I have the side bath and like it... I can close off hallway just in front of bathroom if I want with a curtain rod that I hung across opening. My large wardrobe cabinet is in hall directly across from bathroom.
I like the fact that I can contain humidity from shower in the bathroom. I can't imagine dealing with the steam from a shower in the bedroom, would think it would cause all sorts of issues with everything stored in there. I guess if you live in a dry climate, it might not be an issue, but here in GA humidity is always a major concern.
