Fibersteel™ Construction

Durability is paramount with it comes to your home investments. That’s why Cal Spas hot tubs utilize the exclusive Fibersteel™ Construction Process. The finest acrylic sheets are vacuum molded into shape, then reinforced with vinyl ester and fiberglass. After curing, the shell receives a resin filler coat, fiberglass and calcium carbonate. Stiffener reinforcement supports and 1.5 inch angled irons are added to ensure maximum strength. A final filler coat is applied to seal, bond and toughen the overall structure.
