We imagine the bathroom as being a relaxing spa-like retreat. However, that's not possible in the event that a smelly odor emanates from the drain of your shower. If you're forced to keep your breath while bathing and showering, this article is suitable for you. These are the two most frequently cited causes for the smelly shower drain and the steps you can take to get rid of the problem.

Reason 1: Issue with the P-trap

If you look under the drain for your shower, you'll notice a U-shaped pipe through which water flows through. It's called P-traps, and the function is to keep the water in a tiny amount constantly to stop the sewage gasses from flowing back to the pipe and eventually into the bathroom.

If you haven't been in the shower for a while, it is possible that the water inside the P-trap has disappeared. This is a simple fix. Just run the water in your shower for a couple of minutes, and the P trap will replenish, and the smell should disappear.

If you've taken a shower in the last few days, it's a sign of an issue with the P-trap. If this is the case, the pipe must be replaced in order to eliminate the smell and avoid any further damage to your home.

Reason 2: The reason for the buildup of biofilm

Biofilm is a fine, transparent layer of bacteria that could develop from soap, water shampoo, and body oils that pass through the drain of the shower and build up in the pipes. It does not just sound disgusting, but it also can stink quite badly.

How can we get rid of biofilm? You can try to kill the bacteria using one of these solutions for your home:

Combine 1 part bleach with 1 part water. Then pour it down the drain.

Pour one teaspoon of baking soda into the drain. Add a cup of white vinegar. Then cover the drain while the mixture begins to fizzle, then flush it out with hot water.

If hair becomes stuck in drains and pipes, it may cause the biofilm problem to get more difficult (not to mention causing an obstruction). Most of the time, if you get rid of the hair, the smell will vanish.
