Solar Pool Cover, 18 ft Round, 12 Mil PE Bubble

18 ft round solar pool cover helps warm your water by day and hold heat overnight for a longer swim season. This 12 mil bubble blanket uses dense micro-bubbles to capture sunlight and slow heat loss, while also reducing evaporation and keeping wind-blown debris off the surface. Made from durable PE, it’s built for outdoor pools and can be trimmed for a clean custom fit.

• Delivers daytime solar heat gain and nighttime heat retention with dense micro-bubble insulation.


• Fits 18 ft / 5.49 m round pools; cut to size for slightly irregular shapes and edges.


• Helps reduce evaporation to conserve water and slow chemical loss between treatments.


• Blocks leaves, dust, and small debris to keep the pool cleaner with less skimming.


• Stores easily by rolling up; lightweight design makes covering and uncovering faster.

Designed for everyday pool ownership, this heat-retaining solar blanket adds comfort without complicated setup. The heavy-duty 12 mil thickness balances flexibility with tear resistance, making it a practical choice for regular on/off use through changing weather. For longer life, rinse as needed and avoid prolonged exposure to highly chlorinated or acidic conditions. If you want warmer water, fewer refills, and less surface cleanup, grab yours today.
