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!

perfect size
PostedJune 30, 2015
The Kauai is the perfect size for my wife and I. We have had bigger tubs and we found that we are just heating up water that is not being used. I use our tub almost every morning before go to work.

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
PostedJune 23, 2015
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!

PostedJune 23, 2015
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!
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.
Response from Caldera SpasBy Ben, Customer Service, April 20, 2015

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!

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.

High price low quality
PostedSeptember 5, 2014
Paid a lot more for caldera than other brands available hoping to get better quality but I've had two service calls in less than a year. Within the first first week they had to replace the pump because it would shut down after half an hour of use. Then the temperature started going crazy shooting up to 105 degrees with thermostat set to 95. The spa still makes a thunking noise and shuts down occasionally and won't run for hours and it's still less than a year old. I would not recommend this spa to others.

Excellent after fixed
PostedSeptember 5, 2014
We have enjoyed our spa except for the three months we were unable to use it. The reason for that is that Caldera provided the incorrect ozone generator for the spa to the dealer and when it died it left us with an absolutely useless spa until the dealer went through a three month cleaning process to remove all of the detritus that had clogged the entire piping system, the pumps, and the spa itself. Once they installed the correct ozone generator and cleaned the spa thoroughly we are back to total enjoyment.

Thank you for your review. I am sorry to hear that your initial experience with your hot tub was not ideal. However, I am glad that your dealer was able to rectify the situation.

I really like the jets
PostedSeptember 5, 2014
This hot tub really has perfect jets. Its comfy, easy to maintain, and just a very nice hot tub. We had to go with a smaller tub because of our zoning, but there are some drawbacks to a smaller hot tub. It's much less energy efficient than a larger tub- our electric bill went up about $50 in the summer and $100 in the winter. And while it seats 3, its really only comfortable for 2. If I had to do it again would go back and buy a house that they would let me put a big hot tub in, but If I couldn't I would buy this one again in a minute.

Since that time we never caught a cold. After a soccer game we ever relax in the spa so that we don't get sore muscles.
