my toilet smells bad

Plumbing

The answer to 'my toilet smells bad' is that a smelly toilet is usually caused by a buildup of bacteria, mold, or debris in the toilet bowl or tank. Common symptoms include a persistent foul odor coming from the toilet, even after flushing.

Some common causes include infrequent cleaning, a cracked or damaged toilet seal, a faulty flushing mechanism, or a problem with the plumbing vent. In many cases, the issue can be resolved with a thorough cleaning and maintenance, but more serious problems may require the help of a professional plumber.
