10 Best Above Ground Pool Liners 2025 in the United States

The Smartline 24 ft Round Swimming Pool Liner in Boulder Swirl pattern is designed for steel-sided above-ground pools with wall heights of 48 to 52 inches. Made from heavy-duty 30-gauge virgin vinyl with a special Lamiclear coating, it offers good protection against wear, chemicals, and sun fading, which means it should last through many swimming seasons. The stylish pattern with blue rocks adds a pleasant look to your pool area. This liner uses an overlap style that’s relatively easy to install, as it drapes over the pool walls and is secured with coping strips—no need for bead receivers. It fits only round pools with a flat bottom and won’t work with Intex or pop-up pools.

Installation works best when the vinyl is warmed in the sun and the weather is mild (70-80°F), which helps reduce wrinkles and makes fitting smoother. A 30-year limited warranty is included, offering reassurance against manufacturing defects. While the overlap design is straightforward, it may not provide as tight a fit as bead-style liners, and the liner’s thickness, though heavy-duty, is standard for this price range, so it’s important to handle it carefully during setup.

If you have a steel-sided, round above-ground pool and want a durable, attractive liner without complicated installation, this Smartline product presents a solid choice.

Made from 25-gauge virgin vinyl, this liner promises durability, which is essential for withstanding the rigors of frequent use and environmental exposure. The UniBead style offers versatility, supporting both overlap and beaded pool designs, making it adaptable for various setups. 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. Installation is relatively straightforward but requires careful measurement to ensure a proper fit.

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.

The SmartLine 27 ft Round Swimming Pool Liner in Boulder Swirl pattern is designed for steel-sided above-ground pools. It features a durable 25 gauge vinyl material, which is hand-folded to minimize creasing.

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.
