There are three ways to build an inground pool in Florida — and a real reason nearly every custom Tampa Bay backyard ends up gunite. Here is the honest comparison.
If you are pricing an inground pool in Tampa Bay, you will hear three words over and over: gunite, fiberglass, and vinyl. They are the three ways to build a pool, and they are genuinely different products — not just price tiers. Here is how each one actually works, and where it fits a Florida backyard.
The three pool types, briefly
- Gunite (concrete): a steel-reinforced shell sprayed on-site and finished in plaster or PebbleTec. Fully custom — any shape, depth, or feature.
- Fiberglass: a pre-molded shell manufactured off-site and lowered into the hole in one piece. Fast, but limited to the shapes and sizes that fit on a truck.
- Vinyl-liner: a frame with a printed vinyl liner stretched over it. The lowest up-front cost, with a liner that needs replacing every several years.
Why gunite wins for custom Florida pools
Almost every high-end Tampa Bay pool is gunite, and it comes down to design freedom and durability. Because the shell is formed on-site, there is no shape, depth, or feature it cannot do — sun shelves, vanishing edges, integrated spas, beach entries, and raised walls are all molded in place.
Gunite also holds up to Florida conditions. Our sandy soil, high water table, and salt air are hard on a pool, and a monolithic, steel-reinforced gunite shell is built to ride them out. It is why LIV backs every gunite shell with a lifetime structural warranty.
A gunite shell is engineered to your exact lot — grade, setbacks, and water table included — which matters a lot on Pinellas and Hillsborough sites.
When fiberglass or vinyl makes sense
Fiberglass can be a reasonable choice for a smaller, simpler pool where speed matters more than customization — the shell drops in quickly. The trade-offs are the fixed shapes, the size cap (it has to ship on a road), and the difficulty of a perfect fit on Florida lots with a high water table, where an empty fiberglass shell can shift.
Vinyl-liner pools are rare in Tampa Bay. They carry the lowest up-front number, but the liner is a wear item — figure on replacing it periodically — and they offer the least design flexibility. For most Florida homeowners building a backyard they intend to keep, the long-term math favors gunite.
The bottom line for Tampa Bay
If you want a small, simple pool fast, fiberglass is worth a look. If you want a pool designed around your exact yard and lifestyle — and built to last the life of your home — gunite is the answer, and it is what we build. The best way to compare is to see your actual backyard in 3D first.
Common questions.
For a custom build, yes — gunite lets you design any shape and feature, holds up to Florida soil and salt air, and adds more long-term home value. Fiberglass can make sense for a small, simple, fast install.
A properly engineered gunite shell lasts the life of the home. The interior finish (plaster/PebbleTec) is resurfaced every 10–20 years, but the structural shell itself is built to endure — LIV warranties it for life.
