Step 7 · Install Remodel Plate
Once you are 100% confident there are no leaks, turn the water off again and remove the test caps. Position the large remodel plate over the hole you cut in the tile, ensuring it completely covers the opening. Using a caulking gun, apply a bead of 100% silicone sealant to the back of the plate along the top and two sides. Do NOT apply sealant to the bottom edge. Press the plate firmly against the wall. The silicone will hold it in place and create a waterproof seal. Leaving the bottom open allows any moisture that gets behind the plate to weep out instead of being trapped in the wall.
