The exercise spa is a non-energy efficient luxury. I have no excuses for adding this feature to our otherwise energy efficient design and execution. The Rio spa decision is a nod to my love for the pool we had in our backyard in Arizona. We enjoyed the water frequently and used it for the whole 11 years we lived there. So when I was dreaming that a regular hot tub might not be large enough, I started pricing swim spas but they were more than I felt comfortable spending on luxury. So here is what I bought and if you run into a similar model you might need these documents.
