Fiberglass pools are pre-molded shells installed in one piece, making installation faster and more streamlined. Concrete pools are highly customizable and are built on-site, which makes them adaptable in shape but requires a longer installation time. Liner pools, or vinyl liner pools, are constructed with a flexible liner that fits into a pre-built structure, but liners need replacement every 5–10 years. Fiberglass pools strike a balance with durability, minimal maintenance, and a smooth surface that resists algae growth.

Fiberglass pools can often be installed within 1–3 weeks, depending on site preparation and weather. In contrast, concrete pools usually take 3–6 months due to the more extensive construction process. Liner pools take roughly 2–4 weeks to install. Fiberglass pools offer a quick turnaround, so you can start swimming sooner.

Fiberglass pools generally require less maintenance than concrete or liner pools. The smooth, non-porous surface of fiberglass resists algae and requires fewer chemicals, saving on cleaning time and costs. Concrete pools are porous, so they can harbor algae and bacteria, requiring more frequent brushing and chemical treatments. Vinyl liners can be more susceptible to tears and require periodic replacement, which adds to maintenance needs.

Fiberglass pools are built to last, with lifespans of 25+ years or even a lifetime with proper care. Concrete pools also have long lifespans but may need resurfacing every 10–15 years. Liner pools have the shortest lifespan, as the vinyl liner generally needs replacement every 5–10 years.

Fiberglass pools come in a range of shapes, sizes, and designs, though they’re typically less customizable than concrete pools, which can be designed to fit any space. However, with advances in manufacturing, many fiberglass models feature popular, versatile designs that suit most spaces and styles.

Fiberglass pools are highly durable due to their flexible and resilient construction. They’re resistant to cracks caused by ground movement, unlike concrete pools, which are prone to cracking and can require costly repairs. Liner pools are more vulnerable to tears and punctures, needing repairs or replacement over time.

Fiberglass pools have a moderate upfront cost, but they are often the most economical in the long run. Due to their durability and low maintenance needs, fiberglass pools can save thousands on chemicals, cleaning, and resurfacing over time. Concrete pools generally have the highest initial cost and require regular upkeep, which adds to long-term expenses. Vinyl liner pools have lower upfront costs but require liner replacements, which can be a recurring expense.

Fiberglass pools are ideal for saltwater because they’re non-corrosive and can withstand the salt without damaging the surface. Concrete pools are vulnerable to salt damage and may require additional treatments to prevent erosion. Vinyl liner pools can also work with saltwater systems, but the liner can wear down faster.

The smooth surface of fiberglass pools feels gentle underfoot and is less prone to algae growth, which contributes to cleaner, softer water. Concrete pools have a rougher texture that can feel abrasive and make cleaning harder. Vinyl liners are smooth but can wrinkle or fade over time, affecting comfort and aesthetics.

Fiberglass pools can add significant resale value due to their low maintenance requirements, durability, and appeal to buyers looking for hassle-free options. Concrete pools can also increase home value but may not be as desirable to buyers due to maintenance needs. Liner pools may add less value since prospective buyers often factor in the cost of liner replacement.
