Step 8 · Repair the Wall
Once you have confirmed there are no leaks, you can close up the wall. The simplest method is to use a remodel plate or cover plate. These are specifically designed to cover the large opening and the old handle holes, providing a clean, finished look. Place the foam gasket (if included) on the back of the remodel plate, position it over the opening, ensuring the hole for the new valve stem aligns correctly. Secure the plate to the wall or to the wood blocking using the provided screws. Apply a bead of 100% silicone caulk around the entire perimeter of the plate to create a waterproof seal against the tile wall.
