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.

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.

First time owner LOVING it. Working through some kinks
ABSOLUTELY LOVE THIS HOT-TUB!!! I am working through some water issues. I will get there. Have a couple of issues with the heads to jest falling off repeatedly and one of my speakers won't come up. For a tub that costs this much I expect these things not to happen in first month. Don't get me wrong though I LOVE it. As long as I get these small issues resolved I would give this 5 stars all around.

None better!
We purchased the this model this Spring because of my husband's back injury and its therapeutic value. Having been in hotel hot tubs I was not real enthusiastic about it and felt that I would only give it a try to please my husband. I'm now a believer! Other hot tubs bubble hot water around you but the Caldera spa tub can actually do a very effective deep muscle massage. The lounger is extremely powerful and has several settings for a custom massage. We use it almost nightly for the last 5 months. We did enclose it in a gazebo, placed a spa bar inside, and bought tall candle pillars to light in the evening. It has a summer setting to save cost, and the chemical guidelines are located under the filter lid. I can not truly give the highest rating for energy efficiency, I do not know how much it costs to run as it is summer and we have our air conditioning on 24/7. I hate to say this but my husband was right. It is worth every dime.

Great Spa!
Despite some startup software bugs, we are extremely happy with this spa. The issues were fixed under warranty and efficiently by the dealer. Our purchasing experience was pleasant at Home Escapes in Reston, VA. Rosanne patiently answered all of our questions and has kept in touch to ensure we are satisfied. Dave the owner has been great too. We purchased our tub in time to have it installed before Christmas. We have the tub installed on our patio, so we enjoy the stars and snowfall when we are tubbing. We love that every seat in this tub fits the both of us. While we didn't need a big tub, the size of the Cantabria comes in very handy when we have visitors. Care of the tub is easy with simple cartridge and filter changes plus the typical weekly shock and water testing. Based on our current experience, we will highly consider replacing the tub with another Caldera Spa when the time comes.
