It features a durable 25 gauge vinyl material, which is hand-folded to minimize creasing. The liner uses a unibead style, offering flexibility during installation, whether your pool requires overlap or beaded styles. However, it is not suitable for pop-up pools.

The liner boasts a visually appealing blue rock and swirling water design that can enhance the look of your pool area. Measuring at 52 inches in wall height, it fits flat-bottom pools perfectly and includes a universal gasket kit for the pool’s skimmer and return, which can help prevent corrosion and leaks. Potential buyers should carefully double-check their pool measurements before purchasing to ensure compatibility.

Proper installation requires laying the liner out in the sun for at least an hour to warm up the vinyl, which might be an inconvenience for some users. Despite these minor drawbacks, the liner provides good value for its durability and aesthetic appeal, making it a solid choice for those looking to upgrade their above-ground pool.

The Boulder Swirl pattern—blue rocks over swirling water—is visually appealing and adds a refreshing look to your pool.

This liner uses an overlap style, meaning it drapes over the pool walls and is secured with coping strips, which generally makes installation straightforward if you have a compatible flat-bottom pool with 48" or 52" walls. However, it’s not suitable for pop-up pools. The liner is hand-folded to help avoid creases and works best if warmed in the sun before installation. It comes with a 20-year limited warranty, which shows the manufacturer’s confidence in durability.

It is specifically sized for 27 ft round pools, so if your pool shape or size differs, this liner won’t be a good match.

Be sure to measure carefully and follow installation tips for the best results.

However, it is incompatible with Intex or pop-up pools, which limits its applicability in some cases.

The liner features a pleasing blue marble tile pattern, which can add a classic yet stylish look to your pool. This aesthetic appeal aligns well with those seeking a beautiful backyard ambiance. It is recommended to warm the liner under the sun before installation, which can be an extra step for some users but ensures a smoother fit without creases or wrinkles.

The included universal gasket kit is a practical addition, offering protection for your pool's skimmer and return areas, which is key for preventing corrosion and leaks over time. This is a thoughtful inclusion, providing longevity to both the liner and the pool structure.

Potential buyers should ensure their pool's specifications match the liner's size and style to avoid any mismatch. Additionally, some users might find the installation temperature guidelines a bit cumbersome, as it requires installation in specific temperature ranges for optimal results. This pool liner is well-suited for those with standard steel-sided above-ground pools looking for a durable and attractive covering solution.
