Why Does Bathroom Sink Drain Smell and How to Fix It?

A smelly bathroom sink drain can be a nuisance. It can make your whole bathroom smell bad, and it can be embarrassing if you have guests over. But what causes bathroom sink drains to smell? And more importantly, how can you fix it?

There are a few different things that can cause bathroom sink drains to smell.

Hair and soap scum buildup. Hair and soap scum can build up in the drainpipe over time, creating a clog. This can trap water and debris, which can start to smell.
Food debris. If you rinse food scraps down the sink, they can get stuck in the drainpipe and start to decompose. This can also create a bad smell.
Bacteria. Bacteria can also grow in the drainpipe, especially if it is not cleaned regularly. This can lead to a buildup of slime and other organic matter, which can smell bad.

If you notice that your bathroom sink drain is starting to smell, there are a few things you can do to fix it.

Clean the drainpipe. The first step is to clean the drainpipe. You can do this by pouring a cup of baking soda down the drain, followed by a cup of vinegar. Let the mixture sit for 15 minutes, then flush the drain with hot water.
Use a drain cleaner. If the baking soda and vinegar solution doesn't work, you can try using a commercial drain cleaner. Follow the instructions on the bottle carefully.
Call a plumber. If you've tried the above methods and the smell still hasn't gone away, you may need to call a plumber. The plumber will be able to inspect the drainpipe and identify the source of the smell.

By following these tips, you can keep your bathroom sink drain smelling fresh and clean.
