How To Replace A Bathtub Shower Faucet
Bathtub and shower faucets are essential fixtures in the bathroom, controlling the flow and temperature of water in your bathtub and shower. Over time, these faucets may become worn, leak, or deteriorate, necessitating replacement. Learning how to replace a bathtub and shower faucet yourself can save you money on plumbing service and give your bathroom a brand new look.
1. Tools and Materials You’ll Need
Before starting, prepare the following:
Adjustable wrench
Screwdrivers (flathead and Phillips)
Allen wrench (for set screws)
Plumber’s tape
Replacement Bathtub Shower Faucet (with matching trim kit)
Bucket and towel for water collection
2. Turn Off the Water Supply
Locate the shut-off valves near the bathtub or turn off the main water supply.
Open the faucet to release any remaining water pressure.
3. Remove the Old Faucet Handle and Trim
Use a screwdriver or Allen wrench to remove the handle’s set screw.
Gently pull off the handle.
Unscrew the escutcheon plate (decorative trim around the faucet) and remove it.
Keep all screws in a safe place for reassembly reference.
4. Remove the Old Cartridge or Valve
Depending on your faucet type (single-handle or two-handle), remove the old cartridge, stem, or valve using a wrench.
Inspect the valve body for mineral deposits or damage. Clean if necessary.
5. Install the New Cartridge or Valve
Insert the new cartridge or valve into the valve body.
Ensure it is aligned correctly (hot and cold sides must match).
Tighten it securely but avoid over-tightening.
Apply plumber’s tape on threaded connections to prevent leaks.
6. Reattach the Trim and Handle
Replace the escutcheon plate and secure it with screws.
Slide the handle back into position and tighten the set screw.
Ensure the handle moves smoothly for both water flow and temperature control.
7. Restore Water Supply and Test
Turn on the main water supply or shut-off valves.
Slowly test the faucet by turning the handle(s).
Check for leaks around the valve, handle, or connections.
Make adjustments if necessary.
8. Final Tips
Always purchase a replacement faucet kit compatible with your plumbing system.
If the valve body itself is corroded or damaged, you may need professional help to replace it inside the wall.
Regular cleaning and maintenance extend the lifespan of your new faucet.
