Abstract: A shower-commode chair and bathtub transfer track can be connected together to transfer a person on a sliding chair seat between the chair and the tub area of a bathtub in a seated position without being lifted from the seat. The chair has an adjustable height frame supported on wheels and a pair of horizontal channels secured in parallel spaced relation extending from side to side. A seat is supported on rollers in the horizontal channels. The bathtub transfer track has a pair of elongate channels secured in parallel spaced relation to extend transversly from one side of the bathtub to the other on the top surfaces of the bathtub walls and span the open area of the bathtub to receive and support the seat. Removable arm members on the chair frame retain the seat on the chair frame when attached and allow movement of the seat when removed. A removable backrest connected to the seat moves with the seat.
