Protect Your Pool This Winter with Confidence

The Winter Block 18' Round Pool Cover is built for more than just cold weather. It combines robust weight and thoughtful engineering to guard your above-ground pool against wind, debris, and the whims of winter, while making spring cleanup simpler and less time-consuming.

Premium Construction for Enduring Performance

Made from laminated polyethylene with a thick 8x8 scrim and high-density stitching, this cover is designed to stand up to season after season of exposure. The material is UV-treated to help maintain strength and color, so the cover stays protective year after year.

  • Thicker, more durable than standard winter covers
  • 8x8 scrim weave with high-density stitching for reliability
  • UV-treated to resist sun damage and extend life

Easy to Install, Ready Out of the Box

Lightweight enough for convenient handling, the cover comes with perimeter grommets, a steel cable, and a winch, so setup is straightforward right away.

  • Lightweight handling supports quick seasonal setup
  • Perimeter grommets provide secure anchoring
  • Winch and steel cable enable fast, tensioned installation

Keep Debris Out, Weather in Check

Designed to block leaves, rainwater, and melted snow, this cover helps keep the pool area tidy and reduces the usual spring debris buildup, making re-opening easier.

Size, Fit, and What You Get

Specifically crafted for 18' round pools, the cover measures 21' in diameter to overhang the edges for secure coverage. The blue color adds visibility, while the included hardware ensures a complete setup.

Durability, Weatherproofing, and Peace of Mind

Winter Block backs this model with an 8-year warranty, signaling a focus on long life and dependable performance. While results can vary by environment, the design aims to endure cold temperatures and UV exposure.
