The installation time of a fiberglass pool depends on several factors, like weather, the builder’s schedule, and how extensive of a project you have. Many people think of their “pool” as the entire backyard where there pool is; however, the pool itself is the fiberglass shell. The time for completion of your entire backyard poolscape will depend on if you have a concrete patio, travertine, or pavers, as well as other items like outdoor kitchens and showers. Weather and scheduling permitting, most fiberglass pools can be installed in 1-3 weeks to a point where the patio can begin.
