Our wood medicine "box" hangs on a stud behind the wallboard. We added a few shelves, then covered the box with a hinged mirror. (Actually, a big mirror we already owned that was more frame than mirror; so, we cut the frame down to fit its new space.) The result: we've got lotion, razors, medicine, those toothbrushes and lots more tucked out of the way but right where we need them.
