How To Install A Bathtub Shower Faucet

2025-09-09

Installing a new tub/shower faucet can freshen the look of your bathroom, improve water efficiency, and prevent leaks caused by aging or worn fixtures. While it may seem like a complex task, most homeowners and contractors can successfully complete the installation by using the right tools and following a step-by-step approach.


1. Tools and Materials You’ll Need

Before starting, prepare the following items:

  • New bathtub shower faucet set

  • Adjustable wrench and basin wrench

  • Screwdrivers (Phillips and flathead)

  • Plumber’s (PTFE) tape

  • Pipe cutter (if replacing supply lines)

  • Silicone caulk

  • Bucket and towels


2. Shut Off the Water Supply

  1. Locate the main water supply valve and turn it off.

  2. Open the old faucet to release any remaining water pressure.

  3. Place a bucket underneath to catch any water that may drain.


3. Remove the Old Faucet

  1. Detach the handle by removing the screw or set screw.

  2. Unscrew and remove the trim plate (escutcheon).

  3. Use a wrench to loosen and remove the existing valve or cartridge.

  4. Disconnect the spout and showerhead if they are being replaced.


4. Prepare the Plumbing Connections

  • Check the condition of the hot and cold water supply lines.

  • Replace or adjust pipes if necessary using a pipe cutter.

  • Wrap PTFE tape around threaded connections to ensure a watertight seal.


5. Install the New Valve and Trim

  1. Insert the new cartridge or valve assembly into the housing.

  2. Secure it tightly with a wrench, ensuring it aligns properly.

  3. Reattach the trim plate and handle.

  4. Seal around the escutcheon with silicone caulk to prevent water seepage.


6. Attach the Spout and Showerhead

  • Screw the new bathtub spout into place using plumber’s tape on threads.

  • Attach the shower arm and showerhead, tightening gently with a wrench.

  • Ensure all fittings are secure but avoid over-tightening to protect finishes.


7. Restore Water Supply and Test

  1. Turn the water supply back on gradually.

  2. Test hot and cold settings for proper mixing.

  3. Engage the diverter to check that water flows correctly between the spout and showerhead.

  4. Inspect for leaks around all connections.


8. Maintenance Tips After Installation

  • Run water for a few minutes to flush out any debris.

  • Check for leaks over the first 24 hours.

  • Clean the showerhead regularly to prevent mineral buildup.

  • Schedule routine inspection of washers and cartridges to extend faucet life.
