There are definite quality differences in the range of covers you can buy. A sturdy Caldera Spa Cover is designed for maximum energy efficiency. Its tight seal insulates and locks in heat, saving you money on operating costs. Custom-fit to Caldera Spas hot tubs, our covers are tapered for water runoff and are made from durable, marine-grade vinyl. All Caldera covers include child-resistant safety locks and incorporate the mounting plates necessary for attaching our cover lifter systems. Our covers also meet or exceed all ASTM safety standards for UL classification.
