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 !

Well worth the money!!
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!!!

Love my hot tub!
This tub is a perfect size for my deck and me. Very easy to maintain and clean. The jets for the back are awesome. Feel like I just had a massage.

Just Perfect!
Few days go by unless it's below zero that I'm not lounging in my Caldera Spa! I bought it last year at the Alaska State Fair after visiting every Hot Tub booth. It has been exactly what I'd hoped for! I LOVE my hot tub!......Beth

Best investment ever
I wish I could sleep in it as it is so relaxing I just hate to get out. Helps relieve painful issues of fibromyalgia , arthritis, and bad back. It is so easy to maintain with the in-line frog system. A great investment. II use it year-round!

excellent purchase
We love the Kauai hot tub, perfect size for our smaller patio. The jets are more powerful that we thought they would be based on the overall size. We have had the spa for 2 months and love it.

Paradise Found!
After an extensive search of local spa dealers and online, my daughter and I chose the Kauai for our small Huntington Beach backyard which I remodeled into a family retreat. Looks, comfort and hydrotherapy were important features in a spa, and we were willing to pay a little bit more to get the best for our project. Our Kauai spa has been in use for over a year, and we are still very happy with our purchase. Ryan, our dealer, was great with installation and startup.

Just what I needed
I am a firm believer that my daily hydrotherapy in my hot tub is what contributes to my mobility. 5 years after back surgery, I am able to do just about anything! My new Caldera hot tub is energy efficient even in an Alaskan winter. Super easy to maintain, I love it!
