Workshop plan
Step-by-step instructions
1
Step 1
Use a stud finder and inspection opening to map studs, plumbing, wiring, blocking, and the full cavity depth.
2
Step 2
Do not cut until the cavity is confirmed clear; frame a level opening with the manufacturer’s required clearance.
3
Step 3
Build a sealed cabinet box with a back, shelves, and a track sized for the mirror-door weight.
4
Step 4
Install the track and anti-jump hardware, then adjust the door so it clears the face frame and cannot leave the track.
5
Step 5
Finish the wall returns, seal bathroom-facing edges, and test the door through its full travel.
Safety check
This is structural-adjacent work. Shut off power and water where applicable, inspect both sides of the wall, and consult a licensed professional if utilities, load-bearing framing, or code requirements are uncertain.
