Swimline li1833bso Pool Liner 18x33 Oval Overlap 48/52 in

Product Description

The SWIMLINE li1833bso is a vinyl above ground pool liner designed for oval pools measuring 18 feet by 33 feet with a 48/52-inch wall height. It uses an overlap bead type, meaning the liner drapes over the top of the pool wall and is secured with coping strips rather than snapping into a track. The Boulder Swirl pattern gives the pool interior a textured stone appearance. This is a direct replacement liner for oval above ground pools and is typically installed by pool service professionals or experienced DIYers during seasonal opening or liner replacement service calls.

This liner is suited for residential above ground oval pool installations where the existing pool frame accommodates an 18-foot by 33-foot footprint and a wall height of 48 or 52 inches. The overlap bead style is one of the most common liner attachment methods found on above ground pool walls, making this a widely applicable replacement option for that pool size and shape. No specific brand model compatibility was stated in the product data, so verify your pool frame dimensions and bead track type before ordering.

Compatibility

Designed as an OEM-style replacement liner for oval above ground pools with an 18-foot by 33-foot pool size, a wall height of 48 or 52 inches, and an overlap-style bead attachment. Confirm pool frame dimensions and bead type before installation.

Installation Notes

Above ground pool liner replacement is typically performed by pool service technicians or qualified installers. Before beginning, drain the pool completely and disconnect any return fittings, skimmer faceplates, and main drain covers. Warm temperatures above 70 degrees F make the vinyl more pliable and easier to set without wrinkles. Follow local pool installation codes and manufacturer guidelines for coping strip installation to ensure the overlap bead seats evenly around the full perimeter of the wall.
