How to Install a Single Handle Tub and Shower Faucet

What You'll Need
Needle Nose Pliers
New Faucet

Installing a single handle tub and shower faucet is a simple project that you can complete without the need for paying costly professionals. Single handled tub and shower faucets have less connections and moving parts than those with multiple handles and can easily be replaced and installed. 

Step 1 – Shut Off the Water 

The first step in installing or replacing a single handle tub and shower faucet is to turn the water off. Access the main water shut off for your home, which should be located next to the outside water meter, and turn the water to your home off completely. Now turn on the water on at a sink to release the pressure from the water lines and pipes. This will prevent you from having water leak pouring out during your installation process. 

Step 2 – Remove Old Faucet 

If you have an existing faucet, you need to remove the old faucet. Single handled faucets utilize a single screw to secure them into place. Some screws may be found at the bottom of the faucet and can be easily unscrewed. Some faucets have a screw hidden beneath a cap or cover. In this case, you need to remove the cover or cap to access the screw. Use a flat heard screwdriver to pry off the cap or cover, exposing the screw. Once you can access the screw, unscrew it. After removing the securing screw, pull the handle and escutcheon plate forward to remove the old faucet from the faucet valve and expose the metal sleeve of the faucet. 

Step 3 – Remove Sleeve, Clip and Cartridge 

Next, you need to remove the metal sleeve by pulling it out and away from the wall. After you have removed the metal sleeve, you should be able to see a clip located at the top of the faucet valve. Using the needle nose pliers, carefully pull the clip out of the valve, taking care not to bend or break the clip. Now you can completely remove the faucet cartridge from the wall. 

Step 4 – Install Cartridge, Clip and Sleeve 

Now you can start to install your new faucet by installing the new faucet cartridge over the faucet valve. Once in place, secure the faucet cartridge by installing the clip back into the faucet value where you previously removed it. Now you can install the metal sleeve by pushing it back into the wall much in the opposite manner of how you previously removed the metal sleeve. 

Step 5 – Install the New Handle 

Now you can slide the new handle over the faucet valve into place. To secure the handle, use the provided screw and tighten the screw securely to hold the handle. If your new handle came with a cap or cover, snap the cap into place to conceal the screw. 

Step 6 – Restore the Water 

Now your single handle tub and shower faucet is installed and ready for use. You can restore the water to your home and test your new faucet.
