Common Causes of a Slow Draining Bathtub

Before diving into the solutions, it’s essential to understand the usual culprits behind a slow-draining bathtub. Here are some of the most common causes:

  1. Hair Buildup: Hair is the leading cause of clogged bathtub drains. It accumulates over time, creating a tangled mess that slows water flow.
  2. Soap Scum: Soap residue can mix with minerals in the water, forming a sticky buildup that narrows the drainpipe.
  3. Hard Water Deposits: Mineral deposits from hard water can accumulate inside pipes, reducing their diameter and impeding drainage.
  4. Foreign Objects: Small objects like shampoo caps, jewelry, or even toys can accidentally fall into the drain, causing blockages.

DIY Fixes for a Slow Draining Bathtub

Remember you can always refer back to our DIY drain cleaning tips if you need help and really don’t want to call a plumber just yet after you try a few methods.

1. Boiling Water

One of the simplest and most effective ways to clear minor blockages is with boiling water:

  1. Boil a kettle full of water.
  2. Slowly pour the boiling water down the drain in two to three stages, allowing it to work for a few seconds between each pour.

The hot water can dissolve soap scum and loosen up hair and other debris.

2. Baking Soda and Vinegar

This natural solution is great for breaking down buildup inside the drain:

  1. Pour a cup of baking soda down the drain.
  2. Follow with a cup of vinegar.
  3. Cover the drain with a plug and let the mixture sit for 15-20 minutes.
  4. Flush with hot water to clear away the loosened debris.

3. Plunger

A plunger can be very effective for dislodging blockages:

  1. Fill the bathtub with enough water to cover the bottom of the plunger.
  2. Place the plunger over the drain and push down firmly, then pull up sharply. Repeat several times.
  3. Remove the plunger and see if the water drains faster.

4. Drain Snake

A drain snake, or plumber’s auger, is perfect for reaching deeper clogs:

  1. Insert the drain snake into the drain and push it down until you encounter resistance.
  2. Rotate the handle to break up the clog or catch debris.
  3. Pull the snake out and dispose of any gunk you’ve retrieved.
  4. Flush the drain with hot water.

Preventive Measures

Once you’ve cleared your drain, keep it flowing freely with these preventive tips:

  1. Use a Drain Cover: Install a hair catcher over your drain to prevent hair and debris from entering the pipes.
  2. Regular Flushing: Periodically pour boiling water down the drain to dissolve minor buildups before they become problematic.
  3. Clean with Baking Soda and Vinegar: Monthly treatments with baking soda and vinegar can prevent soap scum and mineral deposits.
  4. Avoid Harsh Chemicals: Chemical drain cleaners can damage pipes over time. Stick to natural solutions whenever possible.
When to Call a Professional

If your drain remains slow despite your best efforts, it may be time to call a plumber. Persistent clogs could indicate more serious issues such as a blockage deep within the plumbing system or problems with the sewer line. Professional plumbers in Florida or Lake Orion have the tools and expertise to diagnose and resolve these complex issues.


A slow-draining bathtub is an inconvenience, but with the right approach, it’s a problem you can usually solve on your own. By understanding the causes, applying effective DIY fixes, and adopting preventive measures, you can keep your bathtub drain clear and enjoy those relaxing baths without any worries.
