Abstract: An improved closure for use in a space at the upper portion of a stall area for a bath, shower, spa or the like, to provide an humidity and heat barrier. A foldable thin sheet of material is supported by a framework mounted in the upper portion of the stall area. The framework is designed to be supported in the upper portion of the stall by urging against or securing to two opposing walls. A highly flexible material, such as a thin vinyl sheet or a fabric sheet, is chosen for the foldable sheet. The flexible sheet is supported by the framework in an inverted V-shaped arrangement.
