Beautiful hot tub. Well made and very simple to understand how to maintain as a first time owner. Well what are you waiting for? Find a dealer and go check out the many different spas available and treat yourself and family to nice relaxing evenings just soaking out on that patio. I sleep so much better after spending 15-20 minutes before I lay down.

Twenty minutes every day I get to unwind, get away and melt away the day's stress. I had wanted a spa for many years and finally got one. One of the best investments I have ever made. Highly recommend it, use it all year round. In the summer I drop the temperature and as the weather gets cooler, I start adjusting and find the right temp.

First let me say we did a lot of reseach before choosing the Caldera brand. We really are happy we chose this one. The care and maintenance is so easy. Seats 6 comfortably. We live in Fla and most people said its too hot to use a spa. Let me tell you how wrong they are!! Our thanks to everyone involved in making this high quality yet affordable spa!!

We have had our spa for 3+ years and love it! It is very easy to maintain, works wonderfully, and has easily met our expectations. The multiple jets with different intensity selections makes for a very relaxing experience. We would buy this spa again in a "flash!"

This is my second Caldera Spa I have owned; very easy to care for and very relaxing. The main reason I purchased the Caldera Spa the second time was because the experience I had with the first. I had a (5) year warranty which was about (6) months from expiring when I ran into some problems: I had the owner of Trade Winds Spa stop out to my house to inspect the hot tub and within (3) weeks they brought me out a new Hot Tub no charge to me. You have to love a company that stands behind their product!

Have owned this spa over 3 years. No problems so far. Very energy efficient in the Texas climate. I would definitely recommend this spa for future buyers.

My husband and I love our Caldera Marino Spa, and so does our three children. Ages 5,5, and 11. We use it 1-2x per week in the summer and 3-4x per week in the winter. It's been easy to keep up with, and I haven't noticed any changes to our electric bill. We never get into it and wished we hadn't. It's always a great idea!!!
