Cut Drywall for Access — Access the Plumbing
Part of project
How to Convert a 3-Handle Shower Faucet to a Single-Handle Valve · Step 3 of 9
In this video
To access the plumbing behind the wall, a section of drywall must be removed. Use a level and a pencil to mark straight cutting lines around the existing laundry box, extending to the center of the nearest wall studs on each side. Then, use an oscillating tool with a wood/drywall blade to carefully cut along the marked lines.
Goal: Remove drywall section
- Cutting to the center of the studs provides a solid surface for securing the new drywall patch later.
Used in this video
- Level (Level Type: Torpedo level) — Drawing straight, level lines for cutting the drywall.
- Pencil — Marking the cut lines on the drywall.
- Oscillating tool — Cutting out the section of drywall.

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.
