Fiberglass isn’t. - **Predictable price.** The shell is a known cost; there’s less to discover mid-build. ### What it isn’t - **Limited shapes.** You choose from molds. Custom geometry means gunite. - **Size ceiling.** Roughly 16 ft wide — the width a truck can legally haul. - **Access matters.** A shell needs a path to the backyard. Tight lots may need a crane. - **Groundwater is real.** An empty shell over a high water table will float without hydrostatic relief. Step by step ## How we set a shell on a coastal lot 1. 01 ### Site & elevation survey Flood zone, septic setbacks, HOA architectural review, utility locates. 2. 02 ### Permit & plan County building and electrical. State plan review if the pool is public. 3. 03 ### Excavation & dewatering Shoring in sand; wellpoints if groundwater is within reach of the cut. 4. 04 ### Base & set Compacted gravel base, laser-leveled, shell craned or walked in. 5. 05 ### Plumb & backfill Engineered backfill in lifts, filling with water as it rises. 6. 06 ### Equipment & electric Pad elevated to flood spec. Coastal-rated heater and hardware. 7. 07 ### Decking Concrete, paver or travertine. Bonding grid inspected before pour. 8. 08 ### Startup & handoff Water balance, equipment walkthrough, warranty paperwork. ## Not sure fiberglass is right? ### Concrete / gunite pools Any shape, any depth, any feature — if you’ll trade time for freedom.

[Plunge pools](https://www.sunrisepoolsinc.com/plunge-pools?hsLang=en) ### Swim spas Laps and hydrotherapy in a footprint that fits almost anywhere. [Swim spas](https://www.sunrisepoolsinc.com/swim-spas?hsLang=en) Common questions ## Fiberglass pool questions How much does a fiberglass pool cost in coastal NC? Most land between $90,000 and $160,000 turnkey. Shell size, decking area and whether the site needs dewatering account for most of the spread. Dewatering or crane access typically adds $8,000–20,000. Will a fiberglass pool float in a high water table? Not if it’s installed with a hydrostatic relief valve and never drained without a plan. Floating happens when an empty shell meets groundwater pressure — which is why we don’t drain pools here without wellpoints running. How long do fiberglass pools last? The shell carries a structural warranty measured in decades; gelcoat typically looks new for 15–20 years. Coastal sun and salt affect the deck and the equipment long before they affect the shell. Can a fiberglass pool be saltwater? Yes, and it’s the better material for it — salt is harder on plaster and on metal than on gelcoat. We still spec coastal-rated rails and hardware, because salt air does the rest of the work.
