12x18 ft Rectangular Pool Cover with Side Storage - Solar, Drainable

Our review of the 12x18 ft Rectangular Pool Cover finds it best suited for owners of rectangular or oval above-ground pools who want a durable, easy-to-fit solar-style cover that prevents waterlogging and resists UV damage. The single-piece cover uses 420D color woven polyester with a triple PU coating and a central open/close drain, so the biggest reason to buy is its practical blend of weather resistance and built-in drainage that keeps standing water off the cover and helps retain pool heat.

Key Features

• Material: 420D color woven polyester with high color fastness and anti-UV properties keeps the cover looking good and helps warm pool water.
• Drainage: Built-in open/close drain at the center reduces water accumulation and lets you attach a 1 in water pipe for reliable runoff.
• Tensioning system: Diagonal Double Tensioner device and dual nylon webbings deliver a strong, adjustable fit that resists wind and supports at least one adult standing on the cover.
• Waterproofing: Triple PU coating WP10000+ kPa plus double-stitched seams and waterproof taped joints prevent rain and dirt from entering the pool.
• Side storage: Four side organizer straps let the cover be attached to the pool side for easy access and tidy storage when not in use.
• Compliance and safety: Fabric complies with REACH EU environmental standards and does not produce harmful substances after sun exposure.

Who It's For

This cover is ideal for owners of rectangular or oval above-ground pools who want a robust, all-in-one solar cover with built-in drainage and strong tensioning. It is also a sensible choice for those who value easy attachment and occasional in-ground pool use or an outdoor shade solution.

Customers who need a custom-sized cover, a lightweight mesh winter cover, or a product that includes a complete fixed component kit out of the box should look elsewhere; the fixed component kit and some drainage accessories are offered separately.
