I've been in non wheelchair rooms only twice and I would have to say that yes they are do-able. I cannot walk at all and was able to use the rooms. Both times I had to sit on a towel in the shower and have my wife turn the water on. I was able to sit in my chair and use the sink for brushing my teeth. Since your husband can stand for a short period of time, I don't see a problem at all. I would however suggest a manual chair the folds in half. 1) The bathroom door may be too narrow and 2) If one of you needs to get up in the middle of the night, a manual chair would be one less thing to trip over.
