My sister in-law is having an h2x put in, anybody familiar with it. Curiosity has gotten the best of me. For what they want to do it should fit there needs. http://www.h2xswimspa.com/
Should of posted this in pool and spa build!
If I didn't already have a pool and a spa, I'd want one.
My reservation is, what about the temperatures? A good temp for a spa is way too hot for swimming (IMO). I wonder if there's some provision for keeping the swim portion cooler than the lounging part. . .
