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.

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.

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.
