Sliding tub transfer bench lets the user sit on the 16.5 x 14 in HDPE seat outside the tub and glide along a 15-in sliding distance into the bathing area, which can reduce the need to step over high tub walls. The 9-level adjustable seat height from 19-in to 23-in helps the 41.5 x 19.5 x 33.5 in frame align with different bathtubs and user needs. A rustproof aluminum frame rated to 350 lbs and suction cup foot pads work with the locking seat to help keep the bench stable during transfers. A textured surface with drainage holes, a removable cutout opening, backrest, armrest, safety belt and shower head holders support more comfortable cleaning and bathing.
