Normally pool liners are made of vinyl and come in different patterns

add comfort to swimmers by adding a cushion between them and the pool’s
concrete walls. The liner’s thickness can determine durability
and cost—the thicker the longer it will last.

The pool liners differ in their installation methods. Beaded liners
can only be used with a bead-receiving track, which either comes with
the pool or can be added with a conversion kit. For overlap liners a
liner clip must be available. The J-Hook liner is shaped like an upside
down j and hooks over the edge of a pool.
