Shop Square 18 ft Round Winter Pool Cover — Navy Blue Mesh, Heavy-Duty, With Winch & Cable

Shop Square's 18 ft round navy blue winter pool cover is a heavy-duty, mesh above-ground cover engineered to protect your pool from debris, precipitation and snow while withstanding extreme cold.

If you want a durable, easy-to-fit solution to keep your 18 ft round above-ground pool clean through winter, this cover combines reinforced mesh, heat-sealed seams and a weather-resistant coating for season-long defense. It arrives with a vinyl-coated cable and a tightening winch so you can secure the cover quickly and keep leaves and runoff out of the basin. Designed with a three-foot overlap and rip-proof metal grommets, the cover is sized to sit properly over most standard 18 ft round setups.

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

The cover uses a high-strength polyethylene scrim reinforced mesh that resists tears and stretching under load. A durable coating and heat-sealed seams add water-shedding and UV-resistant properties so the material keeps its integrity across cold months.

• Industry-grade polyethylene scrim for tensile strength
• Coated mesh resists water absorption and reduces snow buildup
• Heat-sealed seams prevent fraying and edge failure
• Rated to tolerate temperatures down to −10°F (−25°C)

What makes installation quick and secure?

The cover ships with clear, easy-to-follow instructions and the hardware needed to fasten it tautly around the pool. Rip-proof metal grommets spaced every 30 inches accept the included vinyl-coated cable, and the tightening winch lets you adjust tension without specialized tools.

• Heavy-duty vinyl-coated cable included for perimeter fastening
• Tensioning winch allows simple, even tightening
• Metal grommets spaced 30 inches apart for consistent hold
• Three-foot overlap ensures full coverage for most 18 ft round pools

Will this cover help reduce maintenance and sun damage year-round?

Yes — the mesh construction keeps out leaves and large debris while allowing rainwater to drain, limiting the amount of contaminants entering the pool. The coated surface and UV-resistant material also help protect the pool interior from seasonal sun degradation when you use it beyond strict winter months.

• Mesh filters out debris while allowing controlled drainage
• Coating and UV resistance reduce material breakdown from sunlight
• Less debris means reduced cleaning and fewer chemical adjustments

How do I know this will fit my pool correctly?

This cover is custom-sized to fit 18 ft round above-ground pools and includes a three-foot overlap to accommodate different wall heights and rail profiles. Measure your pool diameter at the widest point and compare it to the product dimensions; the overlap gives extra material for a snug, protective fit.

• Designed specifically for 18 ft round above-ground pools
• Three-foot overlap for secure coverage and easier attachment
• Grommets and cable allow adaptable tensioning across different pool rims

Who is this for: Homeowners with an 18 ft round above-ground pool who need a robust, fuss-free winter cover that balances strength and drainage. It's suited for yards exposed to heavy leaf fall, periodic snow, or prolonged sun exposure and for anyone who wants an installation process that doesn’t require specialty tools or professional mounting.
