Choosing the right cover for a kidney shaped pool is one of the most practical investments a pool owner can make. Beyond the obvious function of keeping the water clean, a proper cover significantly impacts safety, chemical efficiency, and the overall maintenance burden. Because the unique contours of a kidney shape create specific challenges, however, a standard rectangular cover will not suffice.
The market is flooded with options ranging from simple mesh drops to complex automatic systems, making the selection process overwhelming. To find the best pool cover for kidney shaped pool setups, one must look past aesthetics and evaluate the specific mechanisms of fit, material durability, and ease of operation. This guide breaks down the essential factors to navigate the decision with confidence.
Understanding the Kidney Shape Challenge
The primary difficulty with kidney shaped pools lies in their non-linear design. Unlike rectangular pools that allow for straightforward, rolling covers, the varying width and curved edges of a kidney shape require a more sophisticated approach. The cover must contour precisely to the narrow waist and wider ends to prevent sagging or gaps where debris can enter.
Furthermore, the location of the drive mechanism matters significantly. Whether the system is mounted on the side or the end, the cover must distribute tension evenly across the irregular surface. Failure to account for these geometric nuances results in a cover that is difficult to pull tight, prone to tearing, or unsafe due to pooling water in the center.
Manual Covers: The Reliable Standard
For many owners, the best pool cover for kidney shaped pool configurations is a high-quality manual reel system. These systems involve a heavy-duty tarp connected to a rotating spindle, allowing the user to roll and unroll the cover with moderate physical effort. The primary advantage of this method is the direct control it offers over tension and alignment.
When selecting a manual cover, prioritize reels with robust aluminum frames and marine-grade vinyl or polypropylene fabrics. Look for features such as sealed bearings in the rollers and ultraviolet inhibitors in the material to prevent fading and degradation. While it requires storage space and physical labor, the manual system is often the most cost-effective and reliable long-term solution for irregular pool shapes.
Automated Systems: The Pinnacle of Convenience
Homeowners seeking the highest level of convenience often gravitate toward automated pool covers. These systems utilize a powerful motor housed near the pool deck, which retracts and extends the cover at the push of a button. For kidney shaped pools, this technology is particularly valuable, as it eliminates the strenuous work required to tension the irregular surface.
However, automation comes with specific prerequisites. The pool layout must accommodate the track system, and the water table in the surrounding area must be stable to prevent ground shift that misaligns the mechanism. While the initial investment is higher, the seamless integration of an automated cover with a kidney shape provides a luxurious and time-saving experience that justifies the cost for many.
Safety and Security Considerations
Safety is arguably the most critical factor when determining the best pool cover for kidney shaped pool environments, especially for households with young children or pets. Modern safety covers are engineered to withstand significant weight and resist punctures, preventing accidental falls through the water surface.
- Certification: Look for covers that meet ASTM International standards for safety performance, often labeled as "Safety Pool Cover."
- Barriers: Ensure the cover creates a continuous barrier around the entire perimeter, with no gaps where a small body could slip through.
- Drainage: A safe cover incorporates slight gaps or drainage ports to prevent dangerous water pooling on top, which could trap debris or freezing rain.
Material Durability and Weather Resistance
The longevity of a kidney shaped pool cover is directly tied to its resistance against the elements. Constant exposure to sun, rain, and fluctuating temperatures will break down inferior materials quickly. Therefore, the best pool cover for kidney shaped pool installations is built to last.
Vinyl covers offer a classic appearance and are generally thicker, providing better insulation against heat loss. Polyethylene covers, on the other hand, are lighter and excel in shedding dirt and resisting mildew. Regardless of the surface material, the stitching and hems must be double-stitched to withstand the stress of the irregular shape without ripping at the curves.
Maintenance and Longevity Tips
Even the most durable cover requires proper care to maintain its functionality. Regular cleaning to remove debris and washing with mild soap prevent the buildup of mold and algae, which can degrade the material over time. When storing the cover for the off-season, folding it carefully while dry ensures the fabric retains its memory and flexibility.
Additionally, inspecting the cover for tears or seam separation at the start of each season allows for quick repairs. Addressing small issues immediately prevents them from becoming large problems that necessitate a full replacement, ensuring your kidney shaped pool remains secure and efficient year after year.
