SmartLine Stone Harbor 18×33 Oval Liner — 52″ Wall
The 18′ x 33′ oval liner with a 52-inch wall height uses a Unibead style for steel-sided above-ground pools. The Stone Harbor pattern features a tiled-blue bottom that transitions to marble-like tiles, delivering a classic, evergreen look suitable for stone-surround settings. The liner is hand-folded to minimize creasing and wrinkling, with installation guidance recommending warm temperatures (70–80°F) for best stretch. This option includes a gasket kit and is designed to fit flat-bottom ovals with a 52″ wall.
Considerations: Ensure proper measurement by assessing the outside wall height from ground to top rail, and confirm the pool is compatible with a 52″ wall and Unibead/Bead receiver installation. The pattern balances aesthetic appeal with durability and cost efficiency for semi-inground installations with stone surrounds.
SmartLine Stone Harbor 15×30 Oval Liner — 48″ Wall
This 15′ x 30′ oval liner uses Unibead style for steel-sided above-ground pools with a 48″ wall. The Stone Harbor pattern presents a blue mosaic bottom transitioning to marble-like tiles, offering a timeless accent for stone-surrounded pools. It’s designed for durability and affordability, with guidance to pre-warm the vinyl in sun to improve stretch during installation. The kit includes a gasket, ensuring a tight seal in standard bead or j-hook adapters as applicable.
Key notes: Verify pool dimensions and ensure compatibility with oval shapes measuring across the center for the longest and widest ends. This size is well-suited for mid-sized semi-inground setups paired with stone accents.
SmartLine Stone Harbor 18×33 Oval Liner — 52″ Wall (20 Gauge)
This version mirrors the 18×33 oval shape with a 52″ wall and uses a heavier 20 gauge vinyl. The pattern mirrors the blue mosaic-to-marble design for a stone surround aesthetic. It features a hand-folded North American cut material to minimize creases and suggests installation in warmer conditions for best vinyl stretch. It retains the Unibead style compatibility for steel-sided pools and includes a gasket kit for secure sealing.
Considerations: The 20-gauge vinyl offers extra durability for semi-inground environments that experience UV exposure and temperature shifts. Confirm that the pool’s beaded or j-hook configuration matches the liner’s installation method.
SmartLine Stone Harbor 15×30 Oval Liner — 48″ Wall (24 Gauge)
This 15′ x 30′ oval liner is designed for 48″ walls with a 25 gauge equivalent, offering robust wear resistance for semi-inground pools with stone surrounds. The Stone Harbor pattern provides a blue mosaic transitioning to marble-like tiles, and like other liners, it requires sun warming before stretching for easier installation. It’s suitable for unibead or bead-receiver setups on steel-sided pools, with a gasket kit included for secure sealing.
Key considerations: Check pool wall height and ensure the liner size matches the interior dimensions, particularly for oval shapes where measurement is taken across the center from longest to widest ends. This gauge level is a balance between durability and cost for long-lasting stone-surround aesthetics.
SmartLine Stone Harbor 15×24 Oval Liner — 48″ Wall (25 Gauge)
This 15′ x 24′ oval liner fits 48″ wall pools and uses a 25 gauge vinyl for added durability in semi-inground installations. The Stone Harbor motif remains consistent, offering blue mosaic floors and marble-like tiles that complement stone-surround themes. The liner is designed for quick installation with either unibead or standard bead systems, and it includes a gasket kit for a tight seal. Pre-warm the vinyl to enhance stretching before water fill to minimize wrinkles.
Purchase considerations: Measure the pool accurately, ensuring the interior dimensions align with a 48″ wall oval. The lighter 15′ x 24′ size is ideal for tighter layouts within stone-surrounded backyard designs while still delivering a classic look.
Buying Guide: Key Purchase Considerations for Stone-Surround Semi-Inground Pools
- Pool shape and size compatibility: Oval versus round shapes require different measurement approaches. Always measure from the center to determine longest and widest spans for oval pools, and measure wall height from ground to top rail.
- Vinyl gauge and durability: 25 gauge (and thicker) liners offer greater wear resistance in sunny, outdoor environments. If your setup faces more frequent temperature changes, a heavier gauge can extend liner life.
- Bead configuration: Unibead liners work with flat-bottom pools and require compatible bead receivers. Confirm if your pool uses beaded, overlap (J-hook), or unibead systems before purchase.
- Pattern and aesthetics: Stone Harbor’s blue mosaic-to-marble pattern aligns well with natural stone surrounds, enhancing visual harmony with stone coping. Consider how the liner’s look complements your actual stone features.
- Installation guidance: Pre-warm vinyl in sun for 60–120 minutes to improve stretch. Install within optimal temperature ranges (roughly 70–80°F) to minimize wrinkles and ensure proper fit.
- Gasket and seals: Ensure the kit includes a gasket set for secure water-tight seals, particularly for semi-inground installations that may experience ground movement or soil shifts.
- Maintenance and longevity: Heavier gauges and quality vinyl resist algae and UV exposure better, reducing maintenance in sun-drenched climates typical of many American backyards.
- Warranty and support: Check manufacturer warranties and availability of customer support for installation questions or replacement parts, especially for stone-surround pool environments where alignment matters.
