Abstract: A portable shower stall, for allowing a person to bathe while seated in a wheelchair, for temporary installation in a kitchen having a sink having a basin and a hand sprayer. The shower stall has a frame having side panels and a rear panel that are selectively foldable, a top rail and a lower rail. A base tray extends below the frame and collects waste water. A curtain extends downwardly from the top rail and directs waste water into the base tray. The base tray has a front flap that selectively lowers to allow the person to roll the wheelchair into the base tray between the side walls and rear wall to bathe using the hand sprayer, while a pump returns waste water from the base tray to the basin.
