Sitting bathtub constituted by a tub (10) provided with an opening (11) extending almost down to the bottom of the tub and a hatch (15) to close this opening. When closing the bathtub before having a bath the hatch (15) is placed on the inside of the bathtub and the hydrostatic forces of the water forces the hatch against the edges of the opening where a seal is provided on the hatch. The sides and in particular the side with the opening are inclined or sloped outwards from the bottom so that the hatch with its seal will rest by its own weight against the seal. In particular seal (16), hatch (15) and the side of the bathtub are so arranged that a good sealing effect is always certain at the bottom of the bathtub when the rising water and the resulting hydrostatic pressure enable the sealing effect to climb upwards even on a light and slightly flexible hatch. This in turn enables the hatch to be very light and easy to handle and it is thus no inconvenience to have a loose hatch. The hatch is suitably transparent or clear.

A bathtub having a bottom and a surrounding side wall which together from an open-topped container having an upper edge, the side wall and upper edge having an opening through which a person may enter and leave the bathtub, a separate, manually maneuverable hatch which is free of connection to the bathtub so as to be selectively placed inside and outside the bathtub by the user, said hatch having an upper edge provided with an inverted U-shaped edge capable of hooking over and contacting the edge of the bathtub and allowing play toward and away from said side wall, said hatch having dimensions greater than the dimensions of said opening so that when placed inside the bathtub the edge portion of said hatch overlies the edge portion of said opening whereby said hatch covers said opening; a seal between the edge portion of said hatch and the edge portion of said opening, said hatch and bathtub being so shaped that upon mounting said hatch inside said bathtub in overlying relationship to said opening sufficient sealing contact is obtained initially at the lower edge of said opening to close a gap which exists between said edge portion of said opening and said seal so that water when entering the bathtub exerts further pressure on said hatch, which pressure successively extends upwards as the water rises in the bathtub thereby completing sealing of the edge portion of said hatch to the edge portion of said opening.
