Not sure if this is the right section to post in...but we want to make a sort of wet room and wondered if anyone had done anything similar? Or used any of the kits people use for home wet rooms in their boat?
But that said, most catamarans I've seen (and the one I own) are done that way. The floor is/has a sump with a grid to stand on. The walls are caulked, as is the floor. The sink faucet is a pull-out showerhead.
