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)

Frequently Asked Questions
Which pool type is most popular in Florida?
Both fiberglass and gunite are common in Florida. Gunite has historically dominated, but fiberglass is growing rapidly due to lower costs and faster installation. Many of Florida's top pool builders now offer both.
How much does a fiberglass pool cost to install in Florida?
A typical fiberglass pool in Florida (16x32 ft) runs $45,000–$65,000 installed, including excavation, plumbing, equipment, decking, and permits. Gunite of comparable size runs $65,000–$90,000.
Do fiberglass pools crack in Florida's soil?
Fiberglass pools are actually better suited to Florida's shifting sandy soil than gunite. The shell flexes slightly with soil movement rather than cracking. Gunite's rigid structure is more susceptible to cracking from settling.
What pool type adds most value to a Florida home?
Both add significant value — pools increase Florida home values by $20,000–$40,000 on average. Custom gunite pools with higher-end finishes may appraise slightly higher, but fiberglass pools provide better ROI due to lower ongoing costs.
