Step 8 · Install Remodel Plate and Trim
Once you are confident there are no leaks, you can install the new faucet trim. On the shower side, slide the large remodel plate (or escutcheon) over the valve stem. This plate is designed to cover the old hot and cold handle holes. Secure it to the wall or valve body according to the manufacturer's instructions, often with long screws. Apply a thin bead of silicone caulk around the top and sides of the plate, leaving the bottom open to allow any moisture to escape. Slide on the handle and secure it with its set screw. Install the new tub spout and shower head.
