A smelly toilet is a common problem that can be both annoying and embarrassing. There are a number of possible causes of toilet smell, including:

  • Dirty toilet bowl: The most common cause of toilet smell is a dirty toilet bowl. When urine and feces sit in the bowl for too long, they can start to decompose and produce a foul odor.
  • Clogged toilet: Another common cause of toilet smell is a clogged toilet. When the toilet is clogged, waste can build up in the bowl and start to decompose, creating a bad smell.
  • Old wax ring: The wax ring that seals the toilet to the floor can also become a source of odor if it starts to deteriorate. As the wax ring breaks down, it can allow sewer gas to escape into the bathroom, creating a foul smell.
  • Leaking toilet: A leaking toilet can also cause a bad smell. When water leaks from the toilet, it can pool under the toilet and create a breeding ground for bacteria. This bacteria can produce a strong, unpleasant odor.
  • Plumbing problems: Other plumbing problems, such as a broken sewer line or a backed-up drain, can also cause toilet smell. These problems can allow sewer gas to escape into the bathroom, creating a foul odor.
