Fiberglass pools can be installed much quicker that other types of pools because they are preformed in a factory setting. The fiberglass pool is then shipped to your location and put into place with a crane. They are non-porous which lends to them using less chemicals that other pools. Due to the fact that fiberglass pools are shipped to your site there are limitations on size and the variety of shapes available. Typically, fiberglass pools are no wider than 16′ due to the difficulty involved with shipping from the factory to your property.
