摘要

The bathtub has a groove (1) adapting to a shape of a door (2), and a hollow type inflatable joint (3) housed in the groove. The joint is fixed on an inner flank of the groove for opening the door towards an exterior or on an outer flank for opening of the door towards an interior, where the joint is pressurized and plated against the door to make the door waterproof. A pipe connects two ends of the joint and permits a pressurized liquid to penetrate into the joint for inflating or for removing the joint to evacuate the liquid from the joint to deflate the joint.
