A clogged bathtub drain full of hair is one of the most frustrating household plumbing issues. Hair buildup blocks water flow, causes unpleasant odors, and leads to standing water that can damage bathroom flooring and create an unsanitary environment. Fortunately, there are effective methods to unclog bathtub drains that can save time, money, and effort without needing to call a plumber.
Understanding the Cause: Why Hair Clogs Bathtub Drains
Hair clogs form when hair strands bind with soap scum, dirt, and grease, creating a dense mass that sticks inside the drain pipes. Over time, these clumps harden and restrict water flow. Long hair, pet fur, and residue from bath products significantly accelerate this buildup. Regular maintenance and immediate attention to slow drainage are key to preventing full blockages.
Essential Tools and Supplies for Hair Clog Removal
Before starting the unclogging process, gather the following tools:
Drain snake or drain auger
Needle-nose pliers or tweezers
Wire coat hanger (for DIY methods)
Plunger
Boiling water
Baking soda and vinegar
Rubber gloves
Bucket and old towel
Drain cleaning brush
Drain cover or hair catcher (for prevention)
Method 1: Manual Hair Removal from the Drain
Step-by-Step Instructions:
1. Remove the drain stopper by twisting or unscrewing it, depending on the model.
2. Put on rubber gloves to protect your hands.
3. Use needle-nose pliers, tweezers, or a bent wire hanger to pull out visible hair clumps.
4. Insert a drain snake deep into the pipe to catch hidden hair masses.
5. Twist and pull the snake back carefully to avoid damaging the pipe.
5. Dispose of the hair and rinse the drain with hot water.
This manual method is one of the most effective for removing stubborn hair.
Method 2: Unclogging with Baking Soda and Vinegar
This natural drain cleaner works without harsh chemicals and is safe for most plumbing systems.
Instructions:
1. Pour ½ cup of baking soda directly into the dry drain.
2. Add 1 cup of white vinegar slowly.
3. Cover the drain immediately with a plug or cloth to force the reaction down.
4. Let the mixture sit for at least 30 minutes to 1 hour.
5. Flush the drain with boiling water to clear loosened debris.
This method dissolves soap scum and breaks down organic material like hair effectively.
Method 3: Using a Plunger to Dislodge Hair Clogs
Plungers are not just for toilets. A cup plunger can help break apart bathtub clogs.
Procedure:
1. Seal the overflow drain with a wet cloth to ensure pressure builds.
2. Fill the tub with enough water to cover the plunger cup.
3. Position the plunger over the drain and plunge vigorously for 20–30 seconds.
4. Test the drain. Repeat as needed.
If water begins to flow freely, the clog is broken up.
Method 4: Chemical Drain Cleaners (Use with Caution)
Chemical solutions can dissolve hair, but they can also corrode pipes with frequent use.
Recommendations:
Use only non-acidic, hair-specific drain cleaners.
Follow the manufacturer’s instructions precisely.
Avoid mixing chemicals with natural cleaners.
For severe clogs, one-time use of a reliable commercial cleaner may restore flow but should not be a regular solution.
Method 5: Remove and Clean the Drain Trap (Advanced DIY)
For those confident with DIY plumbing, removing the drain trap can help eliminate deep clogs.
Steps:
1. Place a bucket under the trap to catch water and debris.
2. Unscrew the trap using pipe wrenches or your hands, depending on fittings.
3. Clean out hair clumps and residue using a brush or pliers.
4. Reassemble and test the water flow.
This method is highly effective for repeated or deep hair clogs but may require moderate plumbing knowledge.
Prevention Tips to Keep Hair Out of Drains
An ounce of prevention saves gallons of trouble. Incorporate these habits:
Install a drain hair catcher or mesh screen.
Brush hair before bathing to reduce shedding in the tub.
Clean the drain weekly with boiling water to remove early buildup.
Use baking soda and vinegar monthly as a preventative flush.
Routine maintenance significantly reduces the chances of dealing with a completely clogged bathtub drain.
When to Call a Professional Plumber
Despite best efforts, some clogs are too deep or too stubborn to remove without help. Call a plumber if:
The drain remains slow after multiple attempts.
Strange noises or foul smells persist.
Multiple drains in your home are backing up.
Professional plumbing services can use hydro jetting or camera inspections to resolve serious blockages.
Conclusion
Unclogging a bathtub drain full of hair does not always require harsh chemicals or expensive plumbing bills. By using a combination of manual tools, natural cleaners, and smart maintenance, you can easily restore proper drainage and prevent future issues. Follow these methods consistently, and you’ll ensure your bathtub stays clean, functional, and free of odors.
