Medicine cabinet

You are going to have a tough time putting a cabinet in a wall that doesn't have an opening already framed in it. It may be possible to mount it to the wall but that would depend on where you want it and where the wall studs (if any) are located.

Personally I would go with a surface mount and not a recessed mount

Id agree with Tracker. I have no problem building a cabinet but for $45 its not worth my time and supplys. It is made out of MDF bit so is the rest of my TT cabinets. Make sure your screws when you install a cabinet are not to long. Im guessing around 1/34 with washers into the studs should be safe. You may need to add a extra magnet if door doesn't stay closed when traveling..

Good point.

My medicine cabinet is wall mounted from the factory and uses the exterior wall for the back of it. It has a mirror and two shelves. Works just fine, no need to be recessed into the wall.

Not sure I've ever seen a recessed mounted medicine cabinet in an RV. Surface mounts styles are a dime a dozen anywhere like Home Depot/Lowes or the internets.

I believe that if you tried to recess mount a standard medicine cabinet, it would be sticking out of the other side of the wall.
Lots of medicine cabinets at Lowe’s, HD, etc.
With the variety of wall anchors available, mounting shouldn’t be too difficult.

Recessed cabinet will be out of the question....as others have already suggested....RV walls are only about 2 inches thick.

Medicine cabinets are usually (always?) surface mounted. Below are a couple of photos of OP's Springdale, 2018 & 2016 models and show a med.cabinet above the vanity sink. Older models also appear to have a med. cabinet. No idea if these were original or added by the owner. Maybe the PO removed the cabinet and replaced it with a mirror?

Med. cabinets can also be added above the toilet (like ours). There's many sources of stock cabinets like Lowes, etc. If wanting something original looking and to match existing wood finish, may try a Keystone dealer and they could order one.
