Step 2 · Gain Access to the Valve

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

To access the valve, you must create an opening in the wall. First, remove the old handles and trim plate (escutcheon). Use a stud finder to locate the studs on either side of the valve. Mark a rectangular cutting area around the valve that is large enough to work in, typically about 12x12 inches. If working with tile, use an angle grinder with a diamond blade to carefully cut along your marked lines. Go slow to avoid cracking adjacent tiles. Once the tile and underlying backer board are cut, use a pry bar to gently remove the section and expose the old valve and surrounding pipes.
