Customizable Spa and Hot Tub Cover - over your spa from the dust and debris.Save On Local Pick Up 14 Colors Available Price Range $530 $999 Covers are made to last in Arizona's climate. Other covers are made from materials that work well in other regions that do not experience our extreme temperatures. For example, our proprietary vapor barrier lasts when the desert floor heats up to 120 degrees and more. We never use black or blue pigments vapor barriers as they will become brittle and shatter like glass in our dry heat.
