5 Reasons Your Toilet Still Smells Foul, Even After Cleaning

You’ve scrubbed all day, using every cleaner in the house, and you can’t seem to get rid of that bad toilet smell.

Foul odors from the toilet can cause major health problems if left untreated, not to mention that you don’t want to host guests when your bathroom smells like sewage.

We’ve listed some reasons why your toilet may still smell bad after cleaning and what you can do to remedy it.

1.  Clogged Pipe

A major reason your toilet may emit a foul smell is a clog in its drain pipe. Clogs like these occur when items are flushed down the toilet that shouldn’t be, such as wipes, tissues, or condoms.

You’ll want to use a plunger first to try and clear the clog. If that doesn’t work, check that your toilet uses enough water to flush, as too little water during the flushing phase can also cause these clogs.

2. Dry P-Trap

The P-Trap is the pipe beneath the toilet that makes a P shape. The main function of the p-trap is to prevent toxic gases such as methane from making their way into a home. Usually, these pipes are filled with water. However, the p-trap can get dry when a toilet is not used frequently.  If the water in the trap evaporates, it can’t capture expanding gases resulting in a foul smell inside the home.

The easiest way to solve this problem is to start flushing the unused toilet more frequently, such as a couple of times a week.

3. Bacteria

Another cause of bad smells from the toilet is bacteria growing in the toilet bowl or tank. People who live in humid climates have to be especially vigilant, as bacteria tend to grow at a faster rate in toilets where the humidity is high.

If you think bacteria may be to blame for your sewage smell issues, dilute some bleach and clean your toilet with it. You can do this by adding the bleach to the toilet tank and waiting 30 minutes before you flush.

4. Sealing Ring Issues

Around the base of your toilet is a ring that seals the toilet to the floor and keeps sewage from entering your bathroom. However, if the ring is loose or damaged, sewage may be entering your bathroom through it.

Look around the base of your toilet for cracks. You can use some caulk to patch them if you can see them. If there are no visible cracks but the toilet wobbles, you will need to call a professional plumber to come and replace it.

5. Vent Pipe Clog

For a toilet to work properly, a vent pipe must allow airflow into the system. However, as with other pipes, this vent pipe can sometimes get clogged. Since the vent's opening is typically on the roof, you will need to contact a professional plumber to inspect the pipe and replace it if necessary.
