  • Adjustable wrench
  • Screwdriver
  • Plumber’s tape
  • New tub faucet
  • Bucket or towel
  • Silicone caulk (optional)

2. Turn off the water supply

Before you begin any work, it’s crucial to turn off the water supply to avoid faucet leaks or water damage. Locate the shut-off valves near your tub and turn them clockwise until they’re fully closed.

3. Remove the old tub faucet

To remove the old tub faucet, follow these steps:

a) Remove the handles and trim

Use a screwdriver to remove any screws or bolts securing the handles and trim. Once removed, carefully pry off the handles and trim using a flathead screwdriver or a trim removal tool.

b) Unscrew the spout

Locate the spout beneath the faucet and twist it counterclockwise to loosen it. Once loose, pull the spout towards you to remove it completely.

c) Disconnect the water supply lines

Using an adjustable wrench, disconnect the water supply lines from the faucet. Place a bucket or towel beneath the connections to catch any remaining water.

4. Prepare the new tub faucet

Before installing the new tub faucet, it’s essential to prepare it properly. Here’s what you need to do:

a) Apply plumber’s tape

Wrap a few layers of plumber’s tape clockwise around the threads of the new faucet. This will create a tight seal and prevent any leaks.

5. Install the new tub faucet

Now it’s time to install the new tub faucet. Follow these steps:

a) Connect the water supply lines

Using an adjustable wrench, connect the water supply lines to the corresponding connections on the new faucet. Ensure they’re securely tightened but avoid overtightening, as it may damage the connections.

b) Install the new spout

Slide the new spout onto the faucet pipe and twist it clockwise to tighten it. Make sure it’s firmly in place.

c) Attach the handles and trim

Place the handles and trim over the faucet stems and secure them with screws or bolts. Ensure they’re aligned properly and snugly fitted.

6. Test the new tub faucet

With the installation complete, it’s important to test the new tub faucet for proper functionality. Turn on the water supply and check for any leaks or drips. If everything looks good, congratulations, you’ve successfully replaced your tub faucet!
