The spa shell is the designed and shaped form that you sit in, and the most important component of any hot tub. Other parts can be replaced in a hot tub, but the shell cannot. Our ABS-backed acrylic spa shells are engineered for strength, durability, and are easy to maintain. Each seat has be ergonomically designed to fit the contours of your body. Many of our spas feature deeper foot wells for comfort and spaciousness. Built in safety features like steps and lighting are part of every spa we make. We add in luxurious touches, like comfort pillows, soft touch controls, adjustable jets and massage levels and drink holders. Our shell design and durability can't be beat.


USA Spa shells are manufactured with a patented, four-layer strengthening process called DuraBond™. This exclusive system combines the beauty of Lucite-Xtra™ acrylic with a layer of ABS for strength and integrity. A layer of double-strengthening material called IsoBond is then applied. IsoBond has all the strength of a fiberglass resin shell, with half the weight, and without the environmental concerns. The manufacturing process is completed with a thick layer of insulating polyurethane foam on many USA Spa models.


Lucite-Xtra™ cast acrylic is a non-porous material that resists stains such as those from build-up of lotions and body oils, which can ruin non-acrylic spas. Its durable surface resists chipping, cracking, and denting. Lucite-Xtra™ keeps its shine despite sanitizing chemicals, high temperatures, and exposure to sunlight. No polishing or waxing is necessary to maintain its appearance - just a sponge and mild soap.

USA Spas currently has 3 available cabinet colors on most models.

redwood redwood Gray
Redwood Standard Chestnut Standard Gray Standard

USA has always looked for ways to improve every aspect of the spas we build. All spas feature beautiful, maintenance-free cabinets. Our energy efficient cabinets are made from UV inhibited combined plastics with the beautiful look of fine wood furniture. Best of all, the cabinets maintain their beauty over time and in all weather. The cabinets provide a thermal-insulation barrier for the spa to help protect it and make it more energy efficient. Your spa will resist fading, rotting and insects.

Easily access your equipment and spa drain by removing the cabinet door panel. The panel should remain locked during use for safety reasons. Scratches don't show up easily on your cabinet since the color goes all the way through. The cabinet is sealed with a moisture proof bottom to keep air and water from coming in through the undersection of the spa.

WeatherGuard™ is the industry's best, maintenance-free spa cabinet. WeatherGuard™ is fade resistant with built-in UV-inhibitors. Unlike other poly-plastic cabinets in the market today that are thin and flimsy resulting in warping and fading, a USA Spa WeatherGuard™ cabinet is constructed of strong and durable polystyrene that won't crack, splinter or peel. This material is similar to high-end vinyl windows for your home. And since it replaces the wood of most spa cabinets, WeatherGuard™ is termite, moisture, and rot resistant and 214% more rigid than wood. WeatherGuard™ is energy efficient too - 62% more than traditional wood!


The USA Spa Dura-Frame Cabinet provides strong support and a thermal-insulation barrier from sub-freezing temperatures

    • Natural Wood Grain Appearance
    • Fade resistant with UV-Inhibitors
    • Insect Proof, Moisture Proof, and Lifetime Rot Resistant
    • Maintenance Free

LED-D: Add a factory installed LED light bulb with 20 points of light that creates the right evening ambience in your USA Spa. The LED-D light can also be retrofitted on existing USA Spas and replaces the standard 12V white bulb.

LED-M: A more advanced spa lighting package available on higher end USA Spa models is the LED Package M (LED-M) which includes 10 above-water perimeter lights and the LED-D spa light.

LED-A: The most deluxe lighting package available on select USA Spa models is LED Package A (LED-A) which not only includes 10 perimeter spa lights and a 4 inch main LED light, but also underwater lighting which illuminates selected spa jets, controls, valves and other spa features for a complete LED lighting experience.

Add the sound of music to your hot tub experience and take it to a whole new level! From the two speaker Wow Sound System to the deluxe, bass pumping Vibrasound System. You will find the right sound system to add to your USA Spas hot tub on SpaSaunaDirect.com. 

VibraSound Music System

Wow Sound

When you add VibraSound to your spa, you don’t just listen to the music – you feel the music! The built- in music system allows you to feel the music through the water as you enjoy your hydro massage. Four VibraSound speakers, a transformer and one subwoofer are build into the spa shell where the sound resonates – using the shell as a speaker.

The sound transmits through the shell and into the water for a complete surround sound experience. This revolutionary sound system for your spa represents state-of-the-art high fidelity audio. Enjoy sound that envelopes the entire spa instead of unevenly distributed sound from individual speakers. Sound is constant throughout the spa – allowing a deep bass and full sound even at a lower volume. 

Since the speakers are built in and not protruding from the top of the shell, the spa cover can fit securely with no bumps or cut-outs. There is no need for a custom cover and no heat loss. Since there are no pop up speakers or moving elements, there is no risk of speakers freezing or accumulating debris in the speaker shaft.

For the total backyard party, two additional patio speakers are included. Entertain guests inside and outside of the spa with your external and internal speaker package.

The patio speakers are mounted on the side of the spa cabinet and can be adjusted separately to control ambient sound. A mounted remote control places control of the music system at your fingertips- inside or outside of the spa! Play your favorite playlists from your Ipod or mp3 player to suit your guests and your mood.


Wow Sound Stereo System

For music on an economical scale, enjoy the WOW sound system from USA Spas. This system features 2 speakers mounted in the spa cabinet. Crank up your favorite tunes on these high quality waterproof speakers - designed to fit in with your spa experience.

Add music to your spa for greater enjoyment. Your spa will be the focal point of your outdoor entertainment area.

Del Ozone QCA Spas ozonator

All USA Spas can be equipped with the Del Ozone Natural Spa Sanitizing System. This system utilizes the lastest ozone technology and injects ozone consisting of three oxygen atoms, directly into the spas plumbing system to kill bacteria in all water lines. The ozone sanitization is completely biodegradable and 100% natural with the only byproduct being oxygen.

Ozone used in combination with a residual amount of Chorine or Bromine can effectively provide a clean, safe bacteria-free spa and dramatically reduce chemical use. The excess Ozone that rises to the spa water surface is recycled by USA Spas' built-in ozone recovery system which most spa manufactures do not offer, to maximizes the sanitization in the spa.

The built in ozonator even comes with a True Ozone indicator light to assure proper functioning of the spa ozonator at all times.

Adding the USA Spas ozone system by Del assures the cleanest, purest water for your spa while also allowing for a reduction in chemicals. Ozone also does its part to eliminate oils, lotions and other contaminants for cleaner spa water.

Ozonator Performance Features include:

    • Water Back Flow Resistant
    • Low EMI Design
    • Longer Life Than CD Chip
    • Increased Ozone Output Over CD Chip
    • Ozone Cell Indicator Lamp
    • Ozone Management System Option
    • Made From All Ozone Resistant Materials

It doesn't get any easier than this. Add technology to your spa by adding a factory installed bromine salt system.

Add the automatic bromine salt system to select USA Spa models when ordering. (cannot be used in combination with an ozonator so for your hot tub sanitizing needs, please select one or the other.)

USA Spas has many patented features. Zone Control™ is a patented flow control system that works two ways, depending on the spa.

For spas that have one pump, Zone Control™ will concentrate the power of the jets on one side of the spa. It will cut off the waterflow on one side, and put all of the power on the other side of the spa. It's just like having the power of two pumps!

For high end spas that already have two or more pumps, Zone Control™ will divide the spa into three sections. You can either have an equal amount of power throughout the entire section of the spa, or concentrate the power of the pumps to one of the three areas of the spa, for an intense hydrotherapy session in one or two seats.

Zoning allows you to direct all the water flow from one of the powerful pumps to a selected Hydrotherapy Seat or even up to 3 seats at one time. This innovative zoning feature provides you with concentrated hydrotherapy and a powerful massage. Prefer a soothing soak? You can also spread out the flow to soften the water therapy.
