Perfect for 2 people!
PostedApril 13, 2016
Though 3 persons can fit this spa just fine, it is luxurious for two! All three seats are quite different but all all comfortable. I love moving from seat to seat to experience all the massage jets! Relaxation at its finest!
By Customer Service Caldera Vanessa, April 26, 2016
Absolutely agree! The Kauai spa is a fabulous compact spa. Jet placement and configuration is important to your spa experience. I am happy to hear that you are enjoying your spa.
Thank you for your review.

Still think it was the best decision we've ever made.
PostedApril 5, 2016
Great decision. My husband has had back surgery and he and I often do more than we should and after a sit in the hot tub we find the relief we are looking for. There are two seats and a lounge seat all of which have jets that will massage different areas of the body including wrist jets in one of the seats armrest which really relieve carpul tunnel, which I suffer with. It's amazing!! The Kauai model was small enough we could put it inside the house in the basement. We are older and didn't think we would use it as much if we put it outside. For us that was a good idea. It is very economical to operate. I would suggest this model for anyone who was looking for a beautiful hot tub with all the features but a smaller model, Absolutely love it!! We have had ours Kauai now for a couple of years and have absolutely no problems. If you are looking for a fantastic hot tub in a smaller package this is the hot tub for you.
By Customer Service Caldera Vanessa, April 19, 2016
Thank you for your review and recommendation. Jet location and seating configuration makes your spa experience that much more enjoyable.
Setting up your Kauai spa indoors sounds like a perfect option. Not having to consider the weather makes it easy to soak at your leisure. Enjoy!

Worse spa ever
PostedMarch 31, 2016
Bought this spa 2 years ago, after owning a Baja spa for over 10 years (trouble-free). Have spent more time "maintaining & fixing" this spa than actually USING the spa. This spa was installed, but the water would not regulate...no bromine distribution. Water discolored. "Battled" with the retailer for months, continually throwing chemicals into the spa to no avail. Finally, after begging and pleading, they sent a repair person out, who could not figure out why the spa was so discolored. THEN, Caldera informs retailer, that this spa needs a "distributer" put in the pump area (who knew? & why wasn't installed originally??). So, in essence, bought the spa & couldn't even use if the first 4 months of ownership! Tried to get retailer or Caldera to take the spa back, but no go. This resolves issues for a while, but then the circulator pump goes out. Fixed, refill spa (which each time requires removing panel door & "burping" the pump afterwards-major hassle as it requires undoing 8 screws). Following this, major "gunk" around spa. Get someone out again, now have to change filter, drain and refill. If you want a tub that is labor-intensive, this is the spa for you. I personally plan to sell it and if you are considering buying a Caldera, DON'T.

Awesome hot tub!!!
PostedJuly 30, 2015
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.

New spa
PostedJuly 27, 2015
The Kauai spa fit beautifully into the spot in my backyard replacing my old spa which had gone "end of life.' we like the look, it cycles on once a day which is very efficient and the cover and spa colors are attractive.
It is however a little small which can feel uncomfortable for 2 or more people, I knew that when I selected it but I didn't think the "shallow" effect of the shorter spa would be noticeable.
My daughter and her fiancé visited , used the spa a couple of times also and they loved it. The jets are strong and very relaxing when you can stretch out in it.
I am just know checking the water again and have yet to flush/change the water so far I am very pleased with my Kauai spa overall.

We Love It
PostedJuly 9, 2015
We purchased the Kauai spa after shopping around for several months. We were looking to replace our broken Thermospa that we purchased back in 1999. We loved the design and seat placement in the Kauai and we enjoy it on a regular basis. I had two bad knees at the time of purchase and would go in to relieve my aches and pains. Now I have two knee replacements and it is great for doing all my bending excercises in. It also is great for lower back pain the jets hit in all the right places. My husband and I enjoy the spa almost on a daily basis.

Laurel's Kauai
PostedJuly 6, 2015
We have found the Kauai to be a spa with excellent jets, fairly easy to maintain. Adjusting chemicals and cleaning it regularly Is work on any spa, and this is probably about as easy as it can be. We use it in the classic way, which is to relax and help ease muscle strain. Again this is probably as good as it gets. We just wish we had more free time to enjoy Laurel's Kauai.
Response from Caldera SpasBy Jaclyn, Customer Service, July 7, 2015
Thanks for taking the time to review your Caldera Kauai model spa, Lori! I'm so pleased to read of the benefits it's brought, and love that "Laurel's Kauai" has been hassle free. I hope you are able to etch out as much time as possible enjoying your tub.

Kauai Problem
PostedJuly 6, 2015
After draining spa, when filling back up, have to release pressure on the main pump to get jets to work. That requires taking the front panel off every time. That is a very disappointing part of owning this spa. I have reached out to the dealer, but can't get them to fix.
Response from Caldera SpasBy Ben, Customer Service, July 21, 2015
Hi Jimmy, thank you for your feedback on your Kauai model spa! Yes, at times, when refilling the spa, airlocks can get trapped in the plumbing, which can cause the jet pumps to chug. Are you filling the spa by placing your garden hose down the filter standpipe? Loosening the jet pump union allows any trapped air to escape.
If you do have questions or concerns, I encourage you to contact our customer service team at Watkins by dialing 800.999.4688 ext 8432, to speak with one of our knowledgeable reps. We are happy to help!

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!

Paradise Found!
PostedMay 15, 2015
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.
Response from Caldera SpasBy Marianne, Customer Service, May 18, 2015
Hello, WOW! That setting for your Kauai looks so beautiful!! Thank you for letting us know how much you love your new found paradise!! So happy to hear the dealer did a great job and got you into the perfect spa! Enjoy!

Reasonably happy with our kauai, just wish the frog would work
PostedApril 17, 2015
We got our kauai a couple of years ago now and water chemistry has been a challenge to say the least. The inline spa frog is less than worthless, it does absolutely nothing, which blows my mind because bromine will dissolve easily when you get it wet. I tried several things including creating a reserve, it wasn't until I took it out of the inline system and just dropped the cartridge into the filter basket that I got any results. And Watsons was less than helpful, I even tried to call spa frog directly, no help there either. If it wasn't for the difficulty with the chemicals I would love this tub, but as it stands it's almost more trouble than it's worth.
