Great Hot Tub
PostedJuly 18, 2015
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.

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!

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.

Great hot tub
PostedMarch 16, 2015
It is very comfortable and with two you have plenty of room. The jets are all adjustable so it will hit you wherever you need it to. It has helped my RA flares and sore muscles after working out or playing sports. I treasure my Caldera Paradise Kauai...

Kauai hot tub
PostedOctober 1, 2014
We've had our hot tube for a year now. We have always enjoyed them at vacation spots, but never were sure we could afford or maintain a hot tub. However, after just going to places just to use on, it became apparent we needed our own. It was installed in a three sided glass room on our front and private deck. Since then it is used almost daily by one or both of us. After a hard day of ranch work, the aches and pains are surely reduced. We like the hot tub and serenity of the time spent in the hot jet focused water, that we are now adding a separate bedroom entry to a new 'only' hot tub room. It has become such a part of our life that when we travel we cannot wait to get home to our private retreat. This has been one of our best investments. I am sure there is a Caldera Spa to fit any persons needs.

Great investment for health and comfort
PostedSeptember 6, 2014
We have had our Kauai hot tub for three years now and have enjoyed it every time we get in to relax. There is nothing better to relax tired muscles and relieve my arthritis pains. This saves me from going to expensive spas. My wife and I use our spa time to converse and enjoy bonding time. This is much better than the motor home we sold to buy this spa.
Response from Caldera SpasBy Ben, Customer Service, September 11, 2014
Hi there happy Kauai owner! I couldn't agree more, the health benefits of a daily soak can provide so much relief, all while spending quality time with those close to you! Plus, its great to hear you found something that you can enjoy together!

Kauai spa
PostedSeptember 6, 2014
we love our kauai. Built for 3 but big enough for 4 comfortably. we love the changing colored lights plenty of glass rests. Can't get over the temperature controls: you can keep it cool in summer but with a push of a button temperature quickly rises. the only problems we've had is maintaining pH alkaline balance, and sometimes mildew builds up on the cover and needs to be cleaned with bleach. It is a dream on our new enclosed porch.
Response from Caldera SpasBy Ben, Customer Service, September 22, 2014
Hey there Kauai spa owner! Sounds like you found the perfect fit for your family's enjoyment! For help with your spa's water chemistry, check out the spa's owner's manual, contact your local dealership, or call us at Watkins Customer Service by dialing 800.669.1881 ext 8432. Keep that dream alive with continued use of your Kauai spa on your new porch, very exciting!

Spa Frog Worthless
PostedSeptember 5, 2014
We really like the small size of the Kauai spa, just perfect for the 2 of us. Everything works well except for the Spa Frog system. It apparently was not designed to go with this spa. Even with a setting of 1 on the bromine cartridge the bromine level goes way high. The only way I can use it all is to constantly reset the cartridge from 0 and then back to 1 then back to 0. If I leave it on 1 it just goes higher and higher. Caldera ignores my pleas for help.
Response from Caldera SpasBy Ben, Customer Service, September 15, 2014
Thank you for your honest feedback on the Kauai model spa, and the Spa Frog system! When given the opportunity, please contact our team in Customer Service by dialing 800.669.1881, ext 8432, to learn another tip to help reduce your Spa Frog bromine output. Glad you continue to enjoy the spa, look forward to hearing back from you!

Why didn't we do this before?
PostedSeptember 5, 2014
This is our first hot tub and we are wondering why it took us so long to get one! The smaller size is perfect for the two of us and it's located just outside our bedroom door, so we can slip in for a quick dip when it's cold outside. We will probably drain it next spring and not let water sit in it over the summer, but we are looking forward to some cool fall nights. It's easy to take care of and we couldn't be happier.
