We love our spa! It's our very own private retreat. It had been became the hub for our most intimate conversations and favorite moments. Just the two of us can sit and relax together, soaking up every ounce of relaxation or invite friends to join for cocktails and hydration rejuvenation! The features, quality and ease of use allow us to enjoy with peace of mind and no stress!

Well i may be biased, I had worked 10 years ago for turbo tubs out of naperville il, The owner jay only sold top end tubs Caldera being one of them.
10 years later i bought a 10 year old Call Spa tub, had for 2 months, there were typical problems with the tub and got rid of it. I went out to a local dealer and purchased a a newer Caldera
Geneva tub "made in 2010" off showroom floor in 2012. to date so far no issues, the lighting power and looks made me very satisfyed with my purchase

My wife and I love our Caldera. The design is beautiful and the options make for a wonderful experience. The leg and back jets feel amazing.

I was apprehensive about owning a spa. I figure it would be a lot of work with little pay off. I was so wrong! Very easy to care for and we use it a lot more than I thought we would! I love it in the winter months and we also like the fact that we can easily control the temperature year round to fit our needs.
I have a lot of pain issues and the therapeutic effects has improved my health a great deal and we look forward to using it as often as we can.
