Our former elderly neighbor had to move from her house to an assisted living facility. She was a life-long soothing bathtub bather. She didn't like taking showers and having the water "beat" on her (her description), and like many older "permed" ladies didn't like her hair to get wet between appointments. Of course, assisted living units use only showers. For someone like her, a walk-in tub might have been a nice option.
The better hotels have ADA-compliant rooms but you have to request them. TCS and I stayed in one (we didn't request it; it just happened to be the last room available), and the bathroom was great! It had a large walk-in shower with multiple height-adjustable shower heads, handrails all around the shower, room, and toilet, and ADA height toilet, wheelchair access sink vanity, and very spacious. It had non-slip tile floor that continued into the area outside the bathroom. The door was extra wide. At the same time, everything was stylish. That's what universal design is about. Function and design combined.
