A bathtub that fills with water during a shower usually means you have a clogged drain. Hair, soap scum, and other debris can build up over time, slowing the water flow. Start by removing any visible hair and try pouring hot water down the drain. If that doesn’t work, use a plunger or a drain snake to clear the blockage. For stubborn clogs, consider using a drain cleaner or calling a plumber.
Ever stood in the shower and noticed the water creeping up your ankles? It’s a common problem! A bathtub that fills up while you’re showering is usually a sign of a clogged drain. It’s annoying, but don’t worry, it’s often a simple fix.
We’ll walk you through easy steps to clear that drain and get your shower back to normal. You’ll learn how to identify the cause, use simple tools, and even prevent future clogs. Let’s get started!
Why Does My Bathtub Fill With Water When I Shower?
The most common reason your bathtub fills with water when you shower is a clogged drain. Here’s a more detailed breakdown of potential causes:
- Hair: This is the number one culprit. Hair easily binds with soap and grease, forming stubborn clumps that restrict water flow.
- Soap Scum: Over time, soap scum builds up on the drain walls, narrowing the pipe and slowing drainage.
- Mineral Deposits: Hard water can leave mineral deposits inside the drainpipe, gradually reducing its diameter.
- Small Objects: Items like small toys, shampoo caps, or pieces of soap can accidentally fall into the drain and cause a blockage.
- Grease and Oil: Pouring grease or oily substances down the drain can solidify and create a sticky trap for other debris.
- Pipe Issues: In rare cases, the problem might be a more serious issue like a collapsed or misaligned drainpipe.
Tools You’ll Need
Before you start unclogging your drain, gather these essential tools:
- Rubber Gloves: Protect your hands from bacteria and harsh chemicals.
- Plunger: A standard cup plunger is usually sufficient for bathtub drains.
- Drain Snake (or Auger): This flexible tool helps you reach deeper into the drain to break up or remove clogs.
- Screwdriver: You might need this to remove the drain cover.
- Bucket: To catch any debris or water you pull out of the drain.
- Old Cloths or Towels: To wipe up spills and protect the surrounding area.
- Baking Soda and Vinegar: A natural alternative for dissolving minor clogs.
- Hot Water: For flushing the drain after each step.
Step-by-Step Guide to Unclogging Your Bathtub Drain
Follow these steps to get your bathtub drain flowing freely again:
Step 1: Remove Visible Hair and Debris
Start by inspecting the drain opening. Use your gloved hands or a pair of tweezers to remove any visible hair, soap scum, or other debris. This simple step can often solve minor clogs.
Pro Tip: A bent wire hanger can also be useful for grabbing debris from the drain.
Step 2: Flush with Hot Water
Pour a pot of boiling water down the drain. The hot water can help dissolve soap scum and loosen minor blockages. Be careful when handling boiling water to avoid burns.
Important: Avoid using boiling water if you have PVC pipes, as the high temperature can damage them. Use hot tap water instead.
Step 3: Use a Plunger
If hot water doesn’t do the trick, try using a plunger:
- Make sure there’s enough water in the tub to cover the cup of the plunger. If not, add some water.
- Position the plunger over the drain opening, ensuring a tight seal.
- Push and pull the plunger up and down vigorously for several minutes.
- Remove the plunger and see if the water drains. If not, repeat the process.
Step 4: Try Baking Soda and Vinegar
This natural solution can help dissolve clogs without harsh chemicals:
- Pour one cup of baking soda down the drain.
- Follow with one cup of white vinegar.
- Let the mixture fizz for 30 minutes.
- Flush with hot water.
Why it works: The chemical reaction between baking soda and vinegar creates carbon dioxide, which can help break down the clog.
Step 5: Use a Drain Snake
A drain snake is a flexible tool that can reach deeper into the drainpipe to break up or remove clogs:
- Insert the end of the drain snake into the drain opening.
- Push the snake down the drain, rotating it as you go.
- If you feel resistance, continue rotating the snake to break up the clog.
- Once you’ve reached the clog, pull the snake back out, removing the debris.
- Flush the drain with hot water.
Step 6: Check and Clean the Drain Stopper
Sometimes, the clog is located right at the drain stopper. Remove the stopper and clean off any accumulated hair or debris. There are different types of stoppers, so here’s how to handle a few common ones:
- Lift-and-Turn Stopper: Unscrew the stopper by twisting it counterclockwise.
- Pop-Up Stopper: These usually lift straight out, but some may require you to twist and pull.
- Toe-Touch Stopper: These often have a screw that needs to be loosened before you can remove them.
Step 7: Consider a Chemical Drain Cleaner (Use with Caution!)
If all else fails, you can try a chemical drain cleaner. However, use these products with caution, as they can be harmful to your pipes and the environment.
- Follow the instructions on the product label carefully.
- Wear gloves and eye protection.
- Ensure the area is well-ventilated.
- Avoid mixing different drain cleaners, as this can create dangerous fumes.
Important: Only use chemical drain cleaners as a last resort. Repeated use can damage your pipes.
Step 8: Call a Plumber
If you’ve tried all the above steps and your bathtub is still filling with water, it’s time to call a professional plumber. There might be a more serious issue, such as a collapsed drainpipe, that requires specialized equipment and expertise.
Preventing Future Clogs
Prevention is key to keeping your bathtub drain clear. Here are some tips to help you avoid future clogs:
- Use a Drain Screen: Place a drain screen or hair catcher over the drain opening to catch hair and other debris before they enter the pipe.
- Regularly Flush the Drain: Pour hot water down the drain once a week to help dissolve soap scum and prevent buildup.
- Avoid Pouring Grease Down the Drain: Dispose of grease and oily substances in the trash instead of pouring them down the drain.
- Clean the Drain Stopper Regularly: Remove and clean the drain stopper every few weeks to remove accumulated hair and debris.
- Consider Enzyme Drain Cleaners: These eco-friendly cleaners use enzymes to break down organic matter and prevent clogs.

FAQ
Why does my bathtub drain slowly even after I plunge it?
A slow draining tub after plunging can mean the clog is only partially cleared, or there’s buildup further down the drainpipe. Try using a drain snake to reach deeper and remove any remaining debris.
Can I use a toilet plunger on my bathtub drain?
While you can technically use a toilet plunger, a cup plunger is better suited for bathtub drains because it creates a tighter seal on the flat surface.
Are enzyme drain cleaners safe for all types of pipes?
Yes, enzyme drain cleaners are generally safe for all types of pipes, including PVC and metal pipes. They are a gentle and eco-friendly alternative to chemical drain cleaners.
How often should I clean my bathtub drain?
You should clean your bathtub drain at least once a month to prevent clogs from forming. Regular cleaning will help keep your drain flowing smoothly.
What are the signs of a more serious plumbing problem?
Signs of a more serious plumbing problem include recurring clogs, foul odors coming from the drain, and water damage around the bathtub. If you experience any of these issues, it’s best to call a plumber.
Can hard water contribute to bathtub drain clogs?
Yes, hard water can contribute to bathtub drain clogs. The minerals in hard water can build up inside the drainpipe, gradually reducing its diameter and slowing water flow. Consider using a water softener to prevent mineral buildup.
Is it safe to pour boiling water down a PVC drain?
No, it’s not safe to pour boiling water down a PVC drain. The high temperature can damage or warp the PVC pipes. Use hot tap water instead.
