In 1993, our covers were first tested by an independent lab to comply with the ASTM Safety Standard. All models passed and Sunstar was the first spa cover manufacturer to offer a safety labeled cover. In 1994, Sunstar was the first to receive UL Classification and our covers are the only spa covers classified for ASTM Safety on all sizes, densities and models, even swim spas.

You can feel confident that Sunstar builds a spa cover which is favored by safety code officials nationwide. We are proud to offer the UL Classification mark on our covers.
