  • Mildew and mold. Mildew and mold can grow in the toilet bowl or on the tank, especially if there is moisture present. This can cause a musty or moldy smell.
  • Toilet paper residue. If you do not flush the toilet paper completely, it can build up in the bowl and cause a smell.
  • Other causes. Other possible causes of a smelly toilet include:
  • A broken toilet seal

Why Does My Toilet Smell?

There are a few different reasons why your toilet might smell. The most common cause is a build-up of bacteria in the toilet bowl. This can happen if you don’t flush the toilet often enough, or if you don’t clean the toilet bowl regularly. Other possible causes of a smelly toilet include:

  • A sewage backup
  • A leak in the toilet

Fix a Sewage Backup

If you’re experiencing a sewage backup, it’s important to take action immediately. A sewage backup can be a health hazard, as it can contaminate your drinking water and spread bacteria.

To fix a sewage backup, you’ll need to find the source of the problem. This may be a clogged drain, a broken pipe, or a faulty sewer line. Once you’ve found the source of the problem, you can start to fix it.

If the problem is a clogged drain, you can try to clear it with a plunger or a drain snake. If the problem is a broken pipe, you’ll need to call a plumber to fix it. If the problem is a faulty sewer line, you’ll need to call your local sewer company to fix it.

Clean the Toilet Bowl

One of the most common causes of a smelly toilet is a build-up of bacteria in the toilet bowl. This can happen if you don’t flush the toilet often enough, or if you don’t clean the toilet bowl regularly.

To clean the toilet bowl, you’ll need a toilet brush, some toilet bowl cleaner, and a pair of gloves.

First, put on the gloves. Then, pour some toilet bowl cleaner into the toilet bowl. Use the toilet brush to scrub the inside of the toilet bowl, paying special attention to the rim and the bottom of the bowl.

After you’ve scrubbed the toilet bowl, flush it to rinse away the cleaner. Then, use a dry cloth to wipe down the outside of the toilet bowl.

Get Rid of Bacteria Growth

Bacteria can also cause a smelly toilet. This is especially true if you don’t flush the toilet often enough. To get rid of bacteria growth in your toilet, you can use a bleach solution.

To make a bleach solution, mix one part bleach with three parts water. Then, pour the bleach solution into the toilet bowl. Let the bleach solution sit for at least 15 minutes. Then, flush the toilet to rinse away the bleach solution.

Remove Mildew and Mold

Mildew and mold can also cause a smelly toilet. This is especially true if your bathroom is humid. To remove mildew and mold from your toilet, you can use a vinegar solution.

To make a vinegar solution, mix one part vinegar with two parts water. Then, pour the vinegar solution into the toilet bowl. Let the vinegar solution sit for at least 15 minutes. Then, flush the toilet to rinse away the vinegar solution.

Dispose of Toilet Paper Residue

Toilet paper residue can also cause a smelly toilet. This is especially true if you don’t flush the toilet paper completely. To avoid this problem, make sure to flush the toilet paper completely after each use.

If you’re still having trouble getting rid of the smell, you can try using a commercial toilet deodorizer. Toilet deodorizers are available at most grocery stores and home improvement stores.
