Transform Your Spa Experience with Ultimate Cover Protection

Your hot tub cover is one of the most important investments in your spa's longevity and energy efficiency. The Premium Spa Cover Cap 89″×89″×12″ by Hot Tub Things delivers professional-grade protection that extends the life of your spa cover while reducing maintenance and replacement costs.

What Is a Spa Cover Cap?

A spa cover cap (also called a hot tub lid protector or spa cover shield) is a protective layer designed to shield your spa cover from UV rays, harsh weather, tree sap, bird droppings, and environmental debris. This medium hot tub cover protector fits covers measuring 89 inches by 89 inches with a 12-inch skirt depth, making it ideal for most square and near-square spa configurations.

Unlike cheap vinyl covers that crack and fade, our premium spa cover cap features reinforced stitching, UV-resistant materials, and weather-sealed seams that stand up to years of outdoor exposure.

Frequently Asked Questions

  • Measure your existing spa cover from edge to edge. This cap fits covers that are 89″ × 89″ with up to a 12″ skirt depth. If your cover is within 2-3 inches of these dimensions, this cap should provide adequate coverage. For best results, measure your cover's length, width, and the depth of the sides before ordering.
  • Absolutely! UV rays are the #1 cause of spa cover deterioration, leading to cracking, fading, and loss of insulation. A quality cover cap blocks harmful UV radiation and protects against environmental damage, potentially extending your cover's lifespan by 2-5 years. Many customers report their covers lasting twice as long when protected with a cap.
  • Simply remove the cap and machine wash it on a gentle cycle with mild detergent. Air dry or tumble dry on low heat. For spot cleaning, use a soft brush with soapy water. We recommend cleaning your cover cap 2-3 times per year or as needed to remove accumulated debris.
  • No, you should remove the cover cap before removing your spa cover to access your hot tub. The cap is designed to protect your cover when the spa is not in use. The easy slip-on/slip-off design makes removal quick and convenient.
  • Yes, this premium cover cap features waterproof construction with sealed seams to prevent moisture penetration. This keeps your spa cover dry and prevents water damage, mold, and mildew growth that can compromise your cover's insulation and structural integrity.
  • Our premium spa cover cap uses commercial-grade, UV-resistant fabric with reinforced stitching and quality hardware. Cheaper caps often use thin vinyl that cracks within months, weak elastic that loses tension, and poor stitching that fails in wind. This cap is built to last multiple seasons with proper care.
