Petruccelli L.T.D of North America says; All three types of pools--concrete, vinyl and fiberglass--are available nationwide. However, some types are more prevalent than others in certain regions. The flexibility of fiberglass and vinyl liners makes them ideal for very cold climates where winter freezing and thawing cycles can damage a rigid concrete structure. Vinyl pools are sold in most areas, yet fiberglass is most popular in the south.
