Why Does My Shower Drain Smell?
A shower is meant to be a space of relaxation and refreshment, so when you’re greeted by a foul smell coming from the drain, it can be hard to ignore.
We’ll dig into the most likely reasons why your shower drain smells bad, what you can do to tackle the issue, and when it’s time to call in professional help. Whether you’re dealing with a drain that smells like sewage, a musty odor, or something in between, we’ve got you covered with actionable advice to keep your bathroom smelling fresh.
Common Causes of a Smelly Shower Drain
There are several reasons why your shower drain might smell, but understanding what’s causing it can help you address the problem quickly. Below are some of the most common culprits.
Dry P-Trap
The P-trap, or U-shaped pipe under your shower drain, plays an integral role in your plumbing system. It’s designed to hold water and block sewer gases from escaping through the drain. If the P-trap dries out, typically because the shower hasn’t been used in a while, those sewer gases can travel up and fill your bathroom with unpleasant odors.
Solution: If you think a dry P-trap is the reason why your shower drain smells bad, there’s an easy fix. Simply pour water down the drain to refill the P-trap. For extra freshness, follow with a mix of baking soda and vinegar, letting it bubble before rinsing it with warm water.
Clogged Drains
Hair, soap scum, and other debris can accumulate over time, causing stubborn clogs that trap water and create an unpleasant smell. If your shower drain smells like sewage, a clog might be the issue.
Solution: You can use a drain snake to remove clogs or call a professional plumber for a thorough shower drain clean. Regular maintenance can help prevent smelly shower drains in the future.
Biofilm Buildup
Biofilm is a sticky, glue-like substance made of soap scum, dirt, and other debris that clings to the inside of your drain pipes. This buildup creates a perfect environment for odor-causing bacteria, leading to unpleasant smells.
Solution: Do you think biofilm buildup could be why your shower drain smells bad? Pour a cup of baking soda, followed by distilled white vinegar, down the drain. After letting it sit for 15 to 20 minutes, flush the drain with boiling water to break up the biofilm.
Sewer Gases
If your shower drain smells like sewage, the problem might be sewer gases leaking through cracks in your drain line or pipes. This could result from damaged plumbing or issues with your septic tank.
Solution: A professional plumber can inspect your system for leaks or damaged drainage pipes.
Why Does My Shower Drain Smell Like Rotten Eggs?
If your shower drain smells like rotten eggs, the problem is most likely caused by sewer gases or sulfur bacteria. This unmistakable odor is often a sign of something going wrong in your plumbing system. It could be due to a dry P-trap, biofilm buildup, or even a crack in the drain pipe.
Sewer gases containing hydrogen sulfide create that sulfur-like smell when they escape into your home. If left unchecked, this issue can lead to health risks and more extensive plumbing damage.
DIY Methods to Tackle a Smelly Shower Drain
If your shower drain smells bad, you can try these simple DIY solutions to tackle the issue before calling in a plumber.
Boiling Water
Pouring boiling water down the drain can loosen soap scum and debris. If you have PVC pipes, be careful not to overdo it or avoid this tip altogether, as high temperatures can cause damage.
Baking Soda and Vinegar
This classic combo is a great way to tackle biofilm buildup. Pour half a cup of baking soda down the drain, followed by a cup of vinegar. Once it stops bubbling, flush with hot water.
Clean the Drain Cover
Sometimes, the issue isn’t deep in the drain but right at the surface. Remove the drain cover and clean it thoroughly to get rid of trapped hair, soap residue, and other debris.
Remove Mold Growth
Mold can accumulate around your shower tiles, drain cover, or inside the drain itself. Scrub visible mold with a mixture of chlorine bleach and warm water, taking care to wear gloves and eye protection.
