TL;DR
A fiberglass pool shell is a one-piece swimming pool molded in a factory from layered glass fiber and resin with a smooth gelcoat interior, trucked to the site and craned into a prepared excavation. The smooth surface resists algae and is gentle on feet, installation takes days rather than the weeks of gunite, but shapes are limited to the maker's molds and shipping caps width around 16 feet.
What it means
A fiberglass pool shell is a one-piece swimming pool molded in a factory from layered glass fiber and resin with a smooth gelcoat interior, trucked to the site and craned into a prepared excavation. The smooth surface resists algae and is gentle on feet, installation takes days rather than the weeks of gunite, but shapes are limited to the maker's molds and shipping caps width around 16 feet. Proper backfill — typically clean gravel placed as the shell is filled — is what prevents bulging walls and plumbing stress later.
