Step-by-Step Guide to Replacing a Bathtub Faucet Stem
Step 1: Turn Off the Water Supply
Before starting, turn off the water supply to prevent leaks or flooding. Locate the main shut-off valve in your home and turn it off. Then, open the faucet to drain any remaining water.
Step 2: Remove the Faucet Handle
- Use a flathead screwdriver to pry off the handle’s decorative cap.

Step 5: Install the New Faucet Stem
- Apply plumber’s grease to the new stem to ensure smooth operation.
- Insert the replacement stem into the fixture and tighten it using the adjustable wrench.
- Ensure the stem is secure but avoid overtightening.
Step 6: Reassemble the Faucet
- Reattach the escutcheon plate and ensure it sits flush.
- Reinstall the faucet handle and secure it with the screw.
- Snap the decorative cap back into place.
Step 7: Turn On the Water Supply and Test
