Three Ways to Build a Pool, No Perfect Answer
Every inground pool in Orlando is built one of three ways: sprayed concrete (gunite), a factory-made fiberglass shell, or steel walls with a vinyl liner. Ask around and everyone has a favorite — usually whichever one they sell. Here's the honest version: each type is the best choice for a different kind of homeowner. The trick is matching the pool to your budget, your timeline, your yard, and how much maintenance you're willing to do.
Gunite Pools: The Custom Option
Gunite is concrete sprayed at high pressure over a steel rebar frame, built entirely in your backyard. It's the most labor-intensive method and the most expensive — roughly $60,000–$125,000+ in Orlando — and construction typically takes 8–14 weeks after permits. Every project differs — the written quote is the real number.
What you get for that money is freedom. Any shape, any size, any depth. Tanning ledges, beach entries, attached spas, waterfalls, grottos, vanishing edges — if you can sketch it, a good crew can build it. The interior is plaster, quartz, or pebble aggregate. The downside: the surface is porous and rough compared to the other types, so algae gets a better foothold and brushing matters more. Plan on resurfacing every 10–15 years, which is a five-figure job. Gunite suits you if you want a fully custom design, have the budget for it, and don't mind a longer build or more hands-on maintenance.
Fiberglass Pools: The Fast, Low-Fuss Option
A fiberglass pool is a single finished shell built in a factory, trucked to your house, and set into a dug hole with a crane. Construction usually takes 3–6 weeks after permits — the fastest of the three by a wide margin. Orlando pricing typically lands around $45,000–$90,000. Every project differs — the written quote is the real number.
The shell's gel-coat surface is smooth and non-porous, which means algae has a hard time gripping it and you use fewer chemicals than a gunite pool. Fiberglass also flexes slightly, so it handles Florida's shifting sandy soil well. The trade-offs: you're choosing from the manufacturer's molds, so no fully custom shapes, and the biggest shells top out around 40 feet. You also need crane access to your backyard — a narrow lot with no way in for a crane rules fiberglass out. Fiberglass suits you if you want the fastest install, the easiest weekly maintenance, and you're happy picking a proven shape.
Vinyl Liner Pools: The Budget-Friendly Option
Vinyl liner pools use steel or polymer wall panels with a custom-fit vinyl liner stretched over them as the watertight surface. They're typically the cheapest to build — roughly $35,000–$65,000 in Orlando — and construction runs about 6–10 weeks. Every project differs — the written quote is the real number.
The smooth liner feels soft underfoot and resists algae reasonably well. But the liner is the catch: Florida's intense sun and heat break it down, and you'll replace it every 7–12 years at a cost of several thousand dollars each time. Liners can also tear or fade, and you can't use a beach entry or tanning ledge the way you can with gunite. Vinyl suits you if upfront budget is the deciding factor and you're comfortable with a known replacement cost down the road. If you're comparing budgets, our Orlando pool cost guide breaks down what each type really costs over time.
Side-by-Side Comparison
Upfront cost: Vinyl is lowest, fiberglass is in the middle, gunite is highest.
Construction timeline: Fiberglass is fastest (3–6 weeks), vinyl is next (6–10 weeks), gunite takes longest (8–14 weeks).
Lifespan of the shell: All three last decades. The difference is the surface: gunite needs replastering every 10–15 years, vinyl needs a new liner every 7–12 years, and fiberglass gel coat typically lasts 20–25+ years before needing refinishing.
Weekly maintenance: Fiberglass is easiest (smooth surface, fewer chemicals). Vinyl is next. Gunite needs the most brushing and chemical attention because of its porous surface.
Customization: Gunite is unlimited. Vinyl offers good shape flexibility within panel systems. Fiberglass is limited to factory molds.
Repairs: Gunite cracks can be patched and replastered; fiberglass repairs are specialized but durable; vinyl liner replacement is straightforward but recurring.
Thinking in 20-Year Cost, Not Just Day-One Cost
The sticker price isn't the whole story. Over 20 years, each pool type has a different maintenance bill. A vinyl pool's lower upfront cost comes with liner replacements every 7–12 years — two or even three replacements over two decades, each several thousand dollars. A gunite pool needs replastering roughly every 10–15 years, a five-figure job each time, plus slightly higher chemical and energy use from its rougher surface. Fiberglass has the lightest long-term surface bill: the gel coat typically lasts 20–25+ years before refinishing, and the smooth surface uses fewer chemicals year after year.
None of this makes one type "cheaper" universally — a basic vinyl pool with two liner replacements can still cost less over 20 years than a loaded gunite pool with a spa, waterfall, and automation. But when you're comparing quotes, ask each builder: what will I spend on this pool in years 5, 10, and 15? The honest ones will tell you. And whatever type you choose, the weekly upkeep routine in our new owner maintenance guide is what actually determines how long surfaces last.
Which One Fits Your Situation?
Choose gunite if: you want a custom shape or luxury features (spa, waterfall, beach entry), you have the budget, and you're fine with a longer build and more maintenance.
Choose fiberglass if: you want to swim as soon as possible, you'd rather spend weekends in the pool than cleaning it, and a factory shape works for your yard.
Choose vinyl if: getting a pool now matters more than having the fanciest pool, and you've budgeted for liner replacements down the road.
There's no wrong answer — only a wrong match. A family that wants a simple rectangle for the kids to splash in doesn't need a $110,000 gunite showpiece, and a homeowner dreaming of a resort-style backyard with a spa and waterfall will be disappointed by a basic shell.
