This bathtub is designed to support your knees and conserve water. I like the idea, but I wonder about two possible problems: (1) if two people are in the tub facing each other, it could get awkward getting both sets of legs comfortable; (2) I like to occasionally slide my body down to submerge my entire head, and with this tub I can’t.

IdeaSpark*: a proposed solution addressing both problems: Manufacture just the peak (a large triangular wedge) out of a material that won’t float. Make different sizes, then anyone can buy one to use in their regular tub. Slide it down to submerge your head; remove it to make room for your partner. Bonus: way less expensive.
