Smell Coming From Bathroom Sink

A foul smell coming from your bathroom sink can be an unpleasant and embarrassing problem. There are a few different reasons why this might be happening, but the most common culprits are:

Hair and soap scum: These can build up in the drain and create a breeding ground for bacteria, which can lead to a musty smell.
Food debris: If you're in the habit of rinsing food scraps down the sink, these can also get stuck in the drain and start to rot, creating a foul odor.
Clogged drain: If the drain is clogged, water can't flow through properly and this can lead to a buildup of bacteria and grime, which can cause a bad smell.
Dry P-trap: The P-trap is the curved section of pipe under the sink that prevents sewer gases from escaping into your home. If the P-trap dries out, it can no longer perform its job and sewer gases can start to seep into your bathroom.

If you're dealing with a smelly bathroom sink, there are a few things you can do to try to fix the problem yourself.

Clean the Drain

The first step is to clean the drain. 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 a few minutes, then flush it out with hot water. You can also try using a commercial drain cleaner, but be sure to follow the instructions on the label carefully.

Unclog the Drain

If the drain is clogged, you'll need to unclog it before you can clean it. There are a few different ways to do this, depending on the severity of the clog.

Use a drain snake: A drain snake is a long, flexible tool that can be inserted into the drain to break up clogs.
Use a plunger: A plunger can be used to create a vacuum that will help to dislodge the clog.
Call a plumber: If you're unable to unclog the drain yourself, you may need to call a plumber to have it professionally cleaned.

Fill the P-trap

If the P-trap is dry, you'll need to fill it up. To do this, simply pour a cup of water down the drain. The water will fill the P-trap and create a seal that will prevent sewer gases from escaping.

Prevent Future Smells

Once you've fixed the problem, there are a few things you can do to help prevent future smells from developing.

Run the water regularly: Running the water for a few seconds each day will help to keep the drain clear and prevent clogs from forming.
Avoid rinsing food scraps down the sink: Food scraps should be disposed of in the trash, not the sink.
Use a drain strainer: A drain strainer will help to catch hair and other debris before it can get into the drain and cause a clog.
Clean the sink regularly: Cleaning the sink regularly will help to remove any bacteria or grime that could cause a smell.

If you're still having problems with a smelly bathroom sink, you may need to call a plumber to have it inspected. There may be a more serious problem that needs to be addressed.
