My sister-in-law had ALS. She missed having a tub bath, so we found an inflatable tub that could be put on her hospital bed(at home)We had to use a Hoyer lift to get her in and out of it. However, the water cooled so quickly and she would get cold. so I had a "thingy"lol that went around her and covered both her and the tub. It kept her from getting chilled and helped to keep the water from cooling as fast.
