There’s nothing as frustrating as a clogged bathroom sink. As a result, water backs up and soap scum accumulates, resulting in a filthy, unusable sink. Fortunately, unclogging a bathroom sink is not a difficult task. Even with only a basic understanding of plumbing, you can solve the issue. How to do that? In this guide, you’ll learn the step-by-step process to help you fix your sink and get your water draining properly again.
Why Do Bathroom Sinks Clog?
Before you begin unclogging, it can be helpful to know why clogs develop. Bathroom drains are often clogged with a combination of:
Hair: Shaving and washing hair sends the strands down the drain. Hair can clump and build up over time.
Soap and scum: Soap can also make a sticky layer in pipes.
Toiletries: Things like dental floss, cotton swabs, and wipes can easily drop in and clog the drain.
Grease and oil: Facial creams, lotions, and even toothpaste coat and cling to pipes, causing gunky buildup that makes water go slow.
Deeper problems: Occasionally, the clog occurs further down the pipe or sewer line. Here, a little DIY action might not be able to fix the problem.

How to Unclog a Bathroom Sink Fast: 8 Foolproof Fixes That Work
Method 1: Hand Removal of Visually Obvious Blockage
Begin by checking if you can spot any obstructions in the drain. Hair or gunk closer to the surface can sometimes be extracted by hand. Wear gloves and use a flashlight to do it more perfectly.. If it’s not within your reach, don’t worry — there are other steps ahead.
Method 2: You Can Try a Plastic Drain Tool
A plastic drain tool has tiny hooks along its sides. You can buy it from a hardware store. How to use it? It has to be inserted into the drain bit by bit.
Insert it and wiggle it to pick up hair and debris. Then, pull it out. Repeat this several times. Wipe your tool off after every pull and keep pulling until it comes out clear.
Method 3: Hot Water Down the Drain
If it’s a small clog, hot water may cut through and melt it. I’m a how to cook scrambled egg in rice cooker lazy girl, so you know I don’t like waiting for water to boil! Gently pour it down the sink drain. Just take it slow so it doesn’t splash. Let it stand for a few minutes, then test the drain. This works best for blockages that are the result of soap or grease.
Method 4: Remove and Clean the P-Trap Under The Sink
The curved pipe under the sink is known as a P-trap. In addition to trapping water, it can also accumulate hair and debris. To collect water, place a bucket underneath the P-trap. You can loosen the connectors manually or using a wrench. Take the pipe out and check it for obstructions.
Use warm water and a brush to clean it out. Clean any parts before replacing them. Tighten the connections and turn on the water to see if the clog is gone.
Method 5: Give Baking Soda and Vinegar a Shot
If hot water doesn’t work, try a homemade cleaning mixture.
- Start by pouring one cup of baking soda down the drain.
- Add a cup of vinegar next. You will hear fizzing and see bubbles.
- This stinging reaction releases dirt and accumulation.
- Cover the drain for 30 minutes.
It would be better if you waited an hour or overnight. Pour hot water down the drain. Repeat if needed.
Method 6: Use a Plunger
You can use plungers for more than just toilets. Start by removing the drain stopper, if possible. Fill the sink with water such that the water covers the rubber head of the plunger. Place the plunger over the drain and press down slightly. And now push it up and down a few times.
Strip and test the water. If it flows slowly, do it again. Plunging generates pressure that shakes out clogs or even brings them up.
Method 7: Use a Drain Snake for Deep Clogs
If you’ve still got the stubborn clog, it may be further down the pipe. A drain snake, or auger, could be the solution. Gently insert the metal cable into the drain. As it goes in, screw the handle. It can be a pain to take out the clog later, too. To break it up, keep turning.
Pull the snake back up when it moves easily. Pass water to see if it runs clear. And, you know, clean the snake after.

Method 8: Hire a Plumber if Nothing Else Works
If you’ve tried everything and the sink is still blocked, a call to the plumber for backup is in order. There are some stubborn, complicated, or deep blockages that DIY tools just can’t break free. Your sewer line could have tree roots or broken pieces of pipe in it. A plumber can address the situation safely and effectively.
