I have now favored v5. It is like v6, except the door doesn’t slide up as high. I don’t like the toilet bowl, sink, and bathtub so close together. The cabinet that v6 and v7 are based on is probably only available in Switzerland. Now we have considered stacking the washing machine and dryer without a cabinet, or maybe in an open shelving system if we find one. Opening and closing a cabinet door all the time, I think, is always annoying when doing laundry. Then v5 should fit well. I thank again very much for the effort.
