The 30-Second Verdict
Fiberglass pools install faster (3–6 weeks vs. 3–6 months), cost less to maintain, and use fewer chemicals. Gunite pools offer unlimited shapes and sizes and are preferred for custom designs or pools over 40 feet. For most Florida homeowners, fiberglass wins on total cost of ownership.
Head-to-Head Breakdown
Fiberglass Pool
Pros
- Fastest installation: 3–6 weeks vs. 3–6 months for gunite
- Smooth gel coat surface inhibits algae — fewer chemicals needed
- Lower lifetime maintenance cost (saves $1,000–$2,000/year)
- Factory-quality finish that won't crack from soil movement
- Florida's sandy soil suits fiberglass's flexibility well
Cons
- Limited to pre-made shell sizes and shapes
- Maximum length typically 40 feet
- Delivery requires wide access (16+ feet) to backyard
- Gel coat may fade and require resurfacing after 15–20 years
Gunite (Concrete) Pool
Pros
- Unlimited custom shapes, depths, and features
- Can be built in any backyard regardless of access
- Extremely durable — 50+ year lifespan with proper maintenance
- Better for vanishing edge, beach entry, and complex designs
- Can be resurfaced with plaster, pebble, or tile finishes
Cons
- Higher upfront cost: $60,000–$100,000+ vs. $45,000–$75,000 for fiberglass
- 3–6 month construction timeline
- Porous plaster surface promotes algae — more chemicals needed
- Requires replastering every 10–15 years ($10,000–$20,000)
