The shell of all Sunspa spa models is from the Aristech Acrylics brand. Aristech is one of the largest and most prominent companies in the field of acrylic tubs.
After the molding process, Aristech tubs are provided with a special vinyl ester layer and then a polyester reinforcing underlay. This layer is built up from several layers until the tub has become a self-supporting whole, making deformation impossible. The cockpit is later mounted in a stainless steel frame or is fitted with a plastic frame, which is also the bottom plate.
The material of the acrylic tubs consists of several layers of woven glass fiber in combination with compact urethane insulation. This combination results in an incredibly strong structure that is resistant to scratches, water and all kinds of weather influences.
The acrylic color is fully incorporated so that no wear spots can occur and the color will still look like new after years. Thanks to the smooth surface of the tub, it is also very easy to clean.
