I bought a 15 inch wide medicine cabinet for a bathroom that I was intending just to fit between the studs but this is going to make it a little to close to the shower. So I am toying with cutting out a stud but I won't do so till I'm convinced the house will not fall down!
The wall in question is only 4 feet from the exterior wall. It is on the second floor a a two store condo. There are several beams (but not near this stud that go perpendicular to the wall). The wall is parallel to the sides of the house and perpendicular to the front door.
There is a shower stall installed on the same side as the wall. The wall in question is to the left on the pictures.
