Product details

This is the Swimline LI1854BSU25, an above ground pool liner for an 18 foot round pool with a 54 inch wall. The pattern is Boulder Swirl and the liner is listed as heavy gauge, Perma 25, with a unibead top.

Getting the fit right

Three things decide whether a liner fits: the pool size, the wall height and the bead type. This one is 18 ft round, 54 inch wall, unibead. All three have to match the pool in your yard, and the bead is the one people most often get wrong, so check how the existing liner hangs at the top of the wall before ordering.

Gauge

Heavy gauge liners carry more material than the standard grade, which is the difference that shows up in how they handle sun, chemicals and the knocks of a full season.
