How to Unclog a Bathroom Sink

To unclog a bathroom sink, you need to know the basics of how the sink works and what type of clog you are dealing with.

How to Unclog a Bathroom Sink

What do you do when your bathroom sink becomes clogged? Well, before you start calling a plumber, there are a few things you can try yourself. In this article, we will walk you through the steps of how to unclog a bathroom sink. However, if your bathroom sink is completely clogged, you need to call a professional like Titan Plumbing And Electric.

What Causes Clogs in Your Bathroom Sink?

There are a few different reasons why your bathroom sink might become clogged.


One common cause is hair. When hair accumulates in the drain, it can create a blockage. Grease and other oils can also accumulate and cause a clog. Toilet paper or other feminine hygiene products can also get caught in the drain and cause a blockage. You can use long tweezers to remove the item causing the clog, but be careful not to push it further down the drain.

Broken Pipes

Another common cause of a clogged bathroom sink is a broken pipe. If the water can't flow freely through the pipes, it will back up and cause a clog. A plunger or drain snake can be used to clear the blockage, but you will need to call a plumber to fix the broken pipe.

Objects in the Drain

Sometimes small objects like toothpicks or Q-tips can accidentally fall down the drain and get stuck. This can also cause a clog. Try removing them with a plunger or drain snake.

Something Stuck in P-Trap

If the clog is not in the drain but further down the pipe, it might be something that is stuck in the p-trap. The p-trap is a U-shaped section of pipe located below the sink. This is where most of the clogs occur. You have to disconnect and clean out your bathroom sink P-Trap to get rid of the clog.

Soap Scum

If the water in your area is hard, it can cause soap scum to build up on the sides of the drain. This will also cause a clog. You can use baking soda and vinegar or a pot of hot water to help clear the scum.
