If you’ve ever had the unfortunate experience of being in a bathroom and catching a waft of rotten eggs or some other unpleasant smell then you’re not alone.

Chances are, it’s coming from your toilet and no matter how hard you try to ignore it or cover it up with air freshener and various scents, the issue still persists.

In this article, we will explore what could be causing these foul smells and provide helpful tips to help diagnose, identify and remediate any underlying problems related to why your toilet smells like rotten eggs.

What you are smelling is a gas called hydrogen sulfide (H2S) which originates directly from raw sewage flowing through pipes. If it’s coming from the septic system, bacteria may be to blame. On the other hand, if your water supply is causing a stink then only one pipeline could be at fault.

What causes a toilet to smell like rotten eggs?

There are several causes of a toilet smelling like rotten eggs, including:

Bacteria

Certain bacteria in your toilet, such as sulfate-reducing bacteria, multiply and produce hydrogen sulfide gas, which has a distinct smell of rotten eggs.

Sewer Gas

Sewer gas from bad seals around the toilet drain opening or from a dry P-trap.

Water Supply Issues

A malfunctioning water supply line can cause an unpleasant odor from the pipes running to the toilet bowl. This could be caused by corroded pipes, buildup of organic matter in the pipes, or a faulty seal.
