In the following sections, you’ll discover essential tips and insights that will guide you through the faucet replacement journey. From preparation to final touches, this overview will equip you with the knowledge needed to approach the project methodically and confidently, setting the stage for a successful bathroom upgrade.

Removing the Old Tub and Shower Faucets

Before beginning the removal of old fixtures, ensure the water supply to the tub and shower is completely shut off. This prevents any accidental flooding or water damage during the process. Open the faucet handles to release any residual water pressure in the pipes.

Start by removing the faucet handles. Depending on the model, handles may be secured with visible screws or hidden under decorative caps. Carefully pry off caps using a flathead screwdriver, then unscrew the handle. If the handle is stuck due to mineral buildup or corrosion, applying a penetrating lubricant and gently wiggling the handle can ease removal.

Next, remove the escutcheon plate (also called a trim plate), which covers the valve assembly. This usually involves unscrewing several screws around the perimeter of the plate. Use a putty knife or flat tool to gently pry the plate away from the wall if it is sealed with caulk. Take care not to damage the tile or wall surface.

To remove the tub spout, identify the type of attachment:

  • Threaded spouts: Rotate counterclockwise to unscrew.
  • Slip-on spouts: Look for a set screw underneath, loosen it with an Allen wrench, and slide the spout off.

If the spout is stuck, apply penetrating oil and tap lightly with a rubber mallet to loosen it.

Preparing the Installation Area

After removing the old faucets, inspect the plumbing and wall surface for any damage or corrosion. Ensure the valve assembly is intact and properly secured within the wall. It may be necessary to replace or repair plumbing components if leaks or deterioration are evident.

Clean the area thoroughly to remove old caulk, debris, and mineral deposits. Use a putty knife to scrape away old sealant, and wipe down surfaces with a mild cleaner. A clean and dry surface ensures proper adhesion of new fixtures and prevents mold growth.

Measure the distance between the valve stems and the wall surface to confirm compatibility with the new faucet assembly. Some modern faucets require specific spacing or adapters to fit correctly. Adjust or shim as necessary to maintain proper alignment.

Installing New Tub and Shower Faucets

Begin installation by attaching the new tub spout. For threaded spouts, wrap the pipe threads with plumber’s tape (Teflon tape) to ensure a watertight seal before screwing the spout onto the pipe. For slip-on spouts, slide it onto the pipe and tighten the set screw securely.

Next, install the new valve trim and handles. Align the escutcheon plate with the valve body and secure it to the wall with screws. Apply a bead of silicone caulk around the edges of the plate to prevent water from seeping behind the wall.

Attach the faucet handles to the valve stems. Tighten any securing screws and replace decorative caps if applicable. Confirm the handles operate smoothly and align properly.

Before restoring water supply, check for any installation instructions specific to your faucet model. Some units include cartridge inserts or require calibration to ensure proper temperature control and flow.

Testing and Final Adjustments

Once installation is complete, slowly turn the water supply back on and observe the faucet for leaks or drips. Test both hot and cold water flow through the handles and verify the diverter (if applicable) switches water between tub spout and showerhead correctly.

Look for any water escaping around the escutcheon plate or connections. Tighten screws or fittings as needed to eliminate leaks. If water pressure is low or inconsistent, check for debris in the aerator or cartridge and clean accordingly.

Make any final adjustments to handle tightness and alignment to ensure comfortable operation. Confirm that the faucet meets your expected performance standards before finishing the project.
