American Whirlpool has been creating industry-leading spas and swim spas for more than 40 years. During this time, their development teams have pioneered a number of innovations that lead the industry in build quality, performance and comfort.

This page illustrates why American Whirlpool is a proud brand of Custom Spas Direct. Their commitment to quality and innovation keep them at the top of the industry, with untold thousands of happy and relaxing customers nationwide.


American Whirlpool spas and swim spas are built to exacting standards of the home appliance industry, with metal frame construction and much more.

The steel structure means your spa can be serviced and brought to factory-new standards right on site at your home. Appliance Grade means your spa is built to the same service and safety standards as other major home appliances.

Count on your American Whirlpool spa or swim spa to provide you years of service excellence.

The frame is crucial to the integrity and resilience of any spa. That’s why American Whirlpool uses steel frames on the majority of its spas and all swim spas – and why it carries a lifetime warranty.

Should any issue arise during the operation of your spa related to the frame, American Whirlpool will cover repair or replacement and fix the spa back to factory specifications.

Also key to the longevity and integrity of every American Whirlpool spa and swim spa is the ABS sealed base.

As a key element in the spa’s support structure, the ABS base’s one-piece construction is a rugged foundation sealing the bottom of the spa, locking in heat and sealing out moisture.

The structure, insulation, and overall design of American Whirlpool spas and swim spas allow them to be serviced at your home, saving you time and money.

Technicians will restore your spa to factory specifications, increasing the lifespan of the spa.

American Whirlpool’s Northern Exposure patented thermal barrier technology recycles heat energy for more efficient heating and lower energy costs.

When American Whirlpool builds your spa, they line all four sides plus the floor and cover with reflective copper material. This reflects radiant heat energy generated by the spa pumps back into the spa and plumbing, raising and maintaining water temperature.

In addition, the entire spa exterior (just inside the DuraMAAX cabinetry) is wrapped in industry-leading 3M Thinsulate™ insulation, the same incredible material you’ll find in quality winter wear like jackets and gloves. This three-layer design ensures energy created by the spa stays in the spa.


American Whirlpool’s Northern Exposure insulation system features eco-friendly BlueMAAX® insulation.

Made from recycled natural fiber, BlueMAAX 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 fire retardant.

BlueMAAX replaces the urethane foam in “foam-filled” hot tubs. (Foam filling produces volatile organic compounds (VOCs) which are harmful.)

BlueMAAX – better for you, better for our environment.

Whether it’s diminishing the stresses of everyday life, healing a sports injury, massaging sore muscles, relieving stiff and aching joints from arthritis, or simply helping you achieve a good night’s sleep – your American Whirlpool spa can help with Physician designed Zone Therapy®.

Zone Therapy utilizes strategically positioned jets to target specific pain zones that contain muscular trigger points. More jets don’t necessarily mean a more effective massage. 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.

The Zone Therapy concept was designed by medical specialists in the fields of physical rehabilitation and massage therapy exclusively for American Whirlpool.


A neck massage therapy system is one of the most relaxing features in a hot tub. The reverse molded Comfort Collar’s unique cushion supports your neck, gently cradling your head while adjustable cyclone jets massage neck and shoulder muscles.

The Comfort Collar also allows a relaxing massage above the water line, it’s like having your neck massaged by a loved one.

This hallmark feature is one of the reasons many have already chosen an American Whirlpool spa.

The same insulation that makes an American Whirlpool spa energy efficient also aids in its ultra quiet operation.

Sound energy is trapped and deadened inside the hot tub by the insulation sound barrier.

Quiet operation is essential to ensure a peaceful relaxing experience throughout the entire backyard.

Insulating and covering your hot tub is extremely important. American Whirlpool’s premium-grade insulating covers contain a unique copper lining, removable heat-sealing pillows to vent excess heat during warmer weather, and a tailored fit to keep in heat during colder weather.

The WeatherShield™ cover material withstands harsh weather while remaining light in weight. Strong stitches result in less tear-outs, and they offer superior sun and fade resistance.

The insulation system in every American Whirlpool spa and swim spa is warrantied to maintain the same insulation value it had at the time it was manufactured, for the life of your ownership.

The high R value, Appliance Grade™ construction will allow a technician to service the entire hot tub and bring it back to factory specifications at home.
