Improve heat retention and lower energy costs with an 8 mil Hot Tub & Spa Solar Cover, designed to sit directly on the water surface beneath your existing cover. Made from durable resin bubble material, this solar blanket uses thousands of air-filled bubbles to capture heat and significantly reduce heat loss between soaks.

Measuring 6 ft x 6 ft, this solar cover is ideal for most square hot tubs and spas and can be trimmed for a custom fit. It helps reduce water evaporation by up to 95%, keeping water levels stable while saving on chemicals and refill costs. By retaining heat more effectively, the solar cover reduces heater run time, helping extend the life of your hot tub equipment while saving money year-round.

An affordable and easy upgrade, this hot tub solar blanket works alongside your existing cover to maximize efficiency and comfort.
