A mid-size fiberglass pool (about 14×30) installed in Hattiesburg typically runs $49,500–$72,500 with standard equipment and a basic concrete deck. The shell itself is usually a third to half of that:
| Job | Typical Hattiesburg price |
|---|---|
| Shell only, delivered (small to large) | $15,500–$38,500 |
| Small shell installed (about 12×24) | $35,500–$51,000 |
| Mid-size shell installed (about 14×30) | $49,500–$72,500 |
| Large shell installed (about 16×40) | $68,000–$98,000+ |
| Built-in tanning ledge or splash pad model | $3,500–$7,500 |
| Attached fiberglass spa | $10,000–$21,500 |
| Decking and coping | $5,000–$13,500 |
| Equipment upgrades (heater, salt, automation) | $3,000–$10,000 |
| Crane or access fees | $1,300–$4,300 |
| Permits and engineering | $400–$2,600 |
Mississippi pricing is below the national baseline used for these estimates. Shell brand and size set the base; crane access, backfill material, decking and the equipment package explain most of the spread between quotes for the same model.
Browse the manufacturer catalogs first — most installers carry one or two brands, and the model you want decides who can bid.

Yazoo clay around Jackson is genuinely expansive — shells there need conservative engineering and great drainage, and a local builder will talk about it unprompted (treat that as a good sign). The coast brings sand and water-table management; hurricane-zone equipment anchoring matters south of I-10. Fiberglass shells arrive finished, so the local work is excavation, setting, plumbing and decking — the ground conditions and the crew's setting method matter more than with any other pool type.

Confirm the dealer is authorized by the shell manufacturer (that keeps the shell warranty valid), ask how the shell is leveled and backfilled, and compare quotes for the same model with the same deck and equipment. Mississippi licenses residential builders at the state level for larger projects — verify the license and insurance before you sign. Pool permitting and barrier/fence rules are handled by city and county offices, and coastal counties add wind and flood-zone considerations your builder should already know cold.
A mid-size fiberglass pool installed in Hattiesburg, MS typically runs $49,500–$72,500; small shells run $35,500–$51,000 and large shells $68,000–$98,000+. The shell itself is $15,500–$38,500 delivered. Decking ($5,000–$13,500), an attached spa ($10,000–$21,500) and equipment upgrades ($3,000–$10,000) are the common extras. Mississippi pricing is below the national baseline used for these estimates.
The structural shell commonly carries a lifetime or 25-to-35-year warranty and the gelcoat surface 10 to 20 years before it may need recoating. Proper backfill and balanced water (especially calcium and pH) are what keep the surface and the structure in shape; cobalt staining and spider cracks are usually water-chemistry or installation issues rather than shell defects.
Once the permit is in hand, most fiberglass installs are swimmable in two to six weeks: a day or two to dig, a day to set and plumb the shell, a few days for the concrete collar and deck, then fill and startup. Shell lead times from the factory can add several weeks in spring. Installers dig as soon as the ground allows and book the spring slots early.
Fiberglass wins on speed, maintenance and long-term surface cost; gunite wins on custom shapes, depth, features and size. Installed prices for a mid-size pool are often similar once a gunite pool's finish and features are included, but a gunite pool will need a resurfacing in 10 to 20 years that a fiberglass pool usually does not. Pick by shape and size first, then compare total cost of ownership.
The outdoor season in Hattiesburg runs April through October — about 7 months unheated, with a heater adding several weeks on each end. Winters are mild enough that many owners idle equipment with a partial close instead of a full winterization. The season stretches April through October, and the Gulf Coast pushes longer. Heat plus humidity means algae never sleeps in summer, afternoon storms are routine, and winters are mild enough that a full northern-style close is optional in the southern half of the state.
Outdoor Living & Design has the highest customer rating on this Hattiesburg list at 4.8 stars across 16 reviews. Adcock Pool Spa & Billards has the largest review count (34 reviews at 4.7 stars).

Nearly anywhere a flatbed and a crane or excavator can reach the yard — tight side yards, overhead power lines and steep lots are the usual obstacles. High groundwater needs a well point or sump during the install, and expansive clay calls for a gravel base and careful backfill. A good installer will walk the access route before quoting.
Shells range from plunge pools around 8×14 to large models around 16×40, with depths of roughly 3½ to 8 feet. Most manufacturers offer rectangles, freeforms, lap pools and models with built-in tanning ledges, benches and spas. Size is limited by what can be shipped on a truck, so very large pools are built in gunite.
