A faucet escutcheon is the decorative plate located between the wall and the faucet and handles. Removal of this decorative plate is moderately easy and requires a few simple tools and steps.
Step 1 - Turn Off Water
Locate the water valve and turn it counterclockwise to shut off the water.
Step 2 - Remove Faucet and Handles
Now you need to remove the handle and faucet itself. Take a screwdriver and remove the decorative piece on the faucet handle that hides the main screw. Unscrew the handle and detach it from the wall and faucet.
Step 3 - Remove the Escutcheon
Escutcheons are attached either with screws or caulking. To remove a escutcheon attached with screws, simply take a screwdriver and unscrew from the wall. To remove one that is attached with caulking, take a plastic putty knife and gently cut through the caulking to lift the plate away from the wall.
It is important to always use a putty knife when removing a escutcheon attached by caulking. Using an improper tool can result in damage to the mounting surface.
