10 Reasons Why Fiberglass Pools Are Better Than Concrete

The Smarter, Faster, and Stronger Choice for Modern Homeowners

For years, concrete (gunite) pools were the default choice. Today, fiberglass pools have taken the lead — offering faster installation, lower maintenance, and unmatched durability. Rainforest Pools builds every shell in America using advanced composites designed to handle Florida’s heat, humidity, and sandy soils. Here are 10 reasons homeowners are making the switch.


1. Faster Installation

Fiberglass pools install in as little as 2–3 weeks.
Concrete pools often take two to three months to complete. Because Rainforest pools are pre-molded, your installer simply excavates, sets the shell, connects plumbing, and backfills — fast, clean, and ready to enjoy sooner.


2. Lower Lifetime Cost

No resurfacing. No liners. No hidden costs.
Concrete pools require acid washing, tile replacement, and resurfacing every 10–15 years. Fiberglass pools keep their glossy finish for decades, saving thousands in upkeep.


3. Minimal Maintenance

The smooth surface prevents algae and staining.
Concrete’s porous texture breeds algae, demanding weekly scrubbing and heavy chemical use. Fiberglass stays smooth, reducing chemical costs and cleaning time by up to 40%.


4. Cooler, More Comfortable Surface

Fiberglass stays cooler under the Florida sun.
The gelcoat surface reflects heat, keeping water and deck temperatures comfortable — even in mid-summer. Concrete can reach surface temps 10–15°F hotter.


5. Non-Porous & Chemical Efficient

Fiberglass uses fewer chemicals and less chlorine.
Because the shell is non-porous, pH stays stable longer. Homeowners enjoy crystal-clear water without constant balancing.


6. Engineered for Stability

Built to flex — not crack.
Concrete pools are rigid and can crack under soil movement or settling. Fiberglass shells are engineered to flex slightly, ideal for Florida’s sandy soils and high water table.


7. Beautiful Designs & Built-In Features

Choose from modern shapes, tanning ledges, and spas.
Each Rainforest model comes ready with molded steps, benches, and seating areas. Concrete pools require these to be built and finished separately — adding cost and time.


8. Perfect for Saltwater Systems

No corrosion or rough surfaces.
Salt systems are common in Florida, and fiberglass is the best match. The smooth, inert surface resists salt damage and keeps the finish beautiful for decades.


9. Lifetime Structural Warranty

Peace of mind that concrete can’t match.
Rainforest Pools backs every shell with a lifetime structural warranty — something few concrete builders can offer. Your investment is protected from day one.


10. Long-Term Value & Resale Appeal

Adds beauty and reliability to your property.
Homebuyers love low-maintenance fiberglass pools. They know the upkeep is minimal and the look lasts — making your home stand out in the Florida market.


The Bottom Line

Concrete had its time. Fiberglass has perfected the process — stronger materials, faster installation, and less maintenance for life.
When you choose Rainforest Pools, you’re investing in a pool that performs beautifully in Florida’s climate and adds value for decades.
