Tools and Materials You'll Need:

  • Wall-mounted faucet kit
  • Adjustable wrench
  • Plumber's tape (Teflon tape)
  • Drill and hole saw
  • Screwdriver
  • Level
  • Measuring tape
  • Pencil
  • Pipe wrench
  • Bucket or towels (for catching water)

Step 1: Turn Off the Water Supply

Begin by turning off the water supply to the bathroom. Locate the shutoff valves under the sink or in the basement, and close them by turning them clockwise. Open the faucet to release any remaining water pressure and verify that the water is completely turned off.

Step 2: Remove the Old Faucet

If you're replacing an existing faucet, remove it by disconnecting the supply lines and unscrewing it from the wall. Use an adjustable wrench or pliers to loosen the connections. Be prepared for some residual water in the lines.

Step 3: Locate the Wall Studs

Use a stud finder to locate the wall studs where you intend to mount the faucet. Wall-mounted faucets need to be securely anchored to studs for stability. Mark the stud locations with a pencil.

Step 4: Mark the Faucet Placement

Hold the faucet against the wall at the desired height, ensuring it's level. Use a pencil to mark the locations of the mounting holes and the center of the water outlet on the wall.

Step 5: Drill Holes

Drill holes into the marked locations for the faucet mounting and water supply lines. If you're drilling into tile, use a tile drill bit. Insert wall anchors if the faucet kit doesn't include them.

Step 6: Attach Wall-Mounting Hardware

Attach the wall-mounting hardware (usually included with the faucet) to the wall using screws or bolts. Make sure it's level and securely fastened to the studs.

Step 7: Install the Faucet

Apply the plumber's tape to the threads of the faucet's supply line connections. Then, connect the supply lines to the faucet and tighten them with an adjustable wrench. Ensure they are secure but not over-tightened.

Step 8: Connect the Water Supply

Connect the supply lines to the shutoff valves, again using the plumber's tape. Turn on the water supply and check for leaks. If you spot any leaks, tighten the connections further.

Step 9: Apply Silicone Caulk (if needed)

To create a watertight seal and enhance the aesthetics, apply a bead of silicone caulk around the base of the faucet where it meets the wall.

Step 10: Test the Faucet

Turn on the faucet and check for proper water flow and any signs of leaks. Adjust the hot and cold handles as needed.


Installing a new wall-mounted bathroom faucet is a satisfying DIY project that can give your bathroom a fresh, modern look. By following these steps and taking your time to ensure proper installation, you'll have a functional and stylish addition to your bathroom that you can enjoy for years to come. Remember, if you ever feel unsure about any part of the installation process, it's always a good idea to consult a professional plumber to ensure everything is done correctly and safely.
