I actually am having my cousin's boyfriend price it out for me. He has made furniture in the past, nice stuff actually, so I gave him some pictures. I told him I would handle the heating and tubs, but he's gonna see what it would cost to put together the rack. This is the one I asked him for...
Only difference is that I asked for it to just fit the large tubs and to have two doors on the bottom that open out instead of folding down.
