Outdoor Hot Tub Cover - 16-mil Thermal Blanket for Round Hot Tubs (7 FT Dia)

About this item

• Additional benefits of using the round solar cover on the hot tub include reducing water evaporation by up to 95%, preserving water temperature, and absorbing solar heat to minimize future heating time.
• 16 MIL Thickness: Different from the general 8-12 mil spa hot tub solar blanket, we use a thicker material of 16 mil, which has better heat preservation and water retention effect, the bubbles will not crack or fall off, and the round solar cover can be used for a long time.
• Save Time & Money: When you heat the water in your hot tub, putting our thick bubble hot tub cover on it can greatly shorten the heating time, and it also saves you money to some extent. Besides, using the blanket cover can effectively cut down the condensation on your hot tub cover.
• Trim to Fit: Our thermal solar blanket cover is 7ft in diameter and fits most inflatable round style hot tubs. If your tub has more irregular shapes, you can put the cover over the hot tub first, then make a mark and cut along the mark.
• Bubble-side Down: When using, you need to put the bubble side of the solar blanket for hot tubs close to the water surface, with the smooth side facing up, which can also play a role in preventing dust, reducing condensation and freezing on the edge.
