How to Replace a Bathtub Handle Stem

A worn-out or leaking bathtub handle stem can cause frustration and inconvenience. Replacing the stem is a relatively simple plumbing repair that can be completed in a few steps. Here's a comprehensive guide on how to replace a bathtub handle stem.

Tools and Materials Needed

Replacement bathtub handle stem
Adjustable wrench
Screwdriver (Phillips or flathead, depending on the handle type)
Plumber's putty (optional)

Step 1: Turn Off the Water Supply

Before you begin working on the handle, turn off the water supply to the bathtub. Locate the shut-off valves under the sink or behind the bathtub and turn them clockwise to close them.

Step 2: Remove the Handle

Use the screwdriver to remove the screws that hold the handle in place. Once the screws are removed, gently pull the handle off the stem.

Step 3: Unscrew the Packing Nut

Beneath the handle, you will see a packing nut. Use the adjustable wrench to loosen and remove the packing nut.

Step 4: Remove the Stem

Grip the stem with the adjustable wrench and turn it counterclockwise to remove it.

Step 5: Apply Plumber's Putty (Optional)

Before installing the new stem, apply a thin layer of plumber's putty around the threads of the stem. This will help create a watertight seal.

Step 6: Install the New Stem

Insert the new stem into the hole and turn it clockwise to tighten it. Avoid overtightening.

Step 7: Install the Packing Nut

Replace the packing nut and tighten it using the adjustable wrench. Ensure that the packing nut is snug but not too tight.

Step 8: Reattach the Handle

Place the handle back onto the stem and secure it with the screws you removed earlier.

Step 9: Turn on the Water Supply

Open the shut-off valves to turn the water supply back on. Check for any leaks and adjust the packing nut as needed.

Congratulations!

You have successfully replaced the bathtub handle stem. If you encounter any difficulties or the leak persists, it is advisable to seek professional help from a licensed plumber.
