How Much Does a Fiberglass Pool Cost in South Dakota?

Based on a 2026 survey of independent fiberglass pool builders in the Thursday Pools dealer network, a standard fiberglass pool installation in South Dakota averages $140,000 for a small pool, $145,000 for a medium pool, and $150,000 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.

The state’s geography creates variation in installation conditions. Eastern South Dakota, including the Sioux Falls metro, features flat to gently rolling terrain and clay-heavy soils common throughout the Coteau des Prairies. These conditions generally support straightforward installations. The Black Hills in the western part of the state present a dramatically different picture: steep slopes, rocky granite substrate, and challenging access conditions that require more preparation and more specialized equipment.

Optional features like pool heaters, automatic covers, and spas extend the South Dakota season and enhance the return on a meaningful investment. A local independent Thursday Pools dealer can evaluate your site, navigate local permit requirements, and help you build the right pool for South Dakota conditions.

What Do Popular Fiberglass Pool Models Cost Installed in South Dakota?

ASPEN (12′ x 25′)

Aspen is a clean, purposeful pool that delivers full functionality in a compact footprint. It’s a strong fit for the suburban lots common in Sioux Falls, Rapid City, and the residential communities spreading across Eastern South Dakota. A tanning ledge, open swim lane, and wide entry steps give Aspen the features that matter without requiring a sprawling yard. Its straightforward dimensions also make it one of the more efficient designs to install in South Dakota’s compressed construction season.

Based on 2026 feedback from Thursday Pools dealers throughout South Dakota, the average installed cost for a small fiberglass pool like Aspen or other designs less than 26 feet long and 400 square feet is $140,000.

 

CATHEDRAL (14′ x 33′)

Cathedral brings Roman-style elegance to mid-size South Dakota backyards, at home in the spacious suburban lots surrounding Sioux Falls, on larger properties in Rapid City and Brookings, and anywhere a homeowner wants a pool with real presence and timeless proportions. Grand entry steps, wraparound bench seating, and an open central swim lane make it as practical as it is polished.

According to 2026 survey responses from independent Thursday Pools dealers throughout South Dakota, the average installed cost for a medium-sized fiberglass pool like Cathedral is $145,000.

 

MACK DADDY (16′ x 36′)

Mack Daddy is built for South Dakota homeowners ready to go all-in on their outdoor living space. Thursday Pools’ first design to feature a fully integrated spa with a spillover, Mack Daddy also includes a spacious tanning ledge, wraparound benches, wide entry steps, and a flat-bottom open swim lane. It’s a natural choice for larger lots in the Sioux Falls metro, rural acreages in Eastern South Dakota, and any property where the goal is a backyard destination rather than just a pool.

The average cost for a standard installation of a large fiberglass pool like Mack Daddy in South Dakota is $150,000.

 

What Yard Conditions Affect Fiberglass Pool Installation Costs in South Dakota?

South Dakota’s varied landscape means site conditions can differ significantly between eastern and western parts of the state. Before breaking ground, a professional installer will assess your site for conditions that may require extra preparation.

Soil Type

South Dakota’s geology creates distinct challenges depending on where you are. Clay-heavy soils dominate eastern South Dakota, including the Sioux Falls metro and the agricultural communities of the Coteau des Prairies, where dense, moisture-retaining ground requires careful drainage planning during installation. In the Black Hills region around Rapid City, granite bedrock and rocky substrate create very different and more challenging excavation conditions that require specialized equipment. Sandy soils are less common, but appear in specific geological areas.

Slope and Grade

Eastern South Dakota’s flat to gently rolling terrain keeps slope-related costs relatively modest for most homeowners in the Sioux Falls market. The Black Hills are a different matter, with steep grades, challenging terrain, and the topography of the Rapid City area requiring significant grading, retaining walls, or leveling work before installation can proceed.

Backyard Access

Access challenges are most significant for rural properties, acreages in the Black Hills, and any site far from a major road corridor. The logistics of delivering a large one-piece fiberglass shell to remote South Dakota locations can require crane service or specialty transport.

 

AVERAGE ADDITIONAL YARD-RELATED EXPENSES IN SOUTH DAKOTA
Excavating Sandy Soil	$1,520
Excavating Clay-Heavy Soil	$5,000
Excavating Rocky Soil	$2,725
Above-Average Slope Requiring Extra Grading	$3,898
Limited Yard Access	$4,500

What Are South Dakota’s Swimming Pool Fence Requirements?

South Dakota’s residential pool fencing and barrier requirements are set and enforced by local municipalities. The City of Pierre, for example, requires pool enclosures through Article 1 of its Building Code, Section 3109.2.1. Pierre’s code exempts spas or hot tubs equipped with an ASTM F1346-compliant safety cover from barrier requirements, and allows the building official to approve alternative protective devices where the degree of protection is equivalent.

The City of Sioux Falls follows the International Residential Code (IRC) Appendix G pool barrier provisions, which require a minimum 48-inch barrier with self-closing, self-latching gates, no openings larger than 4 inches in any direction, and a maximum clearance of 4 inches between the bottom of the barrier and the ground. 

Requirements vary by municipality and may differ between Eastern and Western South Dakota. Always verify current pool barrier and fencing requirements with your local building department before installation.

For a 300-linear-foot basic pool fence, South Dakota dealers estimate an average cost of $15,000. Final pricing varies by material, height, gate requirements, terrain, and local code compliance.
