Abstract: An auxiliary bathtub mounted above a conventional bathtub for use by invalids. The bathtub includes a rectangular frame approximating the shape of the conventional bathtub formed by a pair of parallel end walls and side walls. A flexible, waterproof liner extends between the side and end walls and along the inside faces thereof to form a watertight container. At least one of the side walls pivots downwardly to allow entry and exit from the tub. The pivoting side wall is held in its upright position by a releasable latching mechanism actuated through a release cord extending along the outside face of the side wall. A planar seat extends across one end of the tub beneath the liner to support the bather.
