The Solar Spa Cover efficiently captures and retains heat to keep spa water warmer for longer while reducing evaporation and chemical loss. Made from durable, UV-resistant vinyl, it uses a dual-layer design to convert sunlight into usable thermal energy without relying on electricity. Its 5’ circular design is lightweight, easy to handle, and safe, featuring magnets that allow rings to separate quickly if needed. Ideal for energy-conscious spa owners, this cover works well with automatic pool cleaners and offers a cost-effective upgrade to traditional spa covers.
