Splinter Works, a UK-based design studio, has created what I think is safe to call the first hammock-inspired bathtub. They've basically taken the ability of carbon fibre sheeting to form almost any shape and remain infinitely-strong and built the tub out of it. 2.7 meters long and mounted on 2 stainless-steel brackets, which can be hidden if desired it's not entirely functionless form, the thick foam center insulates the tub, keeping the hot water hot longer. The optimal setting would be in a wet-room with the center-mounted drain of the tub just suspended over a drain in the floor, but they'll deign to provide a drain-pipe if needed.
ps. neither the diaphanously-robed model nor the faux-Pollock come with.
