Have you ever been caught off guard by a smell that reminds you of rotten eggs permeating your bathroom? Does that smell not seem to be going away on its own? If this scenario sounds familiar, you’re probably dealing with a sewer gas problem in your bathroom. Understandably, you want to get to the bottom of what causes sewer gas smell in bathroom. Luckily, you can find out the answer to that question by reading this blog. 

What Causes Sewer Gas Smell In Bathroom?

There are many different answers to what causes sewer gas smell in bathroom. In this blog, you’ll explore the four most common causes of this odor and how to get rid of them. 

Damaged Sewer Or Main Drain 

The most severe possible cause behind the smell of sewer gas invading your bathroom is severe damage to the connecting sewer or main drain. You’ll most likely know if this cause is the culprit if you’ve eliminated any other possible sources behind the smell. If this is the reason behind the persistent stink in your bathroom, call a plumber right away. 

Plumbing Leak 

Were you present when your home’s plumbing system was installed, or was it set up long before you moved into your current home? If your home’s plumbing was poorly installed, that could easily be the answer to what causes sewer gas smell in bathroom in your home. Have a professional check out the state of your indoor plumbing. There could be a leak or something amiss that’s causing that smell to take over your bathroom. 

Clogged Sink 

An easy way for you to find the answer to what causes sewer gas smell in bathroom is to find out if your sink is clogged. You only need to pour drain cleaner down your sink and see if the smell disappears within one or two days. If the smell fades and then disappears, that’s the smell’s source. If the sewer gas smell persists, you’ll need to consider other possible causes behind it.

P-Trap Problems 

If the smell isn’t coming from your bathroom sink, consider the possibility of the cause being related to your toilet’s P-trap. The smell could be the result of water sitting and building up in the P-trap instead of draining as it should. Find the U-shaped pipe behind the toilet and run your hand along it to see if it’s moist or damp. If so, then you’ll need to call a plumber to fix your toilet’s plumbing and P-Trap. 

Broken Seal Around The Toilet 

Another part of your toilet that could be causing the sewer gas smell is the seal that surrounds it. Specifically, a broken toilet seal. If your toilet seal is broken, you’ll just need a plumber to replace it with a new one. Hopefully, the smell of sewer gas will finally disappear from your bathroom. 

What Can Sewer Gas Smell Lead To?

The smell of sewer gas in your bathroom shouldn’t be ignored. Assuming that the smell will go away on its own can actually lead to more severe problems in the future. These problems can range from severe damage to your plumbing and HVAC systems to serious illness or other health problems.
