How to Unclog a Bathroom Sink

A clogged bathroom sink can disrupt your daily routine and create unnecessary stress. Whether it's a wall mount bathroom sink or bathroom sinks with faucets, they all face the same risk—blockages caused by a buildup of hair, soap scum, and debris. Fortunately, unclogging your bathroom sink is a straightforward process when you know the right steps and tools to use.

This comprehensive guide will walk you through how to unclog a bathroom sink, the most common causes of clogs, effective DIY solutions, and tips on preventing future blockages. If you prefer tables and systematic instructions, you'll find this guide particularly handy.

Common Causes of Bathroom Sink Clogs

Before we jump into how to fix the issue, it’s essential to understand what typically causes a bathroom sink to clog. Recognizing these culprits can help prevent future clogs.


Causes Description
Hair Hair falls into the sink during grooming and mixes with soap scum, creating clumped blockages.
Soap Scum and Dirt Residue from soaps hardens over time and narrows the drain pipe.
Toothpaste Buildup Sticky toothpaste gathers in pipes, mixing with other debris to form blockages.
Small Objects Items like jewelry, toothpaste caps, or other small things accidentally washed down the sink.
Grease and Oils While uncommon for bathroom sinks, oil-based products like lotions can solidify and cause clogging.


By identifying these common issues, you can take proactive steps to minimize the risk of clogs.

Essential Tools to Unclog a Bathroom Sink

Preparation is key when tackling a clogged sink. Below is a list of essential tools and materials you may need:


Tool/Material Purpose
Plunger Creates suction or pressure to dislodge small clogs.
Pipe Snake (or Auger) Breaks apart or removes deep, stubborn blockages.
Baking Soda and Vinegar Combines to form a natural cleaning agent that helps dissolve grease and buildup.
Boiling Water Softens grease buildups and flushes out minor clogs.
Bucket and Wrench Used to remove the P-trap for thorough cleaning.
Rubber Gloves Protects your hands and keeps the process sanitary.


Having these tools on hand will make the unclogging process much easier.

Step-by-Step Guide to Unclogging Your Bathroom Sink

Now that you have your tools ready, let's get started. Below is a step-by-step process to unclog your bathroom sink:

1. Use Boiling Water

Boil a pot of water and pour it directly into the drain. This loosens minor clogs caused by grease or soap scum. Repeat this 2-3 times if necessary, allowing the hot water to work for a minute between pours.

Tip: Avoid boiling water if you have PVC pipes, as extreme heat can damage them.

2. Try Baking Soda and Vinegar

Pour 1/2 cup of baking soda into the drain. Follow up with 1/2 cup of white vinegar. Cover the drain with a rag or stopper to contain the fizzing reaction. Wait for 15-20 minutes, then flush the drain with hot water.

This method is eco-friendly and works best for minor clogs.

3. Use a Plunger

Place the plunger over the drain, ensuring a tight seal. Fill the sink with enough water to cover the rubber part of the plunger. Push and pull forcefully for about 30 seconds to create suction. Remove the plunger and check if water drains. Repeat if necessary.

4. Clean the P-Trap

Place a bucket under the sink to catch any water. Use a wrench to loosen the slip nuts and remove the P-trap. Scrub away any debris or buildup using a brush or sponge. Reattach the P-trap and check for leaks before testing the drain.

5. Use a Pipe Snake (Drain Auger)

Insert the snake into the drain and push it as far as it will go. Rotate the handle to latch onto the clog and pull it out. Repeat until no blockage remains.

Tip: This method works well for wall mount bathroom sinks, as the snake can reach deep into the attached pipe system.

6. Chemical Drain Cleaner (Last Resort)

Use a commercial drain cleaner as a last option for stubborn clogs. Follow the instructions on the product and ensure proper ventilation. Note that frequent use of chemical cleaners can damage pipes over time.

If these methods do not resolve the issue, you might need to call a professional plumber to investigate the problem further.

Preventing Bathroom Sink Clogs

Preventing clogs is often simpler than dealing with them once they’ve formed. Consider the following tips to keep your bathroom sink flowing freely:


Preventive Measure Description
Use a Drain Strainer Catch hair and debris before they enter the drain.
Clean Drains Weekly Rinse with hot water or a vinegar solution to prevent buildup.
Avoid Pouring Grease or Oils Dispose of these in the trash instead of the drain.
Limit Flushing Certain Substances Only flush water, soap, and other dissolvable products down your bathroom sink.
Inspect Pipes Periodically Check and clean the P-trap every few months to remove potential blockages.


Consistency in maintenance will drastically reduce your chances of experiencing a clogged bathroom sink.
