What are the reasons to own a walk-in tub for seniors with post-surgery recovery needs?

Low-entry access and a seat may be useful after recovery, but bathing after surgery must follow the surgeon's instructions. Immersion may need to wait until wounds have healed, and transfers may be restricted. Have the intended tub and seat assessed against those needs. Walk-in tubs should be compared as bathing equipment, not advertised as speeding healing or replacing rehabilitation.
