Built To Last For a Lifetime

The durability of your hot tub’s shell is key to its longevity and overall performance. As the part you interact with every time you use your spa, the shell must be both strong and easy to maintain. Strong Spas’ acrylic hot tub shells are crafted with a triple-layer bond, offering unparalleled strength and lasting luxury. This three-layer construction process creates the industry’s most durable shell, ensuring your spa provides years of relaxation and enjoyment with minimal maintenance.

Premium Crafted Shells

Hot tub shell production begins with a genuine Lucite™ Xtra acrylic sheet, a non-porous material that won’t harbor bacteria. This layer is laminated with a vinylester bonding layer that acts as a vapor barrier. The third hot tub layer is our revolutionary StrongBond® polyurethane component, which has superior strength compared to traditional fiberglass materials.

Industry-Leading Warranty

At Strong Spas, we stand behind the quality of our StrongBond reinforced acrylic shell with an industry-leading warranty. This ensures not only a sleek, luxurious appearance but also the long-term durability and peace of mind you deserve. Our spas are built to last, providing years of enjoyment backed by exceptional coverage. Our shells have superior strength compared to traditional fiberglass.

A Shell Free from Harmful VOCs

Unlike traditional fiberglass shells, Strong Spas’ Triple-Bond Acrylic shells are free from harmful VOCs like styrene, a neurotoxin found in fiberglass. Our innovative, eco-friendly shell reinforcement protects both our customers and employees by eliminating toxic emissions. Enjoy a spa experience that is safe, clean, and odor-free, without compromising on strength or quality.

Triple-Bond Quality and Longevity

Strong Spas’ unique Triple-Bond Acrylic shell uses an advanced ABS-backed acrylic sheet that is both chemically and mechanically bonded to prevent permeation and the formation of bubbles. This innovative process ensures the shell is resistant to delamination, providing unmatched durability and a seamless, worry-free spa experience for years to come.
