How to Install a Shower Faucet – DIY Guide
Troubled with a leaking shower faucet or faulty temperature control? There’s no need to call a plumber just yet. Installing the shower faucet is actually not that difficult. Most homeowners can change a shower faucet on their own to save on labor fees.
When purchasing a new shower faucet, keep in mind the measurements and style of the one needed to be installed. It is easier to install or change a shower faucet when the style is the same and the measurements are accurate.
Faucets basically have three styles: Single-handled faucets have one handle to control the temperature and water flow. Two-handled faucets have different handles for hot and cold water temperature while three-handled faucets have three handles to control hot and cold water and divert the water to the showerhead.
Aside from the new faucet parts, there are only a few tools needed to change a shower faucet. Prepare a small flathead screwdriver, a Phillips screwdriver, a pair of Slip-jaw pliers and an adjustable wrench. For those with two-handled and three-handled faucets, also prepare some petroleum jelly and Teflon tape.

Step 2: Remove the Plastic Cover
