Abstract: A displaceable seat is carried by support bars with outer support legs. The inner ends of the bars rest through rollers on rails extending across a bathtub. The outer support legs extend downwards to terminate in casters which rest on the bathroom floor and preferably have a brake member. A person may be readily moved from outside the tub into the interior for showering by advancement of the support bars and seat along the rails, and shifting the outer support legs towards the outside wall of the bathtub in an “accordion-like” manner.
