Made from two layers of carbon fibre, with a foam core sandwiched between them for insulation to keep the water warm for longer, the Vessel from UK-based design firm Splinter Works is one of the most interesting bath tubs I’ve ever come across.

Designed for use in a wet room, and filled using a floor standing tap with the waste water released through the base into a floor drain, it is suspended from the walls and does not touch the floor at all. Yes, this is a bath that is also a hammock.
