So no matter if you want to strength-train, tone, or even add muscle mass, the is setup can allow you to maximize your efforts with efficient heat dissipation and the comfortable environment of warm water.

Your AMERICAN WHIRLPOOL® hot tub features the worlds first Medically designed jetting systems for the ultimate massage. Whether it’s diminishing the stresses of everyday life, relieving stiff muscles or simply helping you get a good night’s sleep – medically designed Zone Therapy® utilizes correctly positioned jets to target pain zone trigger points. Precisely locating the correct size jet and massaging action where they are most effective is key to relieving pain and stiffness throughout the entire body.

Performance Seating® means AMERICAN WHIRLPOOL® has the most comfortable spas in the industry. Each seat is designed to provide full body immersion and proper posture, in harmony with their respective jetting pattern, for comfort, superior jet performance and reducing stress on your lower back.

For over 40 years we have designed the worlds most comfortable hot tubs thanks to patented features like the zero gravity Performance Seat®. Seats are specifically molded to fi t a variety of shapes and sizes so you can find the one that’s right for you. Deep immersion seating provides ultimate comfort, while armrests and Foot Relief Zones® seem to mold to your body.

A neck massage therapy system is one of the most relaxing features in a spa. The molded Comfort Collar’s unique cushion supports your neck, while the jets massage neck and shoulder muscles. The Comfort Collar® is like having your neck massaged by a loved one. This hallmark feature is one of the reasons many have already chosen an AMERICAN WHIRLPOOL® hot tub.

Lighting systems display multiple colored lights in pre-programmed random, solid or alternating colors. Built-in internal and optional pedestal lighting illuminates the spa for both safety and romance. A selection of unique color options can further enhance an already perfect evening, taking backyard fun to soaring new heights.

APPLIANCE GRADE AMERICAN WHIRLPOOL® hot tubs are the worlds first steel frameAppliance Grade® hot tubs. The steel frame provides greater structural integrity than wood, as well as superior corrosion protection for a much longer life. Unlike wood It will never rot, warp, or crack. Stronger, more durable, and ideal for the environment – it’s the reason AMERICAN WHIRLPOOL® is the ultimate hot tub. The steel frame and Northern Exposure® Insulation allow for complete service of the entire structure and all mechanical parts. Essentially the spa can be serviced to factory specifications right in your backyard, for the lifetime you own it. The hot tub is built to the same service and safety standards as other home appliances. STEEL SUB-STRUCTURE The steel frame is the backbone and support for the entire spa. The steel structure of your AMERICAN WHIRLPOOL® hot tub carries a lifetime warranty. ABS SEALED BASE The ABS Sealed Base is an integral part of the support structure in an AMERICAN WHIRLPOOL® hot tub. Its one-piece construction provides a rugged foundation that seals the bottom of the spa, locking in heat and sealing out moisture. Why is this better? Conventional foam-filled hot tubs are extremely hard to service and are often damaged in the process. It is very costly to bring these back to factory specifi cations.
NORTHERN EXPOSURE Northern Exposure® is the ultimate hot tub insulation system. This patent pending thermal barrier technology recycles the free heat energy for more effi cient heating and lower energy costs. All four sides of the spa, plus the floor and cover are lined with reflective copper material to reflect radiant heat energy generated from the pumps back into the spa. Heat is absorbed back into the plumbing helping raise and maintain water temperature. Finally the entire exterior of the hot tub is wrapped in 3M Thinsulate® Insulation, the same incredible material utilized in winter clothing. This three layer patent pending system ensures energy created by the spa stays in the spa. BLUEMAAX™ The Northern Exposure® Insulation System features our eco-friendly BlueMAAX® insulation. Made from recycled natural fiber, it is approved by the U.S. Green Building Council. The insulation contains no chemical irritants, is treated with a borate based solution to prevent mold/mildew growth, pest infestation, and acts as a fi re retardant. BlueMAAX® replaces the urethane foam in “foam filled” hot tubs. (Foam filling produces volatile organic compounds (VOC’s) which are harmful to the environment.) INSULATING COVER LIFETIME INSULATION WARRANTY The insulation system in your new AMERICAN WHIRLPOOL® hot tub is warranted to maintain the same insulation value as it had at the time it was manufactured. The high R value, Appliance Grade® construction will allow a technician to service the entire spa and bring it back to factory specifi cations at home.

DuraMAAX® is a state of the art wood-alternative material that has the look and feel of natural wood, without the maintenance. The material is impact resistant, impervious to weather or insect damage and will never splinter, crack or rot. The attractive exterior locks in heat and seals out cold air providing a beautiful look and feel

The exclusive TheraMAAX® Jets utilize a scientifically designed grill surrounding the nozzle of the jet to reduces drag and cohesion of the jet stream. The three spoke stainless steel escutcheon makes it easy to adjust the power of the jet.

AMERICAN WHIRLPOOL® hot tubs utilize Direct Drive 56 frame pumps in all of their 240 volt models. These are larger, and more powerful motors that eliminates mechanical switches allowing the pumps to run cooler for a longer and more energy efficient life.
