A Bouncy Bath!

The Bathboard is a too-good-to-be-true design. It has all the makings of an excellent bathtub; one, which folds up and holds enough water for a good soak. But my only worry is that will the framework take the weight of water + the person using it? For the moment lets just consider this, the tub is made from foam rubber treated to be very elastic and spongy. It weighs less than 3 kgs and juts out only 12-cms from the wall. A flexible drainpipe starts above the central point of the tub, making it easy to fold up. So back again to my question, can we have this design workable for the cause of bathing luxury in limited spaces? If yes, then I surely want one.
