Abstract: An apparatus for insertion within a bathtub defined by spaced parallel side walls, a floor coextensive with the side walls, and a rear wall mounting a cushion at an upper terminal end thereof directed orthogonally between the side walls. The side walls are pneumatically or fluidly filled within chambers formed in the side walls, wherein the floor includes a chamber for filling overlying a lower chamber filled with a granular material to effect stable positioning of the organization in use. Suction cup members are mounted coextensively along the floor, side walls, and cushion for securement to an interior surface of an associated bathtub.
