Fiberglass pools are in-mold, handcrafted pools that arrive at your home ready to be installed in your yard. The fiberglass is created from millions of interwoven glass threads covered with polyester resin. It’s an incredibly sturdy material that’s ideal for an in-ground pool. In comparison, a concrete pool requires a steel or wooden framework that needs to be covered by a mixture of cement, sand, and water. Fiberglass is the material of choice for bathtubs, sinks, hot tubs, and multi-million-dollar yachts, not to mention, airplanes, helicopters, exotic automobiles, and many other high-performance products. As such, fiberglass is the best choice for the material for your inground swimming pool.
