Step 2 · Remove Old Faucet Trim
From inside the shower, remove the visible parts of the old faucet. Start by prying off the decorative caps on the handles with a small flathead screwdriver or utility knife. This will expose a set screw, which can be removed with an Allen wrench or Phillips screwdriver. Pull the handles straight off. Next, unscrew the escutcheons (the chrome flange plates behind the handles). They may be threaded on or held by screws. If they are stuck, you may need to carefully cut the old caulk seal with a utility knife. Finally, unscrew the tub spout. If it doesn't unscrew, it may have a set screw on the underside that needs to be loosened.
