Around here these things were the hot ticket about 5 years ago, we installed 4 or 5. Slow fill, slow drain, hot water capacity were all issues. Think some of the new ones may have a drain pump, which would just be another maintenance issue do deal with.
I'm mid sixties, wife and I are planning a bath remodel, trying to think ahead. Large walk-in shower, with room for a chair, overhead (rainforest) shower head with a wand on the wall. Keep it simple.
