Custom Rectangular Replacement Pool Liners – Made in Canada by 7-11 Pools

Our custom rectangular replacement pool liners are proudly manufactured in Canada by 7-11 Pools, a family-owned and operated company with over three generations of experience in pool liner manufacturing. Built to exacting standards, these liners are produced to Standard Specification, meaning they are designed to fit the true pool dimensions stated when measured correctly.

To ensure a perfect fit, professional liner measurement services are available, taking the guesswork out of ordering and helping prevent costly installation errors.
Pro Tip: Always measure wall-to-wall length, width, and wall height for the most accurate liner fit.

Premium Liner Construction & Performance

Each liner is crafted from 30 mil thick, 100% virgin vinyl, delivering superior durability, flexibility, and long-term performance. Using the most advanced radio frequency (R.F.) vinyl welding technology, seams are lap-welded to minimize cold spots and reduce the risk of seam separation. Every liner is individually inspected during the welding process by quality control specialists to ensure consistent craftsmanship.

Designed for Canadian climates, these liners feature UV inhibitors, bacteria resistance, and cold-crack protection, allowing them to withstand harsh sun exposure, pool chemicals, and winter temperatures down to -20°C.

Installation Recommendations & Pro Tips

For the best possible fit, appearance, and liner longevity, please follow these installation best practices:

• Do not install or fill the liner at night. Proper lighting and warmer temperatures allow the vinyl to stretch evenly and settle correctly.

• Install at 18°C (65°F) or warmer for optimal flexibility. Warmer vinyl reduces wrinkles and minimizes stress on seams during filling.

• Professionally measured liners are guaranteed to fit when measurement services are used, eliminating guesswork and costly mistakes.

• Fill the pool slowly using a standard garden hose. Avoid using fire hoses or high-volume water sources, as rapid filling can place unnecessary stress on seams.

• Use commercial shop vacuums (1–2 units, more for larger pools) during installation to pull the liner tight against the walls and floor before filling. This significantly reduces wrinkles and seam stress.

• Ensure the liner is properly centered and seated before water reaches 1–2 inches deep.

Pro Tip

Taking extra time during installation dramatically extends liner life. Proper temperature, controlled filling, and vacuum-assisted seating help prevent wrinkles, seam separation, and premature wear.
