Here’s what I’ll cover: How to remove smells from the water and why it happens (including some common causes), as well as various methods that work best when trying to eliminate those pesky odors . Let’s get started by addressing one possible cause.

Finding the Source of the Smell 

When you feel the smell of a new shower drain squeezing your nose in the bathroom, the first thing you need to do is find what kind of unpleasant odor it is, hence you can determine the possible source of the odor.

We will tell you how to deal with each of these issues therefore your bathroom will return to the refreshing, soothing environment you need without being a cave of unpleasant odors.

1. Clogged Drain 

If your bathroom shower is draining slowly, then there must be a clog in the drain. Clogs may create a bad smell as they trap grime and stop the water to drain properly. A drain clog is one of the most common issues as several elements can easily contribute to clogs, including: 

  • Hair
  • Debris
  • Small things
  • Soap 
  • Mineral deposits 
  • Sand 

2. Biofilm from a Clogged or Dirty Drain 

Biofilm is another popular reason for bad smell. The odor creates bacteria and decomposing dirt inside your drain is known as a biofilm. Those bacteria and decomposing dirt release a sticky, glue-like essence that lets them stick to your bathroom surface. 

If you want to get relief from this bad odor, you have to eliminate the blockage and debris that traps all of those bacteria.  

3. Dirty P-Trap

Dirty P-Trap is the next possible source of the smelly shower. If you notice the sewer smell in your shower drain, then this might be a Dirty P-Trap. If you check your bathroom sink, you will find a curved portion of the drain. This is called a P-trap, which attaches the sink drain with the rest of your pipes.  

This trap has a curve as it must hold a little amount of water. The sewer gas will go through your drains and bathroom if there is no water in the trap. If you feel the smell of rotten eggs in your bathroom, then the culprit will often be a dry P-trap.

4. Leaky pipes​

The above three sources of smelly showers are problems most house owners can face. But, in some cases, bathroom odors can be the cause of more serious problems that require expert help. One of these problems is pipe leakage. 

If there is any leakage in the pipes on your bathroom wall, that will let sewer gases, also called hydrogen sulphide. This may lead to drain smells like sewage or rotten eggs. 

Don’t have to worry, the little amount that you’re breathing this gas isn’t injurious to your health. However, the smell does indicate that there are issues somewhere in your drainage system. You can notice that your drain pipes are basically designed to prevent hydrogen sulphide.
