Best Home Investment Yet
Outsanding quality, very easy to maintain crystal clear water. Have had now for 6 months use it almost every day. Pumps are quiet and very powerful. Up keep is low due to the chemicals needed.

vacation at home
Love having a retreat right outside my back door. This is a great spa... easy to take care of water and you do not notice it on your energy bills. Last year we had a polar vortex and never had a problem with the spa.

Great tub No service after Sale
I bought my Hot tub in July of 2013. It works great but I had some cosmetic issues with the side panel coming off. I contacted the San Antonio company I bought it from and they said they would check with the manufacturing company. It is now 9 months later and they still have not fixed the tub. I am very disappointed in Sweet water Hot tubs in San Antonio ,Texas. I do not recommend anybody use this company . Sincerely Dr. Nelson

This is the One to Get!
This is a great a spa. After owning it for three months I could not think of getting anything smaller in size or features. The one thing to note is that if you're tall the lounger might not be a perfect fit. I'm 6'5" and the lounger is not quite where I'd like it to be.
The jets in the spa are great. I have a had two previous back surgeries and purchased the spa to help with discomfort and lower back pain. This spa has been a huge help reducing pain levels and relaxing sore muscles.
The spa is easy to operate and maintain. has great features, and if you like a lot of jets I don't know that I've seen a better spa out there... and I've looked a lot.

Wonderful Experience
I have owned my Caldera Cantabria for 4 years now and have not experienced one problem. The tub is very comfortable and large enough for you and your friends to stretch out. I live in Reno which is very cold during the winter and I keep my spa at 101 degrees year around with very little difference on my electric bill. I use my tub daily and would highly recommend a Caldera Spa to anyone who is in the market for a Spa.

Definitely a wonderful Spa!
We have owned our Cantabria for almost a year now and have enjoyed it since day one. Even with the hot southern summer we just set the down to 95 and it still is such a joy to soak and relax in it. The FROG system makes maintenance a joy. We originally tried the Silver Ion Cartridge but that seemed more of a hassle than help to me. Maybe I was doing something wrong, but ever since switching to using the FROG it has been a joy. The Cantabria is definitely the Cadillac of Spa's and I am very glad we chose to go that route. The sound system is wonderful and the relaxation is even better!

Excellent with minor quality issues
Our Cantabria spa is probably the best investment we've ever made to our backyard - we use it daily and it works wonders. Unfortunately there is a quality issue with our EuroJets - after each session there are 1-6 laying in the bottom of the tub. The local dealer is going to have to glue them on with silicone the next time we drain it. Other than that it has been an awesome experience.
