Why Does My Bathroom Sink Smell Like Rotten Eggs

Why Does My Bathroom Sink Smell Like Rotten Eggs?

If you've ever noticed a foul odor coming from your bathroom sink, you may have wondered what's causing it. The most common culprit is bacteria that build up in the drainpipe. These bacteria feed on organic matter, such as hair, soap scum, and toothpaste, and produce hydrogen sulfide gas as a byproduct. Hydrogen sulfide gas has a distinctive rotten egg smell.

There are a few other things that can cause your bathroom sink to smell like rotten eggs, including:

A clogged drain. If the drain is clogged, water can't flow properly and bacteria will start to grow.
A faulty garbage disposal. If the garbage disposal is not working properly, food particles can get stuck in the drain and start to rot.
A leaking sewer line. If the sewer line is leaking, hydrogen sulfide gas can escape into your home through the bathroom sink.

If you're not sure what's causing the smell, it's best to call a plumber. They can inspect your plumbing and determine the source of the problem.
