Step 1 · Preparation and Planning

Begin by shutting off the main water supply to your home to prevent any water flow. Open a faucet on a lower floor to drain any remaining water from the plumbing lines. Protect the shower or tub floor with old towels or a drop cloth. Gather all your tools, the new single-handle valve kit, and the remodel plate so they are readily accessible. Carefully review the instructions that came with your new valve, paying close attention to the required setback depth from the finished wall.
