Inflatable bathtub

Abstract

An inflatable bathtub which enables efficient use of water and space. The bathtub also provides comfort and ease of use with respect to e.g. cleaning, storing, filling with water, emptying, carrying and moving. The bathtub comprises upright side walls consisting of inflatable side tubes. The side tubes at least partly extend around the circumference of the bathtub in a horizontal plane. The bathtub further comprises a bottom section attached to the bottom side on the side walls. At least a part of the outside of the side walls is curved inwardly in the horizontal plane. The side walls, being up to a certain level flexible, but in a way biased in an inward direction, are forced in an outward direction. The inward bias and the outward pressure by the water results in a straitening of the walls or any other predetermined shape of the side walls.
