any one good at bathroom layout? I am needing to layout design for a bathroom in my basement. Problem is, the main a/c-furnace air and return air duct work will run through half of it. There for minimizing head height on one half of the bathroom. Also there is no roughed in plumbing in the floor. So either I would have to jack hammer out or do a false floor. I would much rather stay away from breaking out the concrete. The room will be 11'x12'
