Inground Pool Safety Cover 18ft x 36ft Rectangle - Heavy Duty Mesh

Our review of the Happybuy inground pool safety cover finds it best for homeowners who need a durable winter solution that prioritizes safety and debris control. The single biggest reason to buy is its combination of a tight woven mesh and heavy-duty construction - the cover passes water while blocking leaves and sunlight, reducing algae and evaporation and providing a strong, child- and pet-safe barrier for an 18' x 36' pool.

Key Features

• Size and fit: The cover is sized 20' x 38' to suit an 18' x 36' pool, giving a 2' overlap so the material does not stretch and stays secure around the pool perimeter.
• Material strength: Made from high-strength polypropylene with double strapping and triple stitching, the cover resists aging, abrasion and high temperatures for long service life.
• Drainage design: Tight mesh construction lets water pass through for effective drainage while blocking leaves, snow and debris so the pool stays cleaner over winter.
• Safety certified: Certified to ASTM Standard F1346 and engineered to act as a solid tensile barrier to help prevent accidental drownings of children and pets.
• Complete hardware: Includes brass anchors, stainless-steel springs and installation tools with adjustable rope lengths to simplify permanent anchoring into concrete.
• Warranty: Backed by a 15-year warranty, indicating manufacturer confidence in long-term performance.

Who It's For

Homeowners with a rectangular inground pool about 18' x 36' who want a robust winter cover that balances safety and debris control will appreciate this model. It is also a sensible choice for properties where anchors can be permanently installed in concrete and where minimizing water evaporation and algae growth through reduced sunlight is a priority.

Those who need a cover for an above-ground pool, pools with nonstandard shapes, or who cannot install drill-and-tamp anchors should look elsewhere. Also, if immediate snow-melting or rapid water removal is a priority, a solid non-mesh cover would perform differently than this mesh design.

Pros & Cons

Pros

• Robust polypropylene fabric with triple stitching and double strapping gives clear durability benefits for seasonal protection.
• Tight mesh both drains and blocks debris while limiting sunlight to slow algae growth.
• Comes with brass anchors, stainless springs and tools so installation is complete with the package.

Cons

• Permanent drill-and-tamp brass anchors require concrete installation, which may not suit renters or non-concrete decks.
• Mesh allows water through, so heavy snow or pooled water still requires monitoring and possible removal in extreme conditions.
