Custom-fit to Caldera Spas, our covers are tapered for water runoff and are made from our durable WeatherPro^® material. All Caldera covers include child-resistant safety locks and incorporate the mounting plates necessary for attaching our hot tub cover lifter systems.

Our covers also meet or exceed all ASTM safety standards for UL classification.
