Triple Bond Acrylic Shell White

TRIPLE-BOND ACRYLIC SHELL

THE STRENGTH
TO LAST A LIFETIME

The quality of your hot tub’s shell has a lot to do with how long it will last. The shell is the shaped form inside the hot tub that you sit in every time you use your hot tub, so it has to be durable and easy to maintain. Strong’s acrylic hot tub shell is a triple-bond design and provides effortless, long-lasting luxury. The acrylic hot tubs are manufactured with a three-layer construction process that produces the industry’s strongest shell.

PREMIUM QUALITY
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.
