I want to install this square floating cabinet on my walls, but it's small, so I will only be able to hit one stud with it. If I add a wall anchor to the other side, will it be strong enough? Or will the cabinet will just fall?? What should I do then? Thanks, I tried looking for an answer but I can't find it anywhere.
Hang a piece of 1/2" to 3/4" birch plywood (depending on how strong you need it to be), the same dimensions as the cabinet, on the wall, securing it with counter sunk #10 or larger screws, at the stud, and countersunk toggles at the corners.
Hang your cabinet from the plywood, and stain/paint the plywood to match.
If you don't want to see the plywood grain, you can cut it a little narrow, and glue hardwood edge banding to it, and then stain/paint to match.
