Smartline 27 ft Round Swimming Pool Liner Stone Harbor - Unibead Style

Our review of the Smartline 27 ft Round Swimming Pool Liner finds it best for homeowners replacing or upgrading a standard steel sided above ground pool who want a classic, low-cost look with reliable fit. The standout reason to buy is its Stone Harbor tiled marble pattern that gives a clean, attractive pool floor while the unibead design and hand-folded North American cut vinyl make installation straightforward and reduce permanent creases. For those wanting a durable, well-fitting liner with an included gasket kit, this liner delivers sensible value.

Key Features

• Pattern and finish: The tiled blue and marble geometric bottom creates an attractive, classic look that improves the pool aesthetic without being overly bold.
• Material handling: North American cut vinyl is hand-folded to prevent permanent creasing and minimize excess wrinkling during installation and use.
• Installation guidance: Liner should be warmed in the sun for at least one hour and installed when temperatures are ideally 70-80 degrees to ensure proper stretch and fit.
• Unibead versatility: The unibead style works with flat-bottom pools with 52 in wall height and adapts for overlap or beaded installations by removing the j-hook portion as needed.
• Included gasket set: A universal gasket kit for skimmer and return is included to help prevent wall corrosion and reduce leak risk after liner replacement.

Who It's For

This liner suits owners of 27 ft round, steel sided above ground pools with a 52 in wall height who want a straightforward replacement that balances appearance and cost. It is ideal for people who prefer a classic tiled blue floor and who can install at moderate temperatures or have help to warm and stretch the vinyl before filling.

It is not for owners of pop-up style pools, nonsteel walls, or those needing custom sizes or thicker commercial-grade vinyl; buyers requiring a different wall height or a pop-up compatible liner should look elsewhere.
