Why Does My Bathroom Smell Like Poop

Have you ever entered your bathroom and smelled something like poop? It’s unpleasant and embarrassing, especially with guests. However, it’s essential to understand that a foul odor in your bathroom is not only unpleasant, but it can also be a health hazard.

In this article, we’ll look at the reasons why your bathroom smell like poop and how to fix it. There are four main causes of the sewer or poop smell in your bathroom, and we’ll discuss each one and provide solutions to help you avoid them.

Unused Toilet

If you have a toilet that’s only used by guests, the water in the bowl can dry out and let out gases, creating a poop-like smell. This can be unpleasant for your guests, so it’s important to run water in the bowl occasionally to prevent it from drying out.

Solution: To avoid a bad smell in your guest toilet, make sure to run water in the bowl from time to time. This will prevent the water from drying out and releasing gases that create a poop-like smell.

Clogged Toilet

If your toilet is clogged, it can cause a poop-like smell in your bathroom. Harmful bacteria in the sewage can make you sick with illnesses like gastroenteritis, hepatitis A, or cholera. It’s important to fix a clogged toilet right away to prevent the smell and health risks.

Solution: If you have a clogged toilet, you can use a plunger to remove the blockage. But if the clog is severe, call a plumber to use specialized equipment to remove it. It’s crucial to act fast to prevent the problem from getting worse.

Dry P-trap

A dry P-trap is another cause of a poop-like smell in your bathroom. The P-trap is a U-shaped pipe under the sink or shower that holds water to stop sewer gases from entering your bathroom. If the P-trap dries out, it can’t block the sewer gases, which causes a bad smell.

Solution: To fix a dry P-trap and eliminate the poop-like smell, pour a bucket of water down the drain to refill the P-trap. You can also use a non-toxic drain cleaner to clean the pipe and remove any blockages.

Faulty Wax Ring

A faulty wax ring can also cause your bathroom to smell like poop. The wax ring is a seal that connects the toilet to the sewer line. If you have a damaged or improperly sealed wax ring, sewage gases can leak into your bathroom, creating an unpleasant poop-like smell.

Solution: To fix a faulty wax ring, you will need to replace the wax ring. This is a job best left to a plumber as it requires removing the toilet to replace the wax ring.

Full Septic Tank

Bathroom waste usually settles at the bottom of your septic tank where it breaks down. However, if it rises higher than normal, it can clog the pipes in your home.

When your septic tank is full, you might notice a sewer smell in your bathroom, slow drainage, gurgling water, and waste backing up into your tub drains and toilets.

Solution: If you have a full septic tank, you should call a plumber to drain it. They will use a long hose to pump out the tank.

Lack of Air Ventilation

Lack of ventilation in your bathroom can also cause it to smell like poop. When there’s no proper airflow, moisture and bacteria build-up in the bathroom, leading to an unpleasant odor.

Solution: To get rid of the poop-like smell in your bathroom, you need fresh air to dilute it. You can do this by turning on the fan or opening a window to increase airflow.

Sewer Line Issues

A damaged or broken sewer line can also cause a foul smell in your bathroom. This happens when sewage gases leak into your home due to a damaged sewer line, resulting in an unpleasant odor.

Solution: To fix a broken or damaged sewer line causing the poop-like smell in your bathroom, it’s important to call a plumber. The plumber will diagnose and fix the sewer line issue. Depending on the severity of the problem, the plumber may need to replace the damaged section of the sewer line.

Mold Growth

If you have mold in your bathroom, it can create a smell like poop. Bathrooms are often warm, damp, and poorly ventilated, which are perfect conditions for mold growth. When mold builds up, it emits a musty smell that can resemble a poop-like odor.

Solution: For best results, use a brush to clean the parts under the rim of your toilet. You can use bleach or vinegar to achieve optimal cleanliness.

Is it Harmful for Your Health?

A bathroom that smells like poop isn’t just unpleasant, it can also harm your health. Breathing in these gases for a long time can lead to respiratory issues, headaches, and nausea. The smell can have harmful bacteria and viruses that cause illnesses. For instance, poop smell has hydrogen sulfide, which can hurt your breathing, and ammonia, which can irritate your eyes and throat.

It’s easier to prevent a foul odor in your bathroom than to try and eliminate it. Here are some steps you can take to prevent a foul smell from developing in your bathroom:

Regular Cleaning

Cleaning your bathroom regularly is crucial to prevent a foul smell. Make sure to clean your toilet, sink, and shower often to prevent bacteria and germs from building up. Use a disinfectant cleaner to wipe down surfaces, remove stains, and get rid of dirt. It’s essential to clean the areas around the toilet bowl and the base of the toilet too. If you have a shower or bathtub, use a shower cleaner to get rid of any soap scum or mildew.

Proper Ventilation

Good ventilation is also critical to prevent a foul smell in your bathroom. If your bathroom has a window, make sure to open it and allow fresh air to circulate. If your bathroom lacks a window, it’s a good idea to install a ventilation fan. This fan can remove moisture and prevent the buildup of odors, which will help keep your bathroom smelling fresh.

Regular Maintenance

To prevent a foul smell in your bathroom, regular maintenance of your plumbing system is crucial. Schedule regular maintenance checks with a plumber to inspect for any leaks, blockages, or other plumbing issues that could cause a foul odor. This will help ensure that your plumbing system is in good condition and functioning properly, which can prevent unpleasant smells from developing in your bathroom.

Proper Disposal of Waste

To prevent a foul smell in your bathroom, it’s crucial to dispose of waste properly. Only flush toilet paper and human waste down the toilet, as other items like wipes, tampons, or paper towels can cause a clog. Dispose of waste correctly in a trash can or compost bin to keep your bathroom smelling fresh.


In conclusion, a foul odor in your bathroom can be both unpleasant and a health hazard. The most common causes of a bad smell in your bathroom include a clogged toilet, a dry P-trap, a faulty wax ring, or sewer line issues. To prevent a foul odor in your bathroom, make sure to clean regularly, ensure proper ventilation, schedule regular plumbing maintenance, and dispose of waste correctly. If you can’t eliminate the smell on your own, it’s crucial to contact a professional plumber to diagnose and fix the issue. Remember, taking preventive measures is crucial to maintaining a fresh and clean-smelling bathroom.
