A gunite pool is the method behind almost every high end custom pool in Central Florida, and it is the reason the pools that last are shaped nothing like the ones dropped in a mold. Where the water table is high and the soil changes lot to lot, how the shell is built decides whether the pool holds true for decades or starts to move in a few seasons. This guide explains what a gunite pool is, how it is built, what it costs here, and how it compares, so you can price a build knowing what you are actually buying.
What Is a Gunite Pool?
A gunite pool is a custom concrete pool built on site by spraying a sand and cement mix over a steel rebar cage, then finishing it with plaster, tile, or aggregate. The shape is unlimited and the shell is engineered for your soil.
Gunite is the name for that sprayed concrete once it is mixed with water at the nozzle. Because the shell is formed in place over steel, a gunite pool can be any depth, any edge, and any shape a designer draws, which is why infinity edges, sun shelves, and grottos are built this way and not in fiberglass. The strength comes from the steel and the shell thickness, and both are calculated for your grade and water table, not assumed.
How Is a Gunite Pool Built?
A gunite pool is built in stages that each have to be inspected before the next begins. The excavation is dug to the design shape, a steel rebar cage is tied to a calculated schedule, the plumbing and returns are set, and then the gunite is sprayed over the steel to form the shell. After the shell cures, the tile, coping, deck, and interior finish go on, and the pool is filled and started up.
The order matters because the parts you never see decide the pool. The steel schedule and shell thickness resist the ground pushing back, the bond beam ties the top of the shell together, and the hydraulics are plumbed before a single tile is set. Construction standards for this work are published by the Pool and Hot Tub Alliance, and a builder who builds to them is a builder who has passed a lot of inspections. Barrier, drain, and safety requirements are set by the Florida Department of Health swimming pool program, and they are designed into the plan at drawing stage, not corrected at final.
A builder who controls design, engineering, and construction with one team can hold that sequence together. If you are weighing companies, our guide on how to choose a pool builder walks the questions that expose who owns the schedule and who subcontracts it.
What Does a Gunite Pool Cost in Central Florida?
A gunite pool costs more than a fiberglass or vinyl pool because it is engineered and built to order, and the price moves with size, depth, finish, and the features designed into it. A simple gunite shell sits at the low end, and a resort style build with a raised spa, water features, and automation sits well above it. The honest number comes from a design consult that sees your lot, not from a table.
The cost drivers, ranked by how much they move the price:
| What drives the cost | Why it moves the number |
|---|---|
| Size and depth | More shell, more steel, more excavation, more water and chemicals |
| Interior finish | Plaster is the floor, quartz and pebble aggregate cost more and last longer |
| Water and fire features | Sheer descents, spillover spas, and fire bowls each add plumbing and gas |
| Automation and lighting | Smart control and color LED add equipment and wiring |
| Site and access | High water table, poor access, or rock changes excavation and dewatering |

Gunite Pool vs Fiberglass and Vinyl: Which Is Right?
A gunite pool is the right choice when the shape, size, or features matter, while fiberglass suits a fast, simple install and vinyl suits the lowest upfront budget. The trade is flexibility and longevity against speed and price. A gunite shell can be resurfaced and reshaped decades later, where a fiberglass shell is a fixed mold and a vinyl liner is replaced on a cycle.
| What decides it | Gunite | Fiberglass | Vinyl liner |
|---|---|---|---|
| Shape and size | Any shape, any depth | Limited to molds | Rectangular, limited |
| Custom features | Infinity edge, sun shelf, grotto, spa | Few, molded in | Few |
| Lifespan of the structure | Decades, resurfaceable | Long, but fixed | Liner replaced on a cycle |
| Upfront cost | Highest | Middle | Lowest |
| Best for | Custom, high end, resort style | Fast simple installs | Tight budgets |
For a homeowner who wants a one of a kind pool that fits the yard and lasts, gunite is the method that makes it possible. You can see the range in our custom luxury pool projects across the region.
Why Does a Gunite Pool Suit Central Florida’s High Water Table?
A gunite pool suits Central Florida because the shell can be engineered to resist a high water table, which a mold cannot. Across much of the region the groundwater sits close to the surface, and the Florida Department of Environmental Protection groundwater program documents how shallow and variable it is. A gunite shell is designed to hold its shape against that pressure from outside, with the steel schedule and shell thickness set for the water and soil at your address.
The soil changes lot to lot, from sand to clay to fill, so a pool poured to one standard is building for an average that does not exist here. A gunite build calculates the structure for what is actually under your yard, which is the part you never see once the pool is finished and the part that decides whether the surface stays true. Building here also means managing groundwater during the dig itself, so a builder who has worked Central Florida lots plans dewatering before the excavation starts, not after the hole fills.
What Finishes Can a Gunite Pool Have?
A gunite pool can be finished in plaster, quartz, or pebble aggregate inside, and tile, stone, or pavers around it, and the finish you pick sets both the look and how often the surface is renewed. Plaster is the standard interior, smooth and the least expensive, and it is resurfaced sooner than the harder finishes. Quartz adds a tougher, more colorfast surface, and pebble aggregate is the most durable and the most textured, reading as a natural bottom rather than a painted one.
The finish also decides the color of the water. A darker aggregate reads deep and reflective, a white plaster reads bright and tropical, and a mid tone sits between them. Because a gunite shell is built to order, the waterline tile, the coping, and the deck are all chosen to match, which is how a custom pool reads as one designed piece rather than a kit. This is the layer a buyer sees, but it sits on top of the engineering that decides whether the pool lasts.
How Long Does a Gunite Pool Last?
A gunite pool lasts for decades because the concrete shell is permanent and the interior finish is renewed on its own schedule. The structure does not expire the way a liner does. The plaster or aggregate surface is resurfaced roughly every ten to fifteen years depending on the finish and the water chemistry, and the tile and coping outlast several resurfaces.
That long life is why gunite is the standard for custom work. Southern Pool Designs has designed and built gunite pools across Central Florida since 1997, more than one hundred million dollars of work, a Top 50 Builder in 2026, an FSPA 2025 Design Award, and a 5.0 rating, and that history is the reason the engineering is settled before the first excavation.
Frequently Asked Questions
Is a Gunite Pool the Same as a Concrete Pool?
Yes. Gunite is a type of concrete pool. The word gunite describes the sand and cement mix sprayed over steel to form the shell. Shotcrete is the same idea with the water added earlier in the hose. Both build a solid, custom concrete shell, and both are what people mean by a concrete pool.
How Long Does It Take to Build a Gunite Pool?
A gunite pool usually takes about three to six months from design to swim, depending on permitting, weather, and the features involved. Design and engineering run a few weeks before the build starts, then excavation, steel, gunite, cure, tile, deck, and finish each need their own window and their own inspection before the next stage begins.
Do Gunite Pools Crack?
A properly engineered gunite pool should not crack, because the steel schedule and shell thickness are calculated for the soil and water table. Cracks come from a shell built too thin, too little steel, or ground that was not accounted for. This is why the engineering matters more than the finish, and in house engineering is what to verify.
Is a Gunite Pool Worth the Extra Cost?
For a custom shape, custom features, or a shell that lasts decades and can be resurfaced, a gunite pool is worth the higher upfront cost. For a small, simple, rectangular pool on the tightest budget, fiberglass or vinyl may fit better. The right answer depends on what you want the pool to be.
What Maintenance Does a Gunite Pool Need?
A gunite pool needs regular water balance, weekly cleaning, and a resurface of the interior finish every ten to fifteen years. Balanced water protects the plaster or aggregate and the equipment. Automation and quality equipment reduce the day to day work, but the shell itself is low maintenance because it is a solid, permanent structure.
