Step 2 · Protect the Work Area
Place a thick towel or a rubber mat on the floor of the shower or tub. This serves two purposes: it protects the surface from being scratched or chipped if you accidentally drop a tool, and it will cushion the fall of the old shower head and arm. Also, place a smaller rag or cloth over the drain opening to prevent any small parts, like the old washer from the shower head or chunks of old tape, from falling down the drain and causing a clog.
