Rated 5 out of 5 by from Great Spa My wife and I were looking for a small energy efficient spa. We looked t several brands and models and finally settled on the Aventine. At only 150 gallons it fills very quickly and it is very easy to keep the water quality in check.

Rated 5 out of 5 by from I start and end my day in my Caldera Aventine hot tub. We were resistant to buying a hot tub, afraid that we would not use it enough to justify having one. But since I was recently diagnosed with RA, we decided to try one. Three weeks ago we purchased the Caldera Aventine for two people, which three people could comfortably enjoy. It is making my RA pain so much more tolerable, and it helps me loosen up my muscles and joints tremendously. I start, and end, each day in my hot tub. Jason, our sales person, was so considerate and knowledgeable and has kept in touch with us since our purchase. The delivery people did a phenomenal job, even filling it with hot water they provided so that we were enjoying our new hot tub within a few hours after installation. The entire Backyard Leisure team talked with us in depth while helping us decide on the right hot tub for our needs. Upkeep is so easy on the Aventine. We had it installed in our sunporch so that outside debris wouldn’t be an issue. We couldn’t be happier with our decision. Buying a hot tub has been one of the best investments we’ve made, and buying from Backyard Leisure topped it all off to make it such a pleasant experience! Thank you, Backyard Leisure Associates in Terre Haute, Indiana and thank you, Caldera!
