Step 2 · Cut Wall Opening

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Place the washing machine outlet box against the drywall at your marked location and trace the outline of the box's body (not the wider faceplate). Use a level to ensure your traced lines are perfectly straight. With a drywall saw, carefully cut along the pencil lines. Start with a shallow plunge to make sure the area is clear of obstructions. Once you've cut all four sides, gently remove the piece of drywall to reveal the wall cavity.
