Winter Swimming Pool Cover for 18 ft x 36 ft Rectangular Pool

In this review the Winter Swimming Pool Cover for 18 ft x 36 ft rectangular pools is assessed for homeowners who need a reliable seasonal cover. The bottom line: this solid, denim blue cover is best for owners in cold climates who want a heavy-duty, low-maintenance winter shield that keeps leaves, dirt and branches out of the water. The biggest reason to buy is the rugged woven, laminated polyethylene construction with a thick black underside coating that resists sunlight degradation and winter wear.

Key Features

• Solid protection: The solid material blocks sunlight and prevents leaves and debris from decaying in the pool over winter.
• Heavy-duty fabric: An 8 x 8 scrim count and 2.36 oz/yd2 material weight give extra strength and tear resistance for harsh weather.
• Large overlap: A 5 ft overlap and loops every 4 ft make it straightforward to position and secure with water tubes.
• Reinforced corners: Metal grommets and reinforced binding at each corner improve durability where stress concentrates.
• Sun protection treatment: The cover is treated to resist sunlight degradation so the color and material integrity hold up season after season.
• Industry-thick underside: The thick black underside coating adds a secondary barrier and helps extend service life.

Who It's For

This cover is aimed at owners of in-ground rectangular pools sized 18 ft x 36 ft (measure inside wall to inside wall) who live in regions with snow, ice, wind or significant debris. It suits people who prefer a solid cover that prevents algae growth by blocking light and who plan to secure the cover with water tubes (sold separately).

Those who need a custom-shaped solution for pools with large protruding steps or irregular layouts should measure the longest length and widest width and may need a larger or purpose-made cover; homeowners who prefer mesh covers for easier water drainage and less ponding should look elsewhere.
