The shower stall includes a base wall spaced above the subjacent terrain by a plurality of supports. The corner posts extend through a number of the supports and include sharp tipped lower ends adapted to be forced into the subjacent ground for stabilizing the erected shower stall. The sidewalls and door of the shower stall include distributed openings which, in the illustrated embodiment, are in the form of louvers. A top wall may be provided overlying the shower space. Each of the top wall and base wall may be provided with air flow openings, the air flow openings of the base wall further permitting discharge of the shower water downwardly through the subjacent space to the subjacent ground.
