Based on a 2026 survey of independent fiberglass pool builders in the Thursday Pools dealer network, a standard fiberglass pool installation in Mississippi averages $60,000 for a small pool, $70,000 for a medium pool, and $80,000 for a large pool. Your final cost will depend on details like pool size, yard conditions, local permit requirements, and the optional upgrades you choose.
Mississippi’s long swim season makes a backyard pool one of the most-used outdoor investments a homeowner can make. Fiberglass is particularly well-suited to the state’s climate: the smooth, non-porous surface resists algae growth in Mississippi’s warm, humid environment, and the flexible shell handles the ground movement common in areas with clay-heavy or soft soils. Beyond climate, geography shapes installation costs in real ways. In the rolling terrain of Northeast Mississippi, rocky patches can require extra excavation effort. Along the Gulf Coast and in the Delta, looser soils may need reinforcement to keep the shell secure over time. Thoughtful upfront planning, starting with an honest look at your site, is the difference between a project that goes smoothly and one full of surprises.
A local independent Thursday Pools dealer can help you evaluate your yard, understand local requirements, and choose upgrades that fit your budget.

Aspen is a compact, well-designed fiberglass pool that delivers a lot for smaller backyards across Mississippi. At 25 feet in length, it fits comfortably in suburban lots in Jackson, Gulfport, and Tupelo, and still packs in a built-in tanning ledge, wide entry steps, an open swim lane, and generous bench seating. For homeowners who want a capable pool without the footprint of a larger model, Aspen is a strong starting point.
Based on 2026 feedback from Thursday Pools dealers throughout Mississippi, the average installed cost for a small fiberglass pool like Aspen or other designs less than 26 feet long and 400 square feet is $60,000.

Sun Day brings relaxed, freeform elegance to mid-size backyards across Mississippi. Its organic shape creates a resort-style atmosphere that fits naturally into everything from Oxford’s tree-lined neighborhoods to Biloxi’s coastal properties. A dedicated sun shelf, wraparound benches, and a wide entry landing pad give it purposeful features that work equally well for quiet afternoons and larger gatherings.
According to 2026 survey responses from independent Thursday Pools dealers throughout Mississippi, the average installed cost for a medium-sized fiberglass pool like the Sun Day is $70,000.

Mack Daddy is built for homeowners who want the full package. Thursday Pools’ first design to feature a fully integrated spa with a spillway, Mack Daddy also includes a spacious tanning ledge, a conversation area with wraparound benches and wide entry steps, and an open swim lane at uniform flat-bottom depth.
Larger Mississippi properties, whether in the spacious suburbs of Ridgeland or across the state’s more rural terrain, have room for a pool of this scale. The average cost for a standard installation of a large fiberglass pool like Mack Daddy in Mississippi is $80,000.
Mississippi’s varied landscape means site conditions can differ and impact a fiberglass pool project’s cost. Before breaking ground, a professional installer will assess your site for conditions that may require extra preparation.
Mississippi’s geology creates distinct challenges depending on where you are in the state. In the northeastern hills around Oxford and Corinth, rocky patches can require additional excavation labor and specialized equipment. Central Mississippi, including the Jackson and Madison areas, often has heavy clay soil that retains water and may require extra handling to ensure proper drainage and stable installation. Along the Gulf Coast near Biloxi and Gulfport, softer sandy soils can need reinforcement to keep the pool shell from shifting over time. A pre-installation site assessment identifies what your specific soil requires before the project begins.
Properties near the Natchez Bluffs, in the Ozark foothills, or anywhere with significant elevation change may need grading, retaining walls, or other leveling work before excavation can proceed. A relatively flat, level yard keeps installation more straightforward and predictable.
Wide, open access makes a fiberglass pool installation more efficient. Properties with narrow gates, tight side yards, or access restrictions common in older urban neighborhoods or historic areas may need specialty equipment, additional labor, or crane service to move the one-piece pool shell into position.

Homeowners building a private residential pool in Mississippi are subject to the barrier and fencing requirements set by their local municipality or county. Common baseline requirements include:
Local jurisdictions may adopt stricter requirements. For example, the City of Olive Branch requires detailed site plan submissions and a temporary code-compliant barrier during the installation period itself. Always verify current requirements with your local municipality, county building department, and HOA before installation.
For a 300-linear-foot basic pool fence, Mississippi dealers estimate an average cost of $13,500. Final pricing varies by material, height, gate requirements, terrain, and local code compliance.
Optional features can expand what your pool does and extend your swimming season throughout Mississippi’s long warm-weather months. The right upgrades enhance comfort, convenience, and safety while maximizing your investment. The averages below come from Thursday Pools’ 2026 dealer survey in Mississippi.
*Thursday Pools strongly advises against pool slides and diving boards due to safety concerns. The inclusion of a diving board or slide with any fiberglass pool must be carefully reviewed by a licensed professional to ensure compliance with all local building codes, safety regulations, and manufacturer guidelines. Not all fiberglass pool models are suitable for diving or slide use. It is the responsibility of the homeowner and installer to ensure proper installation and usage. Always prioritize safety and consult a qualified expert before adding any diving or sliding feature to your pool.
A fiberglass pool in Mississippi costs an average of $60,000 for a small pool, $70,000 for a medium pool, and $80,000 for a large pool, based on Thursday Pools’ 2026 survey of the state’s independent dealers.
A standard fiberglass pool installation in Mississippi typically includes:
Rocky soil in Mississippi’s northeastern hills, clay-heavy soil throughout central Mississippi, and sandy soil along the Gulf Coast can each require different levels of site preparation. The good news is that Mississippi’s relatively flat terrain outside its hilly northeastern and Natchez regions keeps slope-related costs modest for most of the state. Limited backyard access, such as narrow gates or tight side yards in older urban neighborhoods, can require crane service or specialty equipment. Based on the 2026 Mississippi dealer survey, site-condition upcharges range from about $400 for soil-related excavation challenges to $4,000 for navigating limited yard access.
Residential Mississippi pools are subject to the barrier and fencing requirements set by the local municipality or county. Most barriers must be at least 48 inches tall and no more than 2 inches off the ground, with self-closing and self-latching gates that open outward away from the pool. Local jurisdictions may adopt stricter requirements. Always verify current requirements with your local municipality, county building department, and HOA before installation.
The 2026 Thursday Pools survey shows an average cost of $13,500 for a 300-linear-foot basic fence in Mississippi, with final costs varying by material, height, gate requirements, terrain, and local code compliance.
