The enclosure includes an outer frame having a generally open rectangular configuration with spaced apart elongate top and bottom bars, and a pair of spaced apart elongate side bars extending between the top and bottom bars. The bars of the outer frame define a central space therebetween. The bottom bar is designed for attachment to the top of a side wall of a bathtub. The top bar is designed for attachment to a ceiling structure above the side wall of the bathtub. A first of the side bars is designed for attachment to a wall structure adjacent one end of the bathtub. A second of the side bars is designed for attachment to a wall structure adjacent another end of the bathtub. A pair of panels are provided in the central space of the outer frame. Each of the panels is extended between the top and bottom bars. One of the panels is positioned adjacent one of the side bars. Another of the panels is positioned adjacent another of the side bars.
