Abstract
A bath chair has a base with a number of suction cups for rigidly attaching to the floor of a bath tub or shower stall. A stem to which a chair shell is attached is rotatably connected to the base. An improved swivel connector between the stem and the base is provided which comprises a rotator disk rigidly attached to the base. The upper surface of the disk is the supporting rotator surface. A hollow swivel cylinder is threaded into a central bore in the rotator disk and extends perpendicularly away from a surface of the rotator disk opposite the supporting rotator surface. A lid-shaped rotator shell is rigidly attached to the stem of the chair and has a rotator surface to be placed on the supporting swivel surface of the rotator disk. A cylindrical extension emanates perpendicularly from the rotator surface of the shell and fits snugly into the hollow swivel cylinder.
