Fiberglass vs Gunite Pool: Which Is Better?

Fiberglass and gunite (sprayed concrete) are the two most common premium pool construction methods. Each has clear tradeoffs in cost, install time, design flexibility, surface comfort, and chemistry maintenance.

Cost

Fiberglass: $48,000 to $95,000 turnkey. Gunite: $65,000 to $185,000 turnkey for a residential build. Gunite scales higher because design is unlimited; fiberglass is capped at manufacturer shell sizes.

Install Time

Fiberglass: 1 to 3 weeks (shell drops in pre-built). Gunite: 8 to 14 weeks (excavate, plumb, steel, shoot, finish, tile, deck, fill, balance).

Design Flexibility

Gunite wins decisively. Any shape, any size, any depth, integrated spas, sun shelves, vanishing edges, raised beam walls. Fiberglass is limited to manufacturer shapes (typically 20 to 25 stock models).

Surface Comfort

Fiberglass: smoother, less abrasive, easier on feet and swimsuits. Gunite plaster: rougher but customizable (pebble for grip, polished aggregate for smoothness).

Chemistry + Algae

Fiberglass: gel-coat surface resists algae better; chemistry stays balanced longer. Gunite: plaster is porous and slightly alkaline, requires more attention.

Lifespan

Fiberglass: 25 to 35 years for the shell. Gel coat may need re-coat at 15 to 20 years. Gunite: 30 to 50 years on the structure. Plaster re-coat every 12 to 18 years.

Verdict

Choose fiberglass for fastest install, lowest maintenance, and tighter budget on a stock-shape pool. Choose gunite for custom geometry, integrated wellness, vanishing edges, or any design that needs to flex around your site.

Our HOA went through three quotes before WETYR. The CPO certification, the chemistry logs, the monthly reports — finally a service company that treats commercial accounts like commercial accounts.
