I would not even consider a walk in tub. I don't think he could use it that long, and when I think about it wouldn't they have to sit while it fills up, and then again while it drains. My husband gets chilled quite easily so I don't think that would be good. Again I have a ceiling lift, so it doesn't matter what the height of the tub is. So far my husband stays in the sling while in the tub, as I haven't found a chair seat that would sit in the tub. Our tub is quite deep, so I am thinking that I may try the seat that we had in the beginning that lowered him into the tub. It had a head support, but not arm supports. The most important thing is that it doesn't allow him to slip out of it in the tub, which would mean something that would lean back. The tub buddy commode chair that he has would not allow him to be in the water. Drying him isn't too much of a problem, as I raise him in the sling over the tub, and dry his hair and face, and then drape than towel across his shoulders and chest. I use another towel to dry each leg and bottom and drape that over his abdomen and legs. I have a large towel on his pwc and lower him and the net sling into his chair. I remove the sling and dry his back while doing that. A towel warmer, or a heat lamp would be nice, as he chills much quicker in the evening. I put on his oversized T-shirt, do the rest of his evening care, put a new dry sling on and put him into his bed. I usually throw his quilt in the dryer, so it is still hot when I cover him up. A padded seat, that is in a reclined position for the tub would be ideal, but haven't seen one so far. The tub does have a reclining back, but he slides down, as his legs will not brace him.
