Master Spas

Master Crafted Spas

Master Spas has worked for nearly 30 years to perfect your spa experience. Each design is master crafted to achieve enhanced, innovative therapy and high tech advancements in construction, performance, insulation, filtration, and heating systems.

The four Master Spas series were designed with the following features:


Master Spas meet the stringent energy standard of the California Energy Commission (CEC). The Polar Wrap Insulation System with Icynene has dramatically raised the bar on standard urethane foam insulation systems used by almost all U.S. spa manufacturers.

What is Icynene?

Icynene is polyicynene expanding foam insulation, an environmentally safe development in low density, cellular plastics. Chemically, it is in a class of its own. It allows foam to be sprayed without ozone destroying gases or formaldehyde. The micro-cells of this breathing material are filled with air and there are no gas emission hazards. Icynene is the only insulation material certified by the Envirodesic Certification Program for healthier air quality. The Icynene Insulation System expands to 100 times its initial volume in seconds to insulate and air-seal the spa envelope. The resulting blanket of soft foam insulation forms a continuous thermal barrier that eliminates cold spots and significantly reduces energy costs. A consistent, comfortable temperature is maintained inside the spa while cold air is kept outside. By minimizing air leakage, there is a reduction of airborne moisture movement through the spa envelope. This helps to prevent condensation, which can result from moisture-laden interior air contacting the cold outer layers of the wall. Icynene offers peace-of-mind to homeowners by minimizing the potential for condensation related problems, such as the growth of mold and mildew under the spa.


Master Spas invented and installs their patented Eco Pur® Water Filtration System on every hot tub. Doing so allows us to assure you that the quality of the water is beyond all industry standards. It’s done by using the same multi-stage filtration techniques as Mother Nature. The advantages of Eco Pur® filtration are many, and you can count on this process to help keep your water clean and clear.
And talk about efficiency. Every drop of water is
circulated through the system 10 times per hour while using much less power than a standard system. That means your Master Spas tub conserves both water and energy without skipping a beat of providing pure hydrothermal therapy and relaxation enjoyment.

Macro Pre Filter

The Macro Filtration stage uses a macro of coarse filters, similar to a natural gravel filter, to remove all large contaminants and debris that enter the filter area. This allows for higher flow rates through the filters and increases the life of the cartridge. The Eco Pur Polishing Filters 
add an additional stage of filtration to help polish the water to a sparkle.


Master Spas ozone system uses a high output Corona Discharge Ozone generator to help ensure that any remaining bacteria or metals will be destroyed.


Relax in the clean, clear water of a Master Spa. Master Spas offers built-in Microban antimicrobial product protection to inhibit the growth of bacteria that cause odors and stains on the surface of the spa shell.


Now, even outdoors, your Master Spa tub will keep its showroom looks for years. The exclusive DuraMaster™ Polymer Skirting is made of high-impact weatherable polymer. Unlike wood skirting which requires labor-intensive maintenance, your DuraMaster™ cleans up easily with a cloth and garden hose – with virtually no fading or color change.


Every Master Spa is portable and totally self-contained, with no special plumbing or drainage needed. All that’s required is a flat, level surface, such as a patio or deck, which can support up to 4,000 lbs. It is up to you where to place your spa, taking into consideration privacy and access. A licensed electrician can connect the wiring to a 50 amp 220V GFCI breaker. Then fill your spa using a simple garden hose, add the chemicals, and you are ready to enjoy the pleasure of your spa within hours.


Bio-Magnetic Therapy

The exclusive, patented Master Force Bio-Magnetic Therapy System is available on most models. Used for centuries to help relieve pain, improve circulation, reduce swelling and alleviate stiffness, magnetic therapy is seeing its rebirth in modern medicine. Today, more and more doctors and physical therapists are using magnetic therapy for the treatment of back problems, arthritis, and sports injuries. Nearly 70% of all professional athletes regularly use magnetic therapy for pain relief and performance enhancement.

How does it work?

The Master Force Bio-Magnetic Therapy System applies magnetic therapy to pressure points on the neck and back with the strategic placement of powerful magnets behind the Aqua Pressure seat and in the neck area on the reverse molded seat. Neodymium rare earth magnets are used to create a powerful magnetic therapy field.


No other spa gives you as many therapeutic jet configurations with up to 115 jets on some models. From the full-body massage, to concentrated neck and shoulder relief, to lounge and cool-down seats, you get the spa experience that is just right for you. Plus, most of the Master Spa jets are adjustable from a full 100% power down to as little as 10%, so you can customize every seat in the spa.

Extreme Therapy Seating and Jets

Master Spas has taken therapy to the extreme. Part of what makes every Master Spas tub a favorite among critics and customers is the finely-crafted, form-fitting seats. Every seat is ergonomically designed to fit the contours of your body. Using advanced computer-assisted design, Master Spas engineers have created form-fitting seats that perfectly accommodate the human body. Therapy has been taken to the extreme simply by creating seats that wrap you in comfort and that deliver the ultimate in hydrothermal therapy from head to toe.
