Plan and Measure — Create an Access Panel
Part of project
How to Convert a 3-Handle Shower Faucet to a Single-Handle Valve · Step 2 of 10
In this video
The first step is to plan the installation. After confirming the need for an access panel to reach the bathtub plumbing, unbox the new access panel. Use a tape measure to determine the exact dimensions of the panel. Then, measure the space within the wall studs to ensure the panel will fit correctly and that the opening will provide sufficient room to work on the plumbing components in the future.
Goal: Determine the location and size for the access panel

FAQs
Given this project's intermediate difficulty and 12-hour estimate, what core skills should a DIYer possess before attempting this shower valve conversion?
You'll need solid basic plumbing knowledge, including cutting pipes and making secure connections (soldering or PEX crimping). Experience with drywall repair, such as cutting, patching, taping, and mudding, is also essential for finishing the wall access. Patience and attention to detail are key to avoid leaks and ensure a professional finish.
Beyond common household tools, what specific specialized tools or equipment are absolutely necessary to successfully complete the plumbing and wall repair steps?
For plumbing, you'll need a pipe cutter (copper or PEX, depending on your choice), soldering torch and supplies or a PEX crimping tool, and a stud finder to locate framing. For wall repair, a utility knife for precise drywall cuts, a joint knife for mudding, and appropriate safety gear like eye protection and a dust mask are crucial.
What are the most critical safety precautions DIYers must take when working with water lines and opening up a shower wall?
Always shut off the main water supply to your home before starting any plumbing work. Use a non-contact voltage tester to check for hidden electrical wires before cutting into walls. Wear appropriate personal protective equipment, including safety glasses, gloves, and a dust mask, especially when dealing with old pipes or drywall dust.
What are the most common mistakes DIYers make during the re-plumbing phase of this conversion, and how can they be avoided to prevent costly leaks?
A common mistake is inadequate preparation of pipe surfaces or improper soldering/crimping, leading to leaks. Ensure all connections are clean, properly fluxed (if soldering), and fully seated. Another error is not adequately supporting the new valve within the wall; secure it firmly to framing to prevent movement and strain on the connections.
