Abstract
Abstract Rollers are rotatably affixed to the bottom of a housing. A sunken bathtub is mounted in the housing and extends from the top thereof. A pair of openings are provided in the top of the housing at opposite ends thereof. Each of a pair of shafts is positioned vertically in and extends through a corresponding one of the openings. A pair of guide devices for the shafts are provided in the housing. A support rod is affixed at its ends to the upper ends of the shafts outside the housing and is bent and extends within the bathtub. A duckboard is provided on the support rod in the bathtub. A control device in the housing is coupled to the shafts and extends from the housing for selectively raising and lowering the shafts to selectively raise and lower the duckboard via the support rod.
