Portable and handicap accessible shower stall
Patent 8,302,219
A portable shower stall suitable for a wheelchair-bound person to bathe with the help of an assistant, comprising of a self-supporting flexible shower base, a modular shower enclosure standing freely within the shower base, a hand-held sprayer connected to a kitchen faucet via hose, and a pump with puddle scoop attachment that drains the shower base. One sidewall of the shower base can be pressed down and fastened to the shower base bottom to facilitate wheelchair access, but it can be released and restored to upright position for water retention. Shower enclosure consists of two identical bi-fold shower screens clamping to each other to form a splash-proof rectangle. However, one or both screens can be removed from the shower base to provide access to the wheelchair-bound person.
