Sun2Solar Blue 18×32 Solar Cover (1200 Series)
This 18 ft by 32 ft rectangle solar cover is designed to maximize heating while minimizing evaporation. The 1200 Series uses bubble blanket technology to trap heat from the sun, potentially raising water temperatures by up to 15 degrees. By reducing evaporation, it helps conserve water and chemicals, and it continues to retain warmth after sunset for overnight comfort. Installation is straightforward, with a snug fit that supports efficient heat capture. This option is ideal for rectangular inground and above-ground pools looking to leverage solar energy.
Robelle 18 x 33 ft Heavy Duty Winter Cover (Overlap Included)
This heavy-duty winter cover is sized for 18 x 33 ft oval pools with a 4 ft overlap, translating to a 22 x 37 ft overall size when fully laid out.

Evaporation reduction remains a core benefit, helping to conserve water and minimize chemical usage during the swimming season and transitions between uses.
Buying Guide: Key Purchase Considerations
- Size and fit: Confirm the pool dimensions and overlap needs. Some covers are sized to fit 18 x 32 ft exactly, while others include extra overlap for easier installation and better seam integrity.
- Heat retention versus safety: Solar covers prioritize heat gain and evaporation reduction, while safety covers emphasize secure enclosure during winter. Choose based on climate, pool usage, and safety requirements for the space.
- Material and durability: Look for scrim density (the weave) and material weight per square yard. Heavier scrim and thicker polyethylene typically offer longer lifespans and better resistance to tearing.
- Overlap and hardware: Overlaps (e.g., 4 ft) help with installation and durability. Some options come with winches and cables, which simplify setup and tension maintenance.
- Weather and climate considerations: In colder regions, a robust winter cover with ample overlap can prevent debris buildup and provide winter protection. In sunny climates, solar covers that maximize heat capture may reduce heating costs.
- Warranty and service: A longer warranty often signals higher durability. Manufacturers with decades of pool expertise can provide ongoing support for repairs and replacements.
- Installation and maintenance: Consider ease of removal for use days, cleaning requirements, and whether the cover supports safe removal with minimal risk of tearing or warping.
- Transparency of claims: Evaluate heat gain estimates and evaporation reductions in real-world conditions. Some features are tested under specific lab conditions that may differ from home-use results.
- Installation accessories: Look for included winches, cables, and installation guides to reduce setup time and ensure consistent tension across the surface.
Choosing the right 18 x 32 pool cover involves balancing heat gain, durability, and ease of use. A solar cover is often ideal for homeowners seeking energy savings and warmer water, while heavier winter covers emphasize protection and longevity for off-season care. Warranty coverage and the clarity of installation instructions are practical indicators of long-term value. By comparing overlapping coverage, material quality, and compatibility with your pool’s shape, you can select a cover that delivers consistent performance across seasons.
