Product details

This is the Swimline LI1848BSO25, a heavy gauge overlap liner in the Boulder Swirl pattern, sized for an 18 ft round above ground pool with a 48 in. or 52 in. wall.

Overlap fitting

An overlap liner is hung by folding it over the top of the pool wall and locking it down with coping strips. There is no bead to snap into a track, which makes it the simplest of the above ground liner styles to fit and the usual choice on older round pools.

Heavy gauge

Swimline lists this one as heavy gauge, in its Perma 25 line. The thicker material is the reason to pay up on a liner: it takes handling during installation and the daily wear at the water line better than the standard gauge version of the same pattern.

Measure the pool and confirm the wall height before ordering, since an overlap liner has to reach over the wall with enough material left to hold.

Questions and answers

What people ask about this product, answered by our pool techs.

Will it fit a 48 in. wall or a 52 in. wall?
Both. This liner is listed for 48 in. and 52 in. wall heights on an 18 ft round pool.
What is an overlap liner?
The liner is pulled up and folded over the top of the pool wall, then held in place with coping strips. It does not need the bead track that unibead and beaded liners use.
What does heavy gauge mean here?
It is the thicker of the two builds Swimline offers in this pattern. Swimline lists this one as Perma 25.
Is the Boulder Swirl pattern on the wall or the floor?
This liner is listed simply as Boulder Swirl, without separate wall and floor patterns called out.
