CAL SPAS SHELL

SPA SHELL FEATURES An 8' x 8' spa will weigh about 1,000 lbs. dry. Add 500 gallons of water, four adults and you can imagine the stresses that can be put on the spa. Cal Spa shells are the strongest and sturdiest in the industry--strong enough to be backed with a 10-YEAR structural warranty.
	From value-minded to high-end, every Cal Spas hot tub is built with our EXCLUSIVE FIBERSTEEL CONSTRUCTION PROCESS®, creating the world's strongest spa shells. The finest acrylic sheets are vacuum molded into a particular shape, then reinforced with a skin of coat of resin and fiberglass. After curing for four hours to ensure proper bonding, the shell receives a dense filler coat of resin, fiberglass and fire-retardant aluminum hydrate. Stiffener reinforcement supports and 1-1/4" angled iron are added to principal stress areas to ensure maximum strength. A final filler coat is applied to seal, bond and reinforce the overall structure. The end result of our Fibersteel Construction Process® is the spa industry's strongest and sturdiest shell.
