Swimline Unibead Portofino Pool Liner

The Unibead design is a dual-function feature that gives you flexibility during installation. It allows the liner to be installed either as a standard J-hook bead or as an overlap style, making it compatible with different pool wall configurations.

Yes, this liner is constructed from 25-mil virgin vinyl. This thickness provides a robust barrier against everyday wear and tear, and the double-welded seams add extra reinforcement to prevent splitting at the most vulnerable points.

The material is specifically engineered to be UV-resistant, which helps protect the pattern from premature fading caused by direct sunlight. While all pool liners will eventually show some wear, this construction is designed to maintain its appearance through harsh seasonal changes.

While the liner is chemically resistant, you should still maintain proper water chemistry balance to extend its lifespan. Avoid using harsh, abrasive cleaners and ensure your pH and chlorine levels stay within the recommended range to prevent long-term degradation of the vinyl.

This liner is specifically sized for a 48-inch deep, 24-foot round pool. Using it in a pool with a different depth will likely result in an improper fit, causing the liner to stretch, wrinkle, or pull away from the wall, which can lead to premature failure.
