On bigger sailboat, bathtub/shower install
My boat is a 43'' sailboat and the manufacturer installed a bathtub in the aft head. Actually the idea of a bathtub in a 43'' boat boggles my mind. We have never used it as a bathtub. First we used it for storage then as a shower. Actually as a shower, it is very good--keeps the water contained. I imagine it would also work for washing clothes. The tub is fiberglass, fairly small (perhaps 4-5'' long). I imagine the manufacturer suspended the tub in mid air, then built the rest of the boat around it. Certainly no way to get that tub out except by cutting in pieces.
