Nordic hot tub
add on features & Accessories

Stainless Steel Bands

Our Stainless Steel Banding is a tribute to the original hot tub with a modern twist. “Easy to adjust” locking mechanism gives quick access to components. The use of high quality, 201 stainless steel provides everlasting beauty and gives your hot tub a retro and natural look.

Nordic Wrap™ Insulation

We insulate all Nordic Hot Tubs with a rigid, closed cell, 2-pound density foam which is sprayed onto the exterior of the hot tub shell. This helps hold your hot tub temperature beautifully throughout the year in most climates. But, if you live in a colder climate, Nordic Wrap™ provides an additional layer of insulation to help protect your hot tub from the rigors of more extreme low temps. This adds an additional 9.5 R-Value to the already substantial 7 R-Value-per-inch of our sprayed foam insulation. By adding this layer of protection, Nordic Hot Tubs meet or exceed the stricter Title 20 Appliance Efficiency Regulations as mandated by California’s Energy Commission.

Freshwater iq system

FreshWater IQ is an in-line self-monitoring salt system that tells you what it needs to maintain clean, natural-feeling water, with less time and effort. Because we believe your hot tub should take care of you, not the other way around. Made for Caldera® Spas, FreshWater IQ comes standard on all 2024 and newer Utopia® Series spas and is an available option on 2024 and newer Paradise® Series spas.

Cool zone Hot Tub Cooling System

“It's over 100°F outside, and we are staying cool in our Caldera® spa.” With the CoolZone™ hot tub cooling system, your 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. 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.*


The FreshWater Salt System sanitizes water by using a maintenance-free*, disposable cartridge to generate chlorine from salt. The cartridge lasts four months and can be easily replaced in seconds without tools or dealer assistance. Simply set the desired chlorine level with the touch of a button, and the system will automatically generate the appropriate amount of sanitizer, eliminating the guesswork of manual dosing.
