10 Reasons Why Fiberglass Pools Are Better Than Concrete

Costa Beach Cumba spa by Rainforest Pools

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.

Fiberglass: The Superior Choice for Inground Pools


Let’s Get Started

If you’re considering an inground swimming pool, you’ve likely come across three main options: fiberglass, vinyl liner, and concrete (gunite). While each has its place, fiberglass pools have quickly become the preferred choice for homeowners across the Southeast and beyond—and for good reason.

✅ 5. Built-in Features

Rainforest fiberglass pool shells often include tanning ledges, bench seating, swim-up steps, and spas—all part of the mold, no extra construction required.


Maintenance Comparison: Fiberglass vs. Vinyl vs. Concrete

Let’s break down what you’re really in for when it comes to pool upkeep:

Operating Costs for Fiberglass Pools | Rainforest Pools

Fiberglass Poos by Rainforest Pools

When considering an in-ground pool for your backyard, one of the most important factors to consider is the operating costs. While the initial installation cost can be significant, it’s the long-term maintenance and operating costs that can affect your budget for years to come. Among the various types of in-ground pools, fiberglass pools stand out as a cost-effective option, especially when it comes to long-term expenses. In this post, we’ll break down the operating costs associated with fiberglass pools, so you can better understand the financial commitment involved.

1. Energy Costs

One of the main ongoing expenses for any pool is energy consumption. This includes electricity used for pool pumps, heaters, and lighting. Fortunately, fiberglass pools are often more energy-efficient than other types of pools, such as concrete or vinyl, due to their smooth surface. The smooth gel coat of fiberglass pools reduces friction, allowing the pool pump to operate more efficiently. This means lower energy consumption and reduced monthly utility bills.

Tip: Consider installing an energy-efficient pool pump and using a pool cover when the pool is not in use to further reduce energy costs.

2. Water Costs

Fiberglass pools require less water to maintain their water levels compared to concrete or vinyl pools. This is because the surface of fiberglass pools is less porous, which means they are less prone to evaporation. As a result, you’ll need to top up the water in your fiberglass pool less frequently, saving you money on your water bills.

Tip: Installing a pool cover during the off-season can also help minimize evaporation and reduce water usage.

3. Chemicals and Maintenance

Maintaining water quality is crucial for keeping your pool safe and inviting. Fiberglass pools require fewer chemicals to keep the water clean compared to concrete pools, which can absorb chemicals due to their porous surfaces. The smooth surface of fiberglass pools makes it harder for algae to cling to the walls, meaning you’ll spend less on algaecides and cleaning products.

However, you will still need to maintain the pool’s chemical balance, including chlorine, pH levels, and alkalinity. The cost of pool chemicals will vary depending on the size of your pool and your local water conditions.

Tip: Regular cleaning, vacuuming, and balancing of your pool’s chemicals will help prevent costly repairs and maintain water quality.

4. Cleaning and Maintenance Costs

Fiberglass pools generally require less maintenance compared to concrete pools. The smooth surface of fiberglass prevents the buildup of dirt and debris, which means you’ll spend less time scrubbing and more time enjoying your pool. Most fiberglass pool owners find that they only need to clean their pool once a week, reducing both time and costs compared to more labor-intensive pool types.

In addition, fiberglass pools are durable and resistant to cracking and fading, which means you won’t have to deal with resurfacing or expensive repairs as often.

Tip: Invest in a high-quality pool cleaning system to keep your fiberglass pool in top shape, reducing the need for costly manual cleaning.

5. Repairs and Upkeep

Fiberglass pools are known for their durability. Unlike concrete pools, which are prone to cracking and require periodic resurfacing, fiberglass pools are made from strong, flexible materials that can withstand the test of time. This means fewer repairs and lower maintenance costs over the lifespan of the pool.

If any repairs are needed, fiberglass pools are usually cheaper to fix than other types. For example, if your fiberglass pool has a minor crack or chip, it can typically be repaired easily with a patch kit, while concrete pools may require expensive resurfacing.

Tip: Regularly inspect your pool for signs of wear and tear, and address any small issues early on to avoid costly repairs in the future.

Conclusion

In conclusion, fiberglass pools are an excellent choice for homeowners looking to save on long-term operating costs. With lower energy consumption, fewer chemical requirements, and reduced maintenance and repair costs, fiberglass pools offer significant financial benefits over their lifespan. By taking simple steps to maintain your pool, such as using energy-efficient equipment and keeping the water balanced, you can further minimize operating expenses.

Energy Efficiency and Fiberglass Pools: The Smart Choice for Homeowners

Smarter Pools for a Sustainable Future

Modern homeowners want more than beauty — they want efficiency, sustainability, and smart design.
Rainforest fiberglass pools deliver all three. Each pool shell is engineered for thermal performance, chemical stability, and long-term energy savings, making fiberglass the most efficient inground pool option available today.


1. Natural Insulation Saves Energy

Fiberglass shells retain heat longer than concrete or vinyl.
The composite layers act as insulation, helping your pool stay warmer through cool nights and cloudy days. This means heaters run less, and your water temperature stays steady — saving energy and money year-round.


2. Heats Faster, Cools Slower

Less energy, faster results.
Fiberglass pools require less energy to heat up because the material conducts heat efficiently. Once warm, the shell’s insulation keeps that temperature consistent, so pumps and heaters cycle less often. In warm climates like Florida, South Carolina, and Texas, this translates into noticeable utility savings every season.


3. Lower Pump Run Times

Smooth surfaces = better water flow.
The gelcoat finish creates almost no resistance as water moves through your filtration system. Pumps don’t work as hard to circulate water, which reduces electrical usage and extends pump life. Many Rainforest owners report up to 30% lower electricity costs compared to concrete pool owners.


4. Fewer Chemicals, Less Waste

Efficiency isn’t just about power — it’s about performance.
Fiberglass pools are non-porous, so algae can’t take hold. This stability keeps water balanced longer, reducing chlorine and acid use. With less chemical demand, your filtration system stays cleaner and uses less energy overall.


5. Perfect Match for Solar Heating Systems

Fiberglass works seamlessly with renewable energy.
Because of its excellent heat retention, fiberglass maximizes the benefit of solar pool heaters, capturing and maintaining warmth efficiently. Solar integration is easy and cost-effective — ideal for homeowners focused on sustainable energy solutions.


6. Reduced Evaporation and Heat Loss

A smoother design means a more stable surface.
Fiberglass pools hold temperature and minimize evaporation due to their consistent, smooth structure. The less water you lose to evaporation, the less energy you spend reheating or refilling — a win for both the planet and your wallet.


7. Energy-Efficient Equipment Compatibility

Smart systems make fiberglass even smarter.
Rainforest fiberglass pools pair perfectly with variable-speed pumps, LED lighting, and automated filtration systems. These upgrades reduce electricity usage and extend the lifespan of your equipment.


8. Long-Term Environmental Impact

Less maintenance = less environmental footprint.
Because fiberglass pools never need resurfacing or liner replacement, manufacturing and disposal waste are dramatically reduced. Over 20+ years, fiberglass generates far fewer materials and emissions than concrete or vinyl alternatives.


9. Designed for All Climates

Energy savings in heat or cold.
In warm states like Florida and South Carolina, insulation helps retain comfortable swimming temperatures naturally. In cooler climates, the same property reduces heater usage — making fiberglass a smart, energy-saving choice everywhere.


10. The Lifetime Value of Efficiency

Energy efficiency is about more than monthly bills — it’s about lifetime cost.
Fiberglass pools cost less to operate, maintain, and heat over decades. Combined with Rainforest’s lifetime structural warranty, homeowners get unmatched long-term value and sustainability in one package.


The Rainforest Advantage

Every Rainforest fiberglass pool is made in America and designed to balance performance, comfort, and energy efficiency. The result?
A pool that’s better for your home, your family, and your environment.
