Step 3 · Remove the Escutcheon Plate and Sleeve
After removing the handle, you'll see a sleeve (often black plastic) and a large decorative plate called an escutcheon. First, pull the sleeve straight off; it may have a temperature limit stop on it that also pulls off. The escutcheon plate is typically held to the wall with two long Phillips head screws. Use a Phillips screwdriver to remove these screws. If the edge of the escutcheon was sealed with caulk, you may need to carefully run a utility knife around the perimeter to break the seal before pulling it away from the wall. Behind the plate, you will see the main valve body embedded in the wall.
