Robelle 18 ft Winter Pool Cover for Above Ground Pools — Extra Heavy-Duty Solid Cover, 12x12 Scrim & Winch Included

The Robelle 18 ft Professional Supreme Winter Pool Cover is an extra heavy-duty solid winter cover designed to protect 18-foot above-ground pools from snow, ice, and debris during the off-season.

Built with a dense 12 x 12 scrim and heavyweight polyethylene, this solid winter cover blocks water passage and resists winter wear. It provides a robust barrier between your pool water and the elements, includes a four-foot overlap to simplify installation, and ships with a winch and cable for perimeter attachment. Robelle’s Professional Supreme line is engineered for durability and backed by decades of experience in pool closing products.

How does this cover stand up to winter weather and ice?

The Robelle Supreme is a solid cover that prevents water from passing through the fabric, keeping rain and melting snow from entering the pool. The extra-heavy polyethylene material and 12 x 12 scrim increase tear resistance and help the cover resist punctures from ice and debris.

• Solid, non-permeable fabric prevents surface water infiltration.
• 12 x 12 scrim woven for improved tensile strength and durability.
• Material weight of about 3.26 oz/yd² (professional-grade heavy polyethylene).
• Designed to float loosely on water to reduce stress from ice movement.

What comes in the box and how do I install it?

The package includes the 18 ft cover with a standard four-foot overlap, plus a winch and cable to secure the cover through the grommets. Installation involves draping the cover over the pool, hooking the cable through perimeter grommets, and tightening the winch; optional cover clips or wrap can be added for extra hold.

• Included winch and cable for perimeter attachment through grommets.
• Four-foot overlap simplifies positioning and provides extra coverage.
• Recommendation: go one size up if your pool has an oversized top rail.
• For decks, place vinyl water weights on top of the cover where needed.

How durable is the Robelle Supreme compared with other covers?

This model is built substantially heavier than many industry standards, combining a high scrim count with a thick polyethylene finish. Robelle highlights long-term performance with a 15-year warranty, reflecting the product’s reinforced construction and resistance to seasonal wear.

• Constructed about 85% heavier than typical covers for longer life.
• 12 x 12 scrim count improves tear resistance and overall strength.
• Backed by a 15-year warranty for added homeowner confidence.
• Solid design reduces maintenance tasks during spring opening.

Will this cover work for my above-ground pool layout?

The cover is intended for traditional above-ground pools with a standard top rail and is sized by pool diameter. Because the product includes a four-foot overlap, order by your pool size and consider selecting a larger size if rails or deck features create clearance concerns.

• Designed for conventional above-ground pools with top rails.
• Includes a 4 ft overlap; listed size equals pool diameter (cover spans 22 ft including overlap).
• Not intended as an in-season debris cover—meant for winter/off-season use.
• Ice equalizer pillow and additional securing accessories sold separately.

Who is this for? Homeowners with 18-foot round above-ground pools who want a heavy-duty, solid winter cover that keeps winter precipitation and debris out of the pool. It’s best for users who prefer a low-maintenance winter solution, need a cover that tolerates high winds, and value durability—especially if you have moderate-to-severe winter weather and want a professional-grade product backed by a long warranty.
