Abstract: A shower stall booth is converted into a bath by supporting an integral sheet of waterproof material against the upstanding walls of the shower stall. Support components extend across the open side of the shower stall to further support the waterproof sheet. A second embodiment enables the waterproof insert to extend outward from within the stall shower to any desired length and breadth. A third embodiment enables the waterproof tub insert to extend upward to any desire height. Fourth and fifth embodiments accomplish the shower stall bath conversion by means of affixing either a watertight wall or a partial tub insert to the open side of the shower stall.
