Many consumers mistakenly believe that an acrylic spa hot tub is entirely made of "pure acrylic," but this is not actually the case. Acrylic spa hot tubs are not entirely made of acrylic; they are a composite of two materials: 1. Surface layer: Sanitary grade acrylic sheet 2. Backing reinforcement layer: Fiberglass reinforcement layer
