A fiberglass in-ground pool is one of the most valuable upgrades a homeowner can make, offering beauty, durability, and years of relaxation in the backyard. As more families in O’Fallon, MO embrace outdoor living spaces, fiberglass pools have become a preferred choice for those seeking long-term performance and low maintenance. Yet the most common question remains: How much does a fiberglass in-ground pool actually cost?
At Burke Construction, we believe pricing should be clear, straightforward, and backed by expert guidance. Understanding what goes into a complete fiberglass pool project helps homeowners make confident, well-informed decisions. While every backyard and project is unique, most turnkey fiberglass pool installations in O’Fallon fall within a general cost range when performed at a professional standard.
Average Fiberglass Pool Cost in O’Fallon, MO
A fully installed fiberglass in-ground pool—complete with excavation, the fiberglass shell, installation, equipment, and standard concrete border—typically ranges from $80,000 to $120,000 in O’Fallon, MO.
This price reflects the complete project, excluding optional upgrades and landscaping. The exact final cost depends on the backyard layout, pool size, soil conditions, and the amenities chosen to enhance the pool space.
Homeowners are often surprised to learn that fiberglass pools offer a strong balance between installation cost, long-term ownership expenses, and durability. Understanding the components of this investment helps illustrate the value behind the price.
What Is Included in a Fiberglass Pool Installation?
A high-quality fiberglass pool project consists of several essential steps, each of which contributes to long-term performance. At Burke Construction, we approach each installation with precision and craftsmanship to ensure lasting value.
Excavation and Site Preparation
Before any shell is placed, careful measurement and excavation are required. Soil conditions, property grade, and access points affect this phase. Proper excavation protects the shell’s placement and prevents shifting over time.
Fiberglass Pool Shell
The shell itself accounts for a significant portion of the cost. Premium shells offer durability, smooth surfaces, UV resistance, and a range of designs. Unlike vinyl liners, fiberglass shells require no liner replacement and have minimal upkeep.
Professional Installation
Installing a fiberglass shell is a specialized process. Operators must level the ground, set the shell precisely, secure it properly, and backfill it using the appropriate materials. Correct installation prevents bulging, settling, or structural issues.
Perimeter Concrete or Coping
Once the pool is set, concrete or coping is installed around the edges to create a finished look and secure the pool in place. This component defines the walking area and visually completes the pool perimeter.
Pool Equipment Package
A standard fiberglass pool installation includes:
- Filtration system
- Pump
- Plumbing
- Skimmer and returns
- Basic electrical setup
These systems allow the pool to function efficiently and stay clean throughout the season. Upgrades, such as variable-speed pumps or advanced automation, affect the final cost.
Additional Costs That Influence the Total Price
The $80,000 to $120,000 range reflects a full installation without extra customization. Homeowners may choose upgrades that enhance the entertainment experience, which influence the overall budget.
These may include:
- Waterfalls or deck jets
- Premium coping styles
- Expanded patio areas
- LED lighting packages
- Fencing (often required by local code)
- Pool heaters or chillers
- Landscaping
These additions are optional but can elevate the space into a personalized backyard retreat.
Why Fiberglass Is a Strong Investment for O’Fallon Homeowners
Fiberglass pools offer one of the best long-term values in the industry. Unlike vinyl liners, which require replacement every seven to ten years, fiberglass requires significantly less maintenance and incurs fewer major expenses over time. The gelcoat surface is smooth, algae-resistant, and extremely durable.
The result is a pool that is not only beautiful from the day it is installed, but cost-effective throughout its lifespan.
