How to Unclog a Bathtub Drain

Why Bathtub Drains Clog

Bathtub drains clog from the same culprits as shower drains: hair, soap scum, and body product buildup. Bathtub clogs can be slightly more stubborn because bathtubs are used for longer soaks, allowing more soap and product residue to accumulate in the drain and pipes.

Step 1: Remove the Drain Cover and Stopper

Start by removing the drain cover and stopper. Many bathtub clogs are right at the stopper — pull out any visible hair and soap buildup by hand (wear gloves). This alone often restores drainage.

Step 2: Use a Drain Snake

For clogs deeper in the pipe, use a FlexiSnake Drain Weasel. Insert the flexible wand into the drain, rotate the handle to drive the micro-hook tip into the clog, and pull out the hair mass. The 5 disposable wands let you use a fresh one for each attempt. This is the most effective method for bathtub hair clogs — it physically removes the blockage rather than just partially dissolving it.

Step 3: Baking Soda and Vinegar Flush

After removing the physical clog, flush with baking soda and vinegar to dissolve remaining soap scum and buildup:

1. Pour ½ cup of baking soda down the drain
2. Follow with ½ cup of white vinegar
3. Cover the drain and wait 20–30 minutes
4. Flush with hot water

Step 4: Plunger

If the drain is still slow, use a cup plunger. Fill the tub with a few inches of water to create suction, place the plunger over the drain, and plunge vigorously 10–15 times. Remove quickly to create suction. Repeat several times.

Step 5: Chemical Drain Cleaner

For stubborn clogs that don't respond to physical methods, Amazon Basics Max Strength Drain Cleaner Gel dissolves hair, grease, and soap buildup and is safe on all pipe types. Follow package directions and flush thoroughly with hot water afterward.

Prevent Future Bathtub Clogs

A drain hair catcher is the most effective prevention tool. This patented design fits over both pop-up and regular drains, catching hair before it enters the pipe. Clean after each use and bathtub clogs become a thing of the past.

Final Thoughts

Bathtub drain clogs are easy to clear with the right approach. Start by removing the stopper and clearing visible hair, use a drain snake for deeper clogs, flush with baking soda and vinegar, and install a hair catcher to prevent future blockages.
