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.
That's our plan as I mentioned earlier in the thread
I want to move the shower, put it where 'her' jacuzzi tub currently resides......that's an issue currently.
