Smartline River Slate 33 Ft Round Liner
The 33 ft River Slate round liner is designed for steel-sided above-ground pools with a 54-inch wall. This overlap liner requires coping strips to secure the bottom seam and is compatible with flat bottoms. The River Slate pattern provides a modern, natural stone appearance, and the liner is hand-folded to minimize creasing. Before installation, warm the vinyl in the sun for 60-90 minutes to aid stretch during water filling. Measure your pool height and diameter to confirm fit.
Key considerations: overlap installation means no bead receivers are needed, and the liner works best with a compatible 54″ wall and flat-bottom design. For long-term color retention, ensure proper pool chemical balance and limit direct sun exposure when not in use.
Smartline River Slate 27 Ft Round Liner
This 27-foot round liner offers River Slate durability with a 54-inch wall height, designed for steel-sided above-ground pools. The liner’s North American cut and hand-folded construction help prevent creasing and wrinkles. For best results, lay the liner in the sun for about an hour to warm the vinyl before filling, ideally at temperatures around 70–80 degrees Fahrenheit. Measure carefully—round pool diameter is wall-to-wall distance, and height is from ground to beneath the top rail.
Pros include a budget-friendly option that still delivers a premium look, and a simple overlap installation that avoids bead receivers. The pattern provides a shimmering, cool appearance reminiscent of natural slate—great for a contemporary backyard vibe.
Smartline River Slate 21 Ft Round Liner
The 21-foot River Slate round liner is another option in the same pattern family, with a 54-inch wall height and 25-gauge virgin vinyl. The liner is designed for steel-sided above-ground pools and uses an overlap method, secured with coping strips. The River Slate aesthetic is described as shimmering and modern, echoing natural slate tones. To optimize fit, warm the vinyl in the sun for at least an hour before installation and verify measurements: pool height and diameter must align with the liner size.
Considerations: ensure your pool has a flat bottom and a compatible wall height. The overlap style requires proper wall-to-wall measurement and cove alignment; improper sizing can affect bottom seam alignment near the cove area during water fill.
Smartline 12 Ft x 18 Ft Oval River Slate Liner
This oval liner accommodates pools with an outside-to-inside measurement and a 48-52 inch wall height. The 12×18 layout is ideal for oval pools and uses a River Slate pattern that mimics natural stone for a sophisticated look. As with other overlap liners, warm the vinyl before installation and drape it over the walls for even bottom seam alignment near the cove. The liner is compatible with flat-bottom pools and requires coping strips for secure installation.
Benefits include a distinctive oval footprint option with the same durable 25-gauge Virgin Vinyl, providing consistent color and pattern across different pool shapes. Users should double-check pool measurements to avoid mismatch and ensure long-term performance.

Buying Guide: Key Considerations For Blue Slate Pool Liners
When selecting a blue slate-inspired liner, consider pool shape, wall height, and installation method. River Slate patterns offer a contemporary stone-like appearance, suitable for various pool sizes and shapes, particularly round and oval configurations common in American backyards.
Fit and sizing are critical. Overlap liners are generally easier to install for flat-bottom pools with fixed wall heights, but you must measure height (ground to under the top rail) and diameter (center wall to wall) accurately. Round pools require diameter measurements, while oval pools require both length and width measurements. Always warm vinyl in sun before installation to improve stretch and reduce creasing.
Durability and gauge impact longevity. A higher gauge (e.g., 25 gauge) offers more abrasion resistance than a 20 gauge option, though both can perform well with proper maintenance. Confirm compatibility with your pool’s wall height and bottom design; some liners are not suitable for Intex or Pop-Up pool variants.
Installation method matters. Overlap liners drape over the walls and are secured with coping strips. Bead receivers are not needed for overlap designs, but exact alignment of the bottom seam near the cove is essential to prevent wrinkles after water fill. For color longevity, protect liners from excessive sun when possible and manage chemical balance to preserve the slate-like pattern over time.
Repair and maintenance. Keep a vinyl repair kit on hand for punctures or tears. Quick, proper repairs extend the life of a blue slate liner and help preserve the aesthetic. Regular cleaning with non-abrasive cleaners prevents surface dulling or staining, maintaining the liner’s natural slate appearance.
