How to Install a Plumbing Access Panel for Future Repairs · Step 3 of 7
In this video
Put on safety glasses and a dust mask for protection. Using an angle grinder equipped with a diamond blade, carefully cut along the inner marked line through the tile and the backer board behind it. Once the cut is complete, use a screwdriver or small pry bar to gently remove the cut-out section, exposing the old plumbing assembly within the wall.
Goal: Cutting
- Angle grinders create a significant amount of dust. Proper ventilation and dust collection (e.g., a shop vac held by a partner) are highly recommended.

FAQs
Is a stud finder absolutely necessary for this project, or can I just estimate where to cut?
A stud finder is highly recommended to accurately locate studs, electrical wires, and plumbing lines behind the drywall. While estimating might seem quicker, it significantly increases the risk of damaging essential infrastructure. Using a stud finder helps ensure you cut into a clear area, preventing costly and dangerous mistakes.
What should I do if I accidentally hit a pipe or electrical wire while cutting the drywall?
Immediately stop cutting. If it's a water pipe, turn off the main water supply to your house. If it's an electrical wire, shut off the corresponding circuit breaker at your main electrical panel. Do not attempt to repair it yourself unless you are qualified; contact a licensed plumber or electrician for professional repair before proceeding.
The project is rated 'beginner' and estimated at 4 hours. What makes it take that long, and is it truly beginner-friendly?
The 4-hour estimate accounts for careful planning, precise measurement and tracing, multiple test fits, cutting the drywall, and allowing adequate time for construction adhesive to cure. While the steps are individually simple for a beginner, patience and attention to detail are crucial for a clean, secure, and professional-looking finish. Rushing can lead to errors.
Can I use caulk or another type of adhesive instead of heavy-duty construction adhesive like Liquid Nails?
It is strongly recommended to use a heavy-duty construction adhesive as specified. Standard caulk or lighter adhesives may not provide the necessary bonding strength to securely hold the access panel frame to the drywall long-term. An inadequate adhesive could lead to the panel loosening or detaching over time.
