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.

Rated 5 out of 5 by enjoying it
We had been looking for a new spa for over a year, ours was fading (15 years old). We had seen many even put a deposit on one, then canceled as the deal was not just right. We met with Keith at Tradewind spas and were comfortable with his salesmanship (no high pressure) presented the facts, had us wet test the spa and made us a fair deal. The spa itself it quite enjoyable, the footwell jets are the best part, the sound system is also very nice as I used to use a portable radio. All in all this is a very good well made tub with nice well designed features.

Perfect addition to the spa-ish look we set out to accomplish
Added benefit, we see the kids more than ever
It is a thing of beauty requiring minimal attention

Spending time in this hot tub will take you away from the day to day. Having a rough day at work - jump on in before bed and let that tension go! Having friends over - there is plenty of room and you don't "touch" toes and feel awkward with the neighbors in the tub!

Rated 5 out of 5 by Best purchase ever!
We couldn't decide if we wanted a pool or a hot tub!! We chose a hot tub and we are happy with our decision. We now have grandchildren and don't worry about them falling in the water!!
We love to relax in it almost every night. In the summer, we just keep the water warm and enjoy it just as much!!
I also enjoyed it after receiving chemo treatments!! It really helped with the achy side effects from chemo!!

Rated 5 out of 5 by 1st Time Hot Tub Owners
We bought our Caldera Cantabria (2010 model) in September 2011 after having bought a new home. As we approach the 4 year anniversary of our purchase, and as first time hot tub owners, I would have to say we have been VERY pleased with this significant purchase. Our Cantabria has proven to be reliable over the course wildly varied weather conditions (scorching hot summers and cold/snowing winters). When we did have a problem with the circulation pump, it was replaced quick (and without cost) as part of the comprehensive warranty. At the end of the day (literally), we love finishing our long days with a glass (or two) of wine, while the hot tub pampers us and takes us away from our sometimes hectic daily lives. The best feedback I can give is this...I have NEVER regretted making the purchase!

My wife and I love our Cantabria hot tub!
It is so relaxing and inviting after a stressful day, and we emerge from our soak feeling refreshed and renewed.
We bought a floor model that had the sound system installed - and we are so glad we did. Before our purchase we were thinking the built-in bluetooth speakers would be a not so important add-on, but we use them every time to listen to our favorite local station playing blues and soul music! Add a couple of glasses of wine and we are at the Spa!! Nothing better!
