Before jumping into solutions, it’s important to identify the common culprits behind bathroom sink clogs. Here’s a breakdown:
Hair
One of the primary causes of blockages, hair can easily slip down the drain and get tangled, forming a clog over time.
Soap Scum
Soap residue often mixes with water minerals or other debris, creating a stubborn buildup that narrows the pipes.
Toothpaste and Personal Care Products

Foreign Objects

The Best Ways to Unblock a Bathroom Sink
Now that we know why blockages occur, let's focus on actionable steps. Depending on the severity of the clog, there are several methods you can try before calling a plumber.

3. Homemade Baking Soda and Vinegar Mixture
This natural, chemical-free method is great for breaking down organic buildup.
Step 1: Pour one cup of baking soda down the drain.
Step 2: Follow up with one cup of white vinegar.
Step 3: Cover the drain with a plug to trap the reaction.
Step 4: After 10-15 minutes, flush the drain with hot water. The combination of baking soda and vinegar interacts to create a bubbling effect that loosens clogs. Plus, it’s an eco-friendly option!
4. Drain Snake or Wire Hanger
A drain snake is a handy tool designed to remove blockages deeper within the pipes. If you don’t have one, you can make a DIY version using a wire hanger.
Step 1: Straighten the hanger and bend one end into a small hook.
Step 2: Insert the hook end into the drain and carefully fish undermount sink out debris.
Step 3: Repeat until the blockage is cleared, and flush the drain with water. This method is particularly effective for removing hair clogs.
5. Use a Chemical Drain Cleaner
Chemical solutions are best reserved for stubborn clogs, especially when all other options have failed. Follow these steps:
Step 1: Choose a high-quality drain cleaner designed for bathroom sinks.
Step 2: Read the instructions carefully and pour the recommended amount into the drain.
Step 3: Allow it to sit for the recommended time, then flush with water. Keep in mind that chemical cleaners can be harsh on plumbing systems, especially older pipes, so use sparingly.
6. Remove the Sink Trap
If none of the above methods work, you may need to access the sink trap (the U-shaped pipe under the sink). Here’s how to do it:
Step 1: Place a bucket under the sink trap to catch water or debris.
Step 2: Use a wrench to loosen the slip nuts on both ends of the trap.
Step 3: Clean out the trap and reattach it.
This method can undermount sink be messy but is often the most effective solution for deep clogs.

Flush Drains Regularly
Pour boiling water or a baking soda/vinegar mix down your drain monthly to keep it clear.
Be Mindful of Products
Use moderate amounts of toothpaste and soap, and avoid letting foreign objects go down the drain.
Check for Leaks or Build-Up
If you notice slow drainage, act early before it escalates into a full blockage.
