10 Best Swimming Pool Solar Covers 2025 in the United States

This Real Relax solar pool cover is designed to help pool owners save on heating costs by capturing and transferring solar heat into the water, thanks to its bubble design with the bubbles meant to face down. Made from durable 16 mil thick polyethylene, it offers good strength and resistance to tearing, promising a longer lifespan. Its blue color helps absorb sunlight while also keeping the pool looking clean and bright. Sized at 20 by 40 feet, it suits most rectangular inground or above-ground pools, and you can easily trim it to fit other shapes if needed. The cover also reduces water evaporation by up to 95%, helping to conserve water and reduce chemical loss. Another plus is its UV resistance, which protects it from sun damage and extends its usability.

On the downside, the cover is quite heavy at 61 pounds, so handling it might be a bit cumbersome during installation or removal. Also, while it fits rectangular pools well, irregular pool shapes will require careful cutting for a proper fit, which could be tricky for some users. This solar blanket represents a solid choice for anyone wanting a reliable, heat-retaining pool cover that also keeps debris out and lowers maintenance needs.

The BigXwell Solar Pool Cover is a durable and effective option for maintaining your pool's temperature. Made from high-quality polyethylene (PE) material, this cover is designed for longevity and can withstand harsh weather conditions. Its 16-mil thickness and blue color help maximize heat retention by trapping solar energy using thousands of thermal bubbles. This design not only heats your pool during sunny days but also retains the warmth during cloudy days or chilly nights, ensuring a comfortable swim regardless of the weather.

The cover also significantly reduces water evaporation by up to 95%, which is beneficial for water conservation and reducing the need for frequent refills. Measuring 16 x 32 feet, it fits rectangular in-ground pools but can be trimmed to suit pools of various shapes and sizes, making it versatile. However, at 50.9 pounds, it might be a bit heavy for some users to install or remove without assistance.

Its floating installation type is simple, although it requires regular manual care, such as hand washing with mild detergent and air drying.

The VEVOR Solar Pool Cover is a solid choice if you want to keep your swimming pool warmer and reduce water evaporation. Made of durable 12 mil thick polyethylene with a blue color and bubble design, it traps heat effectively—raising your pool water temperature by up to 15°C in ideal conditions. This can help extend your swimming season and lower heating costs. The bubble pattern is also great for reducing evaporation, saving water, and cutting down on pool cleaning since it helps keep debris out.

Its rectangular shape (32 by 16 feet) fits many pools and can be trimmed for a custom fit, which adds flexibility if your pool isn’t a perfect rectangle. The material is strong and resists sun damage, so it should last without fading or tearing easily. However, being a floating cover, it might not be the best if you want something that completely seals the pool surface. Also, its size means it’s better suited for medium to large rectangular pools.

This solar cover provides a practical and affordable solution for pool owners who want simple, effective heat retention and water conservation without complex installation.
