If you’re in the Southeast and reading this, odds are when it comes to swimming pools, you immediately think of concrete or “tradtional” pools. And for many years, there were no alternatives. But times have changed and more and more homeowners are turning to fiberglass as their choice of material for their new pool. Below are just 10 reasons that fiberglass becoming the most popular pool choice.

1. Faster Installation

Fiberglass pools are pre-manufactured and arrive ready to install. That means your backyard can go from dirt to done in as little as 2–4 weeks, compared to 3–6 months for concrete pools. That means more swim time and fewer delays.

2. Lower Lifetime Cost

While upfront prices may be similar, fiberglass pools save you money over time with lower maintenance, chemical, and resurfacing costs. On averge, a concrete pool owner will need to spend $15,000 mininal every day for the upkeep and maintenance of their pool. Compared to fiberglass pool owners who just need to keep their basic chemicals checked, skim the surface and throw in the vacuum on occassion.

3. Smooth, Non-Abrasive Surface

No scrapes or sore feet here! Fiberglass is silky smooth compared to the rough, porous surface of concrete, which can be harsh on skin.

4. Algae-Resistant

Fiberglass’s non-porous shell resists algae growth much better than porous concrete, reducing the need for chemicals and cleaning.

5. Minimal Maintenance

Say goodbye to hours of upkeep. Fiberglass pools require less brushing, fewer chemicals, and no replastering or tile replacement.

6. Stronger and More Flexible

Fiberglass is engineered to flex slightly with ground movement, reducing the risk of cracking—unlike concrete, which is more rigid and prone to structural damage.

7. Built-In Features

Most fiberglass pools come with built-in steps, benches, tanning ledges, and even spa combos—no need to custom-pour expensive extras.

8. Energy Efficient

Fiberglass insulates better than concrete, helping retain heat longer and reducing energy costs if you’re heating your pool.

9. Modern, Stylish Designs

Today’s fiberglass pools come in a wide variety of elegant shapes, colors, and finishes—many with a high-end look that rivals luxury resorts.

10. Less Downtime, More Swim Time

Because there’s no resurfacing or major repairs needed every 10–15 years, you’ll enjoy more uninterrupted seasons in your pool.
