I am redoing my laundry and am needing some design help. The pics show the old setup which consisted of a hot water tank (in behind the closet door) next to a raised wahsroom (covering the rest of the wall). The entrance to the crawlspace was a 2'x2' cutout in the washroom itself. I need to come up with some way to have a crawlspace access, toilet/sink, and hot water tank. The toilet piping will also be run under the concrete.
