What Causes a Sewer Smell in the Shower Drain?

There are a few things that could be causing your shower drain to smell like a sewer. The first is that something might block the drain, preventing the water from flowing freely. This could be hair, dirt, or even soap scum.

The second possibility is that there’s something wrong with your sewer line. If the smell is really strong, it might be a sign that there’s a blockage or a leak somewhere in the line.

If you’re not sure what’s causing the smell, it’s best to call a professional to take a look and help you find a solution.

How to Identify the Source of the Smell

If your shower drain smells like sewer gas, there’s likely a clog in the drainpipe causing the smell. This problem can be caused by several things, such as soap scum, hair, dirt, debris, or even a build-up of bacteria.

The first step in identifying and fixing the smell’s source is understanding its origin. The smell will be strongest near the drain but may also be detectable in other shower parts. Once you know where the odor is coming from, you can start troubleshooting to find and fix the problem.

How to Prevent Future Smells

If you’re wondering how to prevent future sewage smells from entering your shower drain, you can do a few things. First, avoid pouring grease down the drain and use a drain strainer in the shower to catch any hair or debris that might be washed down.

Secondly, pour some hot water and an ½ cup of baking soda down the drain every few weeks to help keep it fresh and clear of blockages. Finally, add some drops of essential oils, such as lavender or tea tree oil, that naturally help reduce any nasty smells.
