Smartline 12 ft x 20 ft Oval Pool Liner Solid Blue - Durable Fit

Our review of the Smartline 12 ft x 20 ft Oval Swimming Pool Liner finds it best for owners of steel sided above ground pools who want a straightforward, long-lasting replacement without premium cost. The single biggest reason to buy is its practical combination of 25 gauge virgin vinyl construction and Lamiclear surface technology, which provide abrasion, chemical and UV resistance while remaining simple to install as an overlap liner. Installers should still measure carefully and warm the liner before fitting to avoid creases.

Key Features

• Durable construction: The 25 gauge 100% virgin vinyl base resists chemicals and wear so the liner holds up through regular pool use.
• Lamiclear finish: The acrylic top coat and UV resistant print layer help reduce fading and surface damage over time.
• Overlap installation: Drapes over 48-52 in walls and secures with coping strips, making it compatible with many steel framed above ground pools.
• Hand-folded material: North American cut panels are folded by hand to limit permanent creasing and excess wrinkling during storage and shipping.
• Easy prep: Laying the liner in sun for at least an hour warms the vinyl so it stretches more easily during fill and reduces installation stress.
• 25 year limited warranty: Coverage against defects in material and workmanship adds assurance for long term use.

Who It's For

This liner is ideal for homeowners with steel sided above ground oval pools sized approximately 12 ft x 20 ft and wall heights of 48 in or 52 in who want a reliable, budget-friendly replacement. It suits DIY installers comfortable measuring pool dimensions and using overlap coping strips rather than bead receivers.

It is not intended for Intex or pop-up style pools, or for buyers who need a custom-beaded liner or a thicker commercial-grade option. Those wanting flawless colorfastness or a zero-wrinkle guarantee over many years should weigh that need against its value orientation.

Pros & Cons

Pros

• Looks good in the pool with a solid blue print that gives a cool, shimmering appearance.

• Durable material and Lamiclear layers resist abrasion, chemicals and UV compared with untreated vinyl.

Cons

• Some users report noticeable fading and wrinkles over time, so expect aesthetic aging in sunny, high-use installations.
• Not compatible with Intex or pop-up pools and requires flat bottom pools for proper fit.
