This 84" by 84" hot tub cover is a Master Spa Factory OEM replacement (SKU: X454777). Get the right fit without the guesswork.
Please Note: This cover fits other makes of Master Spa, and is the standard at 84" x 84" with a 6" radius.
This cover is extremely energy efficient, as it's made of a 1.5-pound foam density, six-inch thick foam insulation (which tapers to 4-inches along the sides), and a full-length heat seal. It has been upgraded to include two rubber grip handles and is made of a high quality marine-grade vinyl covering that is mildew treated and unfazed by UV rays.
