What To Do If Your Bathroom Sink Smells

A smelly bathroom sink is a common problem that can be caused by a variety of factors. The most common cause of a smelly bathroom sink is a build-up of soap scum, hair, and other debris in the drain. This build-up can create a breeding ground for bacteria, which can produce unpleasant odours.

Other causes of a smelly bathroom sink can include:

A clogged drain
A faulty P-trap
A leaking faucet
A build-up of mould and mildew

If you have a smelly bathroom sink, there are a few things you can do to try to fix the problem.

1. Clean the Drain

The first thing you should do is 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 15 minutes, then flush the drain with hot water.

If the baking soda and vinegar solution doesn't work, you can try using a commercial drain cleaner. However, it is important to follow the directions on the package carefully, as drain cleaners can be harmful if they are used incorrectly.

2. Check the P-Trap

The P-trap is a U-shaped pipe that is located under the sink. The P-trap helps to prevent sewer gases from escaping into the bathroom. If the P-trap is clogged, it can cause a smelly bathroom sink.

To check the P-trap, remove the cleanout plug at the bottom of the trap. If the trap is clogged, you will see a build-up of hair, soap scum, and other debris. You can clean the trap by removing the debris and flushing the trap with hot water.

3. Check the Faucet

A leaking faucet can also cause a smelly bathroom sink. If the faucet is leaking, water can drip into the sink and create a breeding ground for bacteria. To check the faucet for leaks, turn on the water and look for any drips. If you see any drips, you will need to replace the faucet.

4. Clean the Sink

If the drain, P-trap, and faucet are all clean, the next step is to clean the sink. You can clean the sink by using a mild detergent and a sponge. Be sure to rinse the sink thoroughly after cleaning it.
