Coolzone Cooling System

Be Cool In Your Hot Spring or Caldera Hot Tub
With the CoolZone™ hot tub cooling system, your Hot Spring or Caldera spa can both heat and cool the water – something that is not possible in most hot tubs. This easy to use innovation expands your hot tub use, so you and your family can enjoy hot tubbing more, all year long.
Get PricingWarm or Cool — It’s Your Choice
A home hot tub provides a great deal of relief and enjoyment in winter. When the cold sets in deep you can raise the spa temperature, lift the cover, and sink into warmth. In summer, or if you live in an area with a year-round hot climate, the joy of a hot tub can seem more elusive. But with CoolZone™, available only from Watkins Wellness®, you can tweak your hot tub temperature setting to refreshing cool temperatures in warm weather. Whether you want to enjoy cool water to refresh, for its benefits after a hard workout, or as a way to spend quality time with your family in summer, CoolZone can help you find the best hot tub temperature setting.


Flexible and Energy-efficient
Similar to the way an air conditioner cools your home, the CoolZone™ system cools spa water to as low as 60 degrees. And when you’re ready to warm things up, the system works with your spa’s heater to efficiently raise the temperature in just a few hours. Depending on factors like ambient air temperature, the CoolZone™ system even has the potential to lower operational costs by reducing the time required to run the standard energyPro® heater that keeps the water hot.
Perfect for Athletes and Health-Conscious Spa Owners
A hot tub with CoolZone can provide benefits that athletes of any stripe will appreciate. Whether you’re maintaining a daily fitness routine or training for a competitive event, soaking in cool water can complement your healthy lifestyle. For example, researchers have found that cold water immersion after an intense workout can accelerate muscle recovery and improve performance. In fact, some basketball players use cold water immersion to improve jump performance. A cold soak at 60° F in a jetted spa could be just what you need to score points with your coach or trainer!
