Replacing old medicine cabinet with a new one. Space is just shy of 14-1/4 inches wide between two wall studs. Medicine cabinet could use another 1/8" to fit inside.
I am contemplating sanding down the inside wall stud surfaces to get a bit more space. I am also interested in knowing if one stud can be cut out and "sistered" back in place? The wall is parallel to the ceiling joists. The hole is framed in on 3 sides, except the bottom because of an outlet.
Is there a framing solution to this quandary? Or should I just sand the studs?
A viable alternative is to consider returning the cabinet, and buying a narrower one instead.
Or slightly modifying the new cabinet by shortening the top/bottom plates and any back panel so it fits the available space, and the 1/8" overhang becomes part of the opening (ie you don't have to faff around with hinges) This presumes its wood or similar, and not a blow-moulded plastic part.
Using power tools will shake up the wall a bit and sometimes cause the drywall nails to appear or cracks and things so you end up refinishing and repainting. So prepare for that.
You could use an orbital jigsaw and trim out what you need on each side so it's a nice easy fit without spreading the studs which might cause nail pops over time up and down them.
Or, if you are careful, a cut with a worm drive skillsaw starting with a plunge cut on each side but don't cut yourself doing this if you are not a tradesman.
Sanding would take forever.
If you don't mind exposing studs and what you need and are skillful at drywall repair and wood work, then you could just frame it as you need.
