Why Is My Bathtub Faucet Leaking?
Before you fix the problem, it’s helpful to understand why it’s happening. The most common reasons for a leaky bathtub faucet include:
- Worn-out washers or O-rings
- Corroded valve seat
- Mineral build-up from hard water
- Faulty cartridge
- Loose parts or worn seals
A dripping faucet can waste up to 200 gallons of water per month. The sooner you repair it, the better.
Types of Bathtub Faucets
Knowing the type of faucet you have will help determine the right repair method:
1. Compression Faucet
- Uses washers that wear out over time
- Requires more manual turning
- Common in older homes
2. Cartridge Faucet
- Has a valve cartridge inside
- Easier to operate with a single handle or two separate handles
3. Ball Faucet
- Typically a single-handle design
- Contains a ball bearing for water control
4. Ceramic Disk Faucet
- Durable and modern
- Uses ceramic disks to control water flow
Each type has different repair methods, but the core principles are similar.
Tools and Materials You’ll Need
Gather the following before you start:
- Adjustable wrench or basin wrench
- Phillips and flat-head screwdrivers
- Allen wrench (if needed)
- Replacement parts (washer, O-ring, or cartridge)
- Plumber’s grease
- White vinegar (for cleaning)
- Towel or rag
- Bucket (to catch any water drips)
- Flashlight (optional)

Step-by-Step: How Do I Repair a Leaky Bathtub Faucet?
Ready to fix that faucet? Let’s go step by step.
Step 1: Turn Off the Water Supply
Before doing anything:
- Locate the shutoff valve for your bathtub.
- If there isn’t one directly for the tub, shut off the main water supply.
- Open the faucet to drain any remaining water.
- Place a towel or bucket below the faucet to catch drips.
Step 2: Remove the Faucet Handle
- Use a screwdriver or Allen wrench to remove the handle screw.
- If it’s stuck, gently wiggle the handle or use a handle puller.
- Once the handle is off, remove any decorative trim or escutcheon plate.
Step 3: Inspect and Replace the Washer or Cartridge
Now comes the important part.
If You Have a Compression Faucet:
- Unscrew the stem from the faucet body.
- Check the rubber washer at the bottom. If it’s cracked or worn, replace it.
- Replace the O-ring if it’s deteriorated.
If You Have a Cartridge Faucet:
- Pull out the retaining clip (use pliers).
- Remove the old cartridge using cartridge pullers if necessary.
- Insert a new matching cartridge, making sure it aligns properly.
Apply plumber’s grease to all new parts for longevity.
Step 4: Reassemble the Faucet
- Carefully put all parts back in reverse order.
- Ensure every part fits tightly but don’t over-tighten.
- Use a cloth to wipe away any debris or mineral build-up before replacing the handle.
Step 5: Test for Leaks
- Turn the water supply back on.
- Run both hot and cold water.
- Look for drips or leaks.
- If the leak is gone — congratulations!
When Should You Call a Plumber?
While many leaks can be fixed at home, there are times you should seek professional help:
- You can’t remove a stuck cartridge or valve.
- The leak continues after replacing parts.
- You see signs of pipe corrosion or mold.
- There are signs of a deeper plumbing issue, like low water pressure.
Don’t hesitate to contact a licensed plumber if things seem beyond DIY.
How to Prevent Faucet Leaks
Prevention is better than cure. Here’s how to avoid future leaks:
- Don’t overtighten the handles – It puts pressure on the washers.
- Clean your faucet regularly – Remove lime and calcium build-up.
- Install a water softener – Helps reduce mineral deposits.
- Check for small drips – Fix them before they worsen.
- Upgrade old hardware – Newer faucets are more efficient and leak-resistant.
