Winter Pool Cover 18 ft Round for Above Ground - Extra Thick

Our review of the Winter Pool Cover 18 ft Round for Above Ground finds it best suited to pool owners who need a heavy-duty seasonal cover that prioritizes material strength and weather resistance. The single biggest reason to consider this cover is its construction: a 14 x 14 scrim count and 185 GSM density combine with reinforced seams and metal grommets to create a durable barrier that keeps pool water clean through winter. This review focuses on real-world use: installation, durability, and whether the claimed cold and UV resistance hold up in a typical backyard winter.

Key Features

• Extra thick construction: The 14 x 14 scrim count and 185 GSM density provide a robust, puncture-resistant surface that helps the cover resist tears and hold up to debris.
• Reinforced seams: Well-constructed seams reduce the chance of dirt or small debris entering the pool while the cover is in place.
• UV protection: LDPE coating on the top surface provides protection from winter sunlight and prolonged UV exposure to slow material degradation.
• Cold resistance: Rated to perform in very low temperatures, the cover tolerates cold down to roughly 10 F and heat up to about 180 F without obvious brittleness.
• Secure fastening system: A steel-core cable runs through reinforced metal grommets and is tightened with a molded winch for a snug, stable fit around the pool.
• Generous overlap: The 4 ft overlap simplifies installation and helps keep the perimeter secured even on uneven ground or slight size variations.

Who It's For

This cover suits owners of above-ground round pools who want a long-lasting winter solution that emphasizes durability and secure attachment. It is particularly appropriate for climates with cold winters and for people who prefer a heavier cover that resists wind and debris rather than a lightweight tarp.

It is less suitable for those who need a very lightweight, low-cost temporary cover or for buyers who expect included accessories like pool pillows; the pool pillow is sold separately. Shoppers on a strict budget or with unconventional pool shapes should evaluate alternatives.

Pros & Cons

Pros

• Heavy-duty material and high scrim count result in a sturdy, long-wearing cover.
• LDPE coating and black underside reduce UV damage and discourage algae growth.
• Steel-core cable, reinforced grommets, and molded winch deliver a secure installation.

Cons

• Some users report variable longevity-while many find it lasts multiple seasons, others have noted early wear, so real-world lifespan can vary.
• The product does not include a pool pillow, which is often purchased separately for freeze protection.
