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

 They keep their good looks backed by a 10 year guarantee*. QCA has a hot tub to fit your needs – from a cozy 2 person spa to an 8 person party tub. 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. 


QCA 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 QCA Spas 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. *Shell warranty applies to Jewel, Performance, Majestic and Paradise Series QCA Spas.
