This area used to be a closet. I removed the paneling to turn it around to eliminate the ridges & found an old doorway. At least this door was removed & insulated. We have one in the back apartment that was just sided over from the outside, so the living room has a door to nowhere. Any ways this room makes more sense to me now, it was an entry. I just never understood why a 2400 square foot apartment had an 8 x 7 bathroom.
This is our floor choice it is an 18" peel & stick tile. I'd love to lay real tile but that will happen when we do the gut, mostly because we'll have to pull up the floor when we do the tub & toilet.
