and unpleasant odors. Over time, these microbes can be tracked throughout the bathroom, contaminating other surfaces and increasing the risk of exposure, especially for young children or anyone who kneels or drops items near the toilet.

Superficial cleaning—like a quick mop around the toilet—rarely addresses the grime that builds up in corners and crevices. By contrast, thorough cleaning with a disinfectant, focusing on both the visible floor and the hard-to-reach areas behind and beside the toilet, significantly reduces bacterial load. The CDC recommends regular, detailed cleaning of bathroom floors to minimize the spread of germs.

Make it a habit to clean around the toilet base at least once a week, using a dedicated cloth or disposable wipes. Paying attention to this often-ignored area is a simple but effective step in keeping your bathroom safer and healthier for everyone.

47. Ignoring Signs of Mold

Mold thrives in moist, poorly ventilated bathrooms and is more than just an eyesore—it can contribute to respiratory issues and infections, particularly in people with weakened immune systems. Mold spores can irritate the skin, eyes, and airways, and in rare cases, may promote the growth of bacteria that could migrate to the urinary tract. Bathrooms are especially vulnerable due to frequent steam and condensation.

While visible mold (black, green, or brown patches) is an obvious red flag, hidden mold—behind tiles, under sinks, or around window frames—can also be a source of chronic irritation and infection. According to the CDC, all mold, whether seen or unseen, should be treated seriously and removed promptly.

Conduct regular inspections of your bathroom, paying attention to corners, grout, and less accessible areas. Address leaks and improve ventilation to prevent mold growth, and clean any discovered mold with an appropriate cleaner. By staying vigilant, you protect your household from unnecessary health risks associated with mold exposure.

48. Using Old Toothbrushes

Over time, toothbrushes can become breeding grounds for bacteria, mold, and yeast, especially when kept in damp bathrooms. As bristles wear down and accumulate debris, they become less effective at cleaning and more likely to harbor germs. Using an old toothbrush increases the risk of transferring these microbes to your mouth—and potentially spreading them to other body parts, including the urinary tract through indirect contact.

Regularly replacing your toothbrush is key to maintaining oral and overall health. The CDC recommends switching to a new toothbrush every 3 to 4 months, or sooner if the bristles become frayed or after illness. Fresh toothbrushes are more effective at removing plaque and less likely to transfer bacteria with each use.

Make it a habit to mark your calendar or set reminders for toothbrush changes. Store your brush upright and allow it to air dry between uses, keeping it away from toilets and sinks. These small steps can help keep germs at bay and support better hygiene throughout your daily routine.

49. Not Cleaning Faucet Handles

Faucet handles are among the most frequently touched surfaces in any bathroom, making them prime spots for germ accumulation. Every time you turn the tap on or off—especially with unwashed hands—bacteria, viruses, and other microbes are transferred onto the handles. Over time, these areas can become hotspots for the spread of illness throughout your household, especially if cleaning is inconsistent.

Regular cleaning and disinfection keep faucet handles relatively germ-free, while infrequent cleaning allows bacteria to multiply and persist for days. According to the CDC, weekly disinfection of high-touch bathroom surfaces is essential for maintaining a healthy environment and reducing your risk of infection.

To limit germ exposure, disinfect faucet handles at least once a week using EPA-approved disinfectant wipes or sprays. Don’t forget to target both the top and underside of each handle, where grime often accumulates. This simple, regular task is a powerful step toward a cleaner bathroom and better personal hygiene.

50. Letting Kids Skip Handwashing

Children are notorious for spreading germs—they touch everything, share toys, and often forget basic hygiene practices like handwashing. When kids skip washing their hands after using the bathroom, they can easily transfer bacteria and viruses to themselves, other children, and surfaces throughout the home. This puts everyone at greater risk for illnesses, including urinary tract infections and stomach bugs.

Supervised handwashing routines are far more effective than leaving children to wash up on their own. According to the CDC, teaching children to wash their hands thoroughly with soap and water for at least 20 seconds is one of the best defenses against spreading germs. Parents and caregivers play a crucial role in modeling and enforcing these habits.

Make handwashing fun and memorable by singing songs or using colorful soaps, and offer regular reminders after every bathroom visit. Consistency and supervision are key to building lifelong healthy habits. By investing time in teaching proper hand hygiene, you help protect your child’s health—and the whole household—from preventable infections.
