Robelle 18 ft Winter Pool Cover for Above Ground Pools — Solid 14x14 Scrim, 5.2 oz/yd² Charcoal

The Robelle 18 ft Ultimate Winter Pool Cover is a premium solid winter cover designed to protect 18-foot round above-ground pools from snow, ice, and debris throughout the off-season.

When you need a long-lasting, no-drain winter solution for a traditional above-ground pool, this Robelle cover combines dense woven construction and heavy material weight to resist tearing, punctures, and winter stress. Made with a 14 x 14 scrim and 5.2 oz/yd2 polyethylene, the cover offers a solid barrier that sits over the water rather than allowing moisture to pass through. It ships with a winch and cable for perimeter attachment and includes a generous four-foot overlap to simplify installation around standard top rails.

How strong is the material and what does that mean for durability?

The cover uses a high-scrim woven polyethylene and a heavier-than-average fabric weight, which together increase resistance to abrasion and wind stress. Higher scrim counts mean more threads per inch, and 5.2 oz/yd2 material weight contributes to longevity compared with standard covers.

• 14 x 14 scrim woven construction for tear resistance
• 5.2 ounces per square yard (176 g/m²) material weight for durability
• Constructed 160% heavier than industry standard for extended life
• 20-year warranty backing quality and manufacturing

Will this cover keep winter water and debris out of my pool?

This is a solid winter cover, so water and debris do not pass through the fabric. It floats on the pool surface, blocking leaves, twigs, and direct snowfall from entering the pool while helping to reduce winter maintenance tasks.

• Solid, non-porous fabric blocks debris and sunlight
• Charcoal topside and black underside help hide dirt and reduce UV exposure
• Designed to float loosely on water—minimizes stress on seams
• Not intended for season-long debris use during swim season

How is the cover installed and secured for windy or decked pools?

Robelle includes a winch and cable for fastening through the cover’s grommets around the perimeter, which is the recommended installation method. For pools with decks, the cover can be installed over the deck using vinyl water weights or by running cable under the deck where possible; additional clips or wrap are available separately for extra security.

• Included winch and cable secure cover through perimeter grommets
• Four-foot overlap (22 ft total material) simplifies fitting over top rails
• Use vinyl water weights on decks or water bag weights for added hold
• Cover clips and cover wrap sold separately for enhanced anchoring

Will this fit my pool and what should I consider before ordering?

Order by your pool size and account for the four-foot overlap built into the cover dimensions. If your above-ground pool has unusually large top rails or raised decking, you may want to choose the next size up so the fabric can float freely without excess tension.

• Designed for traditional above-ground pools with standard top rails
• Four-foot overlap helps clear rails and eases installation
• Choose larger size when top rails are especially tall or wide
• Not intended as a seasonal debris cover—use only for winter closing

Who is this for: The Robelle 18 ft Ultimate Winter Pool Cover is aimed at above-ground pool owners who want a long-lasting, solid winter closing solution backed by decades of pool-cover experience. It suits people who prioritize strength, easy installation with included hardware, and a cover that reliably blocks winter debris and snow. Choose this cover if you have a traditional 18-foot round pool and want a heavy-duty option that minimizes offseason maintenance and stands up to wind and winter stress.
