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!!!

Great hot tub
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
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
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.

Kauai spa
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.

Why didn't we do this before?
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.

Excellent after fixed
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.
