Retirement/ Relaxation after exercising
PostedJune 27, 2025
I've have had my hot tub (Kauai) model for about 2 years now as a retirement gift to me. I have come appreciate this purchase on every level. I usually enjoy my hot tub after cycling anywhere from 25-30 miles of high intensity cardio. Other times I get in about an hour or two before going to bed for pure relaxation. As a person that lives alone who occasionally has company, the Kauai is all that I need!

Great fit for our small space
PostedMay 22, 2025
We have a small area and this worked great. And the sides are not overly tall which we like.

I use it daily. Good jet system, gets massage anywhere you need it. I downgraded it from 5 stars because the lights tend to be in your eyes. Many of them are located too high. Also, not crazy about dealer, very slow, very expensive service, but that's not a fault of the brand.

Well worth it!
PostedDecember 29, 2024
Best thing we could have purchased for our physical and mental health! Perfect for my husband and I and a friend or two. The jets are powerful, the lights are fun and it doesn't take up too much room in the backyard. It is saltwater versus chlorine, so upkeep does take time at first. Once you get the hang of the PH strips; it's a breeze.

Hot Tub Arrived Broken
PostedDecember 28, 2024
My tub arrived with the salt system wires not working, waited three weeks for a tech to come out to repair. Documentation on start up, salt system and IQ system was all over the place and very confusing. Never received an owners manual had to track down on your website how to work the control panel. Cover the company gave me is cheep and flimsy and one of the lock down straps pulled out 3 weeks into owning it.

Best little spa honor hurting joints.
PostedDecember 7, 2024
I use to have a Caldera hot tup but lost the use of it a few years ago when I moved. My old bones have been aching these day so I wanted a new spa. My area to place it was limited and I no lingered needed an 8 person spa so I chose the Kauai. I love the feel of the salt water compared to the chlorine based spa. I've had it for about a month now and use it everyday. The temperature being in the 10's and 20's don't bother me as the spa is only 5 feet from my house door.
It is a great stress and joint pain reliever especially after an all day ride on my motorcycle. I could not recommend a better from of relaxation.

What a difference a spa makes!
PostedJuly 17, 2024
I had contemplated purchasing a spa for several years. After a lot of research and shopping, I purchased a Caldera Kauai spa. After a week of using the spa, I could not believe the difference in how I felt! The jet arrangement and the areas that each station focuses on is spot on. The jets are adjustable and can be as gentle or as strong as you need them to be. The maintenance has been easy and manageable. One soak is all it took to know this spa was of high quality and worth every penny. I am really pleased with my Kauai spa. My only regret is that I did not purchase it sooner!

Poor quality with no customer service or follow-up
PostedMay 28, 2024
I purchased my Kauai product about 2 months ago from an authorized Caldera dealer (Hughes Pool & Spa's, Montgomery, AL) and have used it for about 6 weeks. This past Saturday I went to get in the hot tub (after several weeks of testing and getting my water balanced) and turned on the jets and nothing...nothing...even though the menu was showing the jets running no pump noises, no circulation of water...nothing. I reset the breakers and still nothing and literally dead in the water. I haven't had to drain or refill the tub because it's only been 6 weeks so this is poor quality, reliability and craftsmanship. Memorial day weekend so I call the dealer today only to be told it will be next week before someone can come and look at it. What was suppose to be an exciting (and expensive) purchase and experience has turned into a nightmare. Worst experience ever and worst purchase ever. If I could return and get a refund I would. Do not purchase a Caldera hot tub as they do not stand behind their product and do not provide customer service.
By Customer Service Caldera Vanessa, May 31, 2024
I'm truly sorry to hear that your experience with owning a hot tub hasn't been as exciting and relaxing as it should be.
It's important that working with your dealer is a positive experience, and I understand how frustrating it is to require service, especially during a holiday weekend. I appreciate you sharing your review, and I'm here to assist you.
Please look for an email from me. I'm looking forward to working with you soon.

PostedFebruary 29, 2024
Everything about our new spa, we love! Shopping for the right size spa for our needs was important and Affordable Spas in Redding was the perfect place to go. Great customer service! They were so thorough explaining everything and helping us choose the right one. They continue their great service with just a phone call! Choosing the salt water method has made it easy at keeping the spa clean. At our age we need easy! Very pleased and satisfied with our purchase!

It's just my wife and I, so this is the perfect tub for us. It's also just a 30 inch stepover...no stairs needed. We both love the lounge seat...great for the feet and calves.

Update on Previous Review
PostedDecember 17, 2023
I was the frustrated owner who recently complained about my KAUI shutting down all the time after only 3 months of use
Thank you to SPRING DANCE HOT TUBS in Jamison, PA, for sending a technician out, no charge. He discovered a valve that was faulty and replaced it. All good since. Love the benefits, health-wise, of this hot tub.
Thanks, also, to CALDERA SPAS themselves for having a rep reach out to me almost immediately to give advice!

Frustrating…shuts down a lot!
PostedNovember 8, 2023
This tub has done wonders for my arthritis but…I have to restart at the electric panel 10-15 times a week…or more.
Keeps saying to check for filter obstructions and there are never any. And, yes…the filter is clean.
I’m now going to pay a $99 service call for a 4 month old tub.
Not pleased…

Good spa. Disappointed in the service
PostedNovember 5, 2023
1st of all, it has strong jets. There are no jets for the hamstring area. The spa is probably a little overpriced.
The installers alerted me a cracked corner panel. They put in a service order for another one. After about 6 weeks, a service tech arrived. After spending over an hour taking off the old one, he said the new one was also cracked. After he left, there was insulation left on the ground. At this point, I don't know if another panel has been ordered. I have no idea of the status. Obviously, for 2 cracked panels to leave the factory is a serious quality control issue. I waited to see if I would hear anything concerning the panel before writing a review. I have heard nothing. I find this very disappointing. Unless things are rectified, I would hesitate to recommend your company.

Very Nice....
PostedOctober 8, 2023
It is a very solid unit... Love the salt system. Heats up quickly and the jets do a great job. Nicest spa we have ever had... and we have had a few. Also.... you get what you pay for.
