10 Best Above Ground Pool Liners 2026 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.

The Smartline Waves of Poseidon 24-Foot Round Liner is designed for steel-sided above-ground pools with a 48-to-52-inch wall height. Made from 25-gauge vinyl, this liner is durable without being overly expensive. Its overlap style makes installation straightforward, requiring only coping strips to secure it. The beautiful Waves of Poseidon pattern features interchanging navy and sky blues, which can add a pleasing aesthetic to your pool.

It is essential to measure your pool accurately before purchasing to ensure it fits correctly. The liner needs to be laid out in the sun before installation to prevent creasing and ensure it stretches properly when filling the pool with water. It is not compatible with Intex or pop-up pools, and it must be installed at temperatures between 70-80 degrees for optimal results. The included universal gasket kit is a helpful addition, preventing corrosion and potential leaks.

The liner's weight of 71.2 pounds may be cumbersome for some users.

The Smartline Boulder Swirl 24-Foot Round Liner is a solid choice for those with steel-sided above-ground pools. Made from 25 gauge virgin vinyl, it offers durability and a pleasing blue rock and swirl water pattern. This overlap-style liner is designed to fit pools with a flat bottom and wall heights between 48 to 52 inches, making it versatile but not suitable for Intex or pop-up pools.

The installation is user-friendly, thanks to the drape-over design and the included coping strips, which help secure the liner in place without the need for bead receivers. An added bonus is the universal gasket kit for the skimmer and return, which can help prevent corrosion and leaks over time. The liner’s North American cut material is hand-folded to minimize creasing, and laying it out in the sun before installation can make it easier to work with.

On the downside, the liner is quite heavy, weighing in at 71.6 pounds, which might be challenging for some during installation. The Boulder Swirl liner could be a great addition for families looking to enjoy their backyard pool during hot summer days, provided they ensure accurate measurements before purchase.
