How to Convert a 3-Handle Shower Faucet to a Single-Handle Valve · Step 3 of 9
In this video
To access the plumbing inside the wall, the user marks a rectangular area on the drywall around the pipes. He uses a stud finder to locate the studs and a level to draw straight lines. He then uses an oscillating multi-tool to cut along the marked lines and removes the piece of drywall.
Goal: Expose in-wall plumbing

FAQs
Given the 'intermediate' difficulty, what's the most challenging part of this conversion, and can I realistically finish it in 12 hours?
The most challenging aspects are accurately cutting and soldering copper pipes for the new valve, and then skillfully repairing the wall to a professional finish. While 12 hours is an estimate for experienced DIYers, expect it to take longer if you're new to soldering or drywall work, especially accounting for drying times for joint compound.
What are the essential safety precautions I must take when cutting and soldering plumbing, and opening up a wall?
Always shut off your home's main water supply completely before starting any plumbing work. When soldering, ensure good ventilation, wear eye protection, and keep a fire extinguisher nearby. Be extremely careful when cutting into the wall to avoid hidden electrical wires, gas lines, or other pipes.
The required tools list includes items like an awning and weatherstripping. Are these really necessary for this specific plumbing project?
Some items in the provided list, such as the awning, weatherstripping, and wall switch, appear to be irrelevant for converting a shower faucet. Focus on essential plumbing tools like a pipe cutter, reamer, soldering torch, copper fittings, flux, and solder, alongside basic carpentry tools for wall repair, and a drill/driver for mounting.
What's the most common mistake DIYers make when soldering copper pipes, and how can I avoid leaks?
A frequent mistake is not properly cleaning and fluxing the pipe ends and fittings before heating, which prevents a strong capillary bond. Ensure surfaces are shiny clean, apply flux evenly, heat the fitting (not the solder) until the solder flows into the joint, and avoid moving the joint until it cools to prevent pinhole leaks.
