Why Is My Bathtub Draining Slowly?

Before jumping to solutions, it’s important to understand why your tub may be draining slowly. Some of the most common causes include:

• Hair and Soap Buildup – The number one culprit. Hair combines with soap scum to form sticky clogs near the drain.
• Foreign Objects – Jewelry, small toys, or chunks of bath products sometimes slip into the drain and cause blockages.
• Pipe Corrosion – In older homes, pipes may corrode or collect mineral deposits that restrict water flow.
• Drain Fitting Issues – Damaged or poorly sealed fittings can interfere with proper drainage.

Signs of a Clogged Tub Drain

Watch out for these red flags that indicate your bathtub drain is clogged:

• Water pooling during showers
• Gurgling noises from the drain
• A lingering bad odor in the bathroom
• Visible debris around the drain opening
• Tub takes longer than usual to empty

DIY Methods: How to Fix a Slow Draining Bathtub

Most slow drains can be fixed without calling a plumber. Here are some effective solutions you can try at home:

1. Plunger Method

• Remove the drain cover.
• Add a few inches of water to cover the plunger’s base.
• Seal the plunger over the drain and pump vigorously for 20–30 seconds.
• Remove and check if water drains smoothly.

2. Boiling Water Flush

• Boil a kettle of water.
• Carefully pour it down the drain in stages.
• Wait a minute between pours to allow buildup to loosen.

3. Baking Soda and Vinegar Remedy

This eco-friendly home remedy for slow draining tubs works well on mild clogs.

• Cover with a wet cloth and wait 10 minutes.
• Flush with hot water.

4. Manual Hair Removal

• Remove the drain stopper.
• Use gloves and a flashlight to pull out visible hair or gunk.
• For deeper clogs, use a bent wire hanger or drain snake.

5. Drain Snake or Auger

• Insert the snake into the drain and twist until you feel resistance.
• Break apart or pull out the clog.
• Flush with hot water to clear debris.

6. Wet/Dry Vacuum
