It features a beautiful blue tiled pattern with marble-like geometric shapes that create a classic look. Made from 25-gauge virgin vinyl, the liner is designed to be strong and long-lasting.

The material is hand-folded to avoid permanent creases and wrinkles, and it is recommended to warm the vinyl in the sun before installation to ensure proper stretching. It is best installed in temperatures between 70-80 degrees. The liner is versatile with its unibead style, making it compatible with both overlap and beaded style pools, although it is not suitable for Intex or Pop-Up pools.

The included universal gasket kit helps prevent corrosion and leaks by fitting both standard and wide-mouth skimmers. It's important to measure your pool correctly to ensure the right fit. Potential users should be cautious of the installation process and compatibility with their specific pool type. The product ranks well in its category, being #26 in pool liners, which reflects its popularity and reliability.

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.

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.

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.
