A swimming pool made of fiberglass will be sold as a large one-piece shell that arrives at your home by truck and then is positioned in the excavated hole with the help of a crane.

Fiberglass pools are ready-made, with typically 30+ designs available, making it rare to request a customized design. Most fiberglass manufacturers offer many models and sizes to choose from. Steps, spas, and benches are usually built into the form.

Fiberglass makes the pool-building process quick and easy. Its smooth interior surface is slick, making it tough for algae to cling to.
