How To Clean Shower Drain Smells? 4 Basic Steps!

If your shower drain smells but is not clogged, it is still important to check and clean the drain to see if there is any buildup or mold. Below are a few steps you can take to solve the problem; check them out.

1. Clean The Drain

Even if the drain is not clogged, a buildup of soap scum, hair, and other debris can cause bad smells. Use a drain cleaner or a mixture of baking soda and vinegar to break down the buildup. Pour baking soda into the drain, followed by vinegar, and let it sit for 10-15 minutes before flushing it with hot water. 

This natural cleaning method can help eliminate any organic material causing the odor. If you prefer a commercial solution, there are many effective drain-cleaning products available.

2. Flush The P-Trap With Water

The P-trap, a curved pipe beneath your drain, is designed to hold water and create a seal that prevents sewer gases from escaping into your home. If the problem is a dry P-trap, simply running water down the drain should resolve the issue. 

You can flush the P-trap by running the shower for a few minutes to allow the trap to fill with water and form the necessary seal to block sewer gases.

3. Check For Mold Or Mildew

Inspect the shower area for any signs of mold or mildew growth. Mold thrives in moist, warm environments, and if your shower is not properly ventilated, this could be the source of the smell. 

Clean any visible mold with a mixture of bleach and water, or use a store-bought mold cleaner. Be sure to improve ventilation in the bathroom by using an exhaust fan or leaving a window open.

4. Inspect The Vent Pipe

The vent pipe in your plumbing system allows air to flow in and out, which helps water drain efficiently. If the smell persists, the issue might be a clogged vent pipe. Cleaning the plumbing vent can be the solution for those pesky smells.
