Freetime Fun Custom Pool Safety Covers for Inground Pool

The Freetime Fun option is designed for any shape pool, including kidney forms. It uses a DIY measuring process to capture exact dimensions, enabling a snug fit with either strong mesh or solid fabric. This is best for buyers who want a tailored safety cover with professional-level coverage. The kit includes measurement guidance and access to expert help through the process, making it suitable for first-time installers and DIY enthusiasts alike.
- Best for: Custom kidney-shaped pools where precise fit is critical for safety and coverage.
- Why selected: Truly flexible to any form; domestic manufacturing supports a tailored solution and ongoing support.
- Limitation: Lead time and form submission are required to produce the exact shape.
VINGLI Pool Cover Set 18 Ft Solar Cover with Reel

This set includes an easy-to-use pool cover roller and a solar blanket designed to fit in-ground pools with varying shapes, including kidney forms. The standout feature is the reel system, which lets a single user roll the cover on and off with minimal effort. It’s well-suited for buyers who want quick, simple operation and a cover that can be adjusted to accommodate non-standard layouts.
- Best for: Kidney-shaped or irregular pools where convenience of removal matters.
- Why selected: One-person rolling, ergonomic crank, and adjustable width support a flexible fit.
- Limitation: The width must be within 18 feet; shape-specific fit is aided but not guaranteed without proper sizing.
Sun2Solar Blue 12 ft x 24 ft Oval Pool Solar Cover

This Oval Solar Cover focuses on heating and evaporation control, using sun-driven warmth to extend swimming time. It’s a compact option that can be advantageous for kidney-shaped pools with shorter lengths or smaller footprints when the pool’s longest dimension aligns with the cover. It helps maintain warmer water overnight and reduces chemical usage.
- Best for: Smaller kidney-shaped pools or sections where a lighter solar cover is sufficient.
- Why selected: Strong emphasis on heat retention and evaporation reduction, with straightforward deployment.
- Limitation: The oval sizing may not perfectly align with all kidney shapes; coverage might be partial in irregular areas.
VINGLI 12Mil Solar Pool Cover (18’x36′ Rectangle)

Although designed for rectangular layouts, this heavy-duty solar cover offers strong heat absorption and evaporation reduction, which can benefit kidney-shaped pools when portions resemble rectangular sections or when a custom fit isn’t feasible. It’s a solid option for larger kidney pools that can accommodate a near-rectangular footprint.
- Best for: Kidney pools with long straight sections or where a rectangular region can be covered efficiently.
- Why selected: Robust 12 Mil construction and good heat absorption support longer swimming seasons.
- Limitation: Not a perfect fit for highly irregular kidney shapes; partial coverage may occur on curves.
20-Ft x 40-Ft Pool Cover for Inground Pools

This premium in-ground winter cover offers heavy-duty construction with extensive sealing seams to keep debris out during the cold season. It’s suitable for kidney-shaped pools with larger footprints that can be approximated to a rectangle for the purpose of covering the main pool area. It provides year-round protection when paired with proper anchoring and storage practices.
- Best for: Larger kidney-shaped pools with more irregular outlines that approximate a rectangular footprint for winter coverage.
- Why selected: Extreme durability and weather resistance with strong debris protection.
- Limitation: Not a perfect fit for highly irregular kidney curves; may require trimming or additional covers for full coverage of curves.
Buying Guide: Key Considerations For Kidney Shaped Pools
- Shape adaptability: Prioritize covers that advertise compatibility with irregular shapes or offer customizable options. For kidney shapes, a truly tailored solution (like a custom safety cover) can provide the most complete coverage and safety.
- Material and durability: Safety covers should use sturdy mesh or solid fabrics. Solar blankets should have durable polyethylene or similar materials with good UV resistance for long seasons.
- Size and fit: If choosing a standard rectangular or oval cover, verify dimensions align with your kidney-shaped footprint. Consider covers that offer adjustable widths or modular components.
- Ease of use: For frequent cover/unwrap cycles, a reel or one-person operation can save time and effort, especially for larger pools with irregular shapes.
- Safety features: For safety-conscious buyers, a rigid safety cover that anchors securely can prevent accidental falls, especially if children or pets share the pool area.
- Energy savings: Solar covers help retain heat and reduce evaporation, which can lower chemical usage and heating costs over time. Assess your climate and insect/leaf load to pick the right option.
- Installation considerations: Some options require professional installation, while others are DIY-friendly. For kidney shapes, measuring accuracy is especially critical for a proper seal and fit.
Frequently Asked Questions
- Are custom pool covers worth it for kidney-shaped pools? Yes, for a precise fit that maximizes safety and minimizes uncovered areas, a custom fit is typically the best option.
- Can a standard rectangular pool cover work on a kidney-shaped pool? It can, but coverage may be uneven and leave portions exposed. Look for covers that offer adjustable or modular sizing.
- Do solar covers fit kidney-shaped pools better than safety covers? Solar covers focus on heat and evaporation control and tend to be easier to deploy, but they do not provide full safety coverage like a dedicated safety cover.
- What’s the main advantage of a pool cover reel for kidney shapes? A reel makes removal and replacement easier, especially when the cover is large or irregularly shaped, reducing manual labor.
- How important is material thickness for winter covers? Higher thickness (12 Mil or higher) typically offers better durability and longer life in cold climates.
- Do I need professional installation for a custom cover? It depends on the product. Custom safety covers often require professional measuring and installation, while some solar covers and reels are designed for DIY setup.
