Rated 5 out of 5 by Perfect Size for our Lanai
Having had a larger spa taking up a lot of space, this Kauai is perfect for us!
Low profile and it does not dominate our space - love the attractive color, and so easy to take care of inside and out!
great tips from our Caldera Dealer for set up and maintenance, and the Spa Frog system is great !

I love the set up of the Kauai. The lounger with the jets on my legs is the best thing after a day of working/ standing on my feet. The side seats have the most wonderful jets for lower back and shoulders. I really get a great massage sitting in either seat. So glad that I searched until I found what I wnated in a hot tub!!!

The Kauai is a smaller version of Caldera, but don't let size fool you. It has so many jets that you will not realize you are in a smaller version. It is very easy to maintain and we could not have been happier with our choice. We put ours in the basement so that is why we went with the smaller Kauai. Have not regretted our decision.

We are so happy we purchased the Kauai spa. We use it often in the fall and winter, only weekends in the summer (it's hot outside). So relaxing and comfortable.

KAUAI spa is fantastic. Comfortable for three people, but can fit four if small. Relaxing enjoyable. The lights at night brighten up making you feel like your in a professional private spa. Low cost electric bill. We love it thsnks .Vincent

This hot tub has been a great purchase. Not only for recreational use but also for healing purposes. I have found that it has tremendously helped with my arthritis. I would highly recommend this hot tub.
