Fiberglass pool installation cost factors
A fiberglass pool is a significant investment, and several factors influence the final price:
Pool depth: Deeper and larger pools use more materials and require additional labor, which raises the overall cost. Most pools are between 3 and 6 feet deep, with some deep ends reaching 5 to 9 feet.
Design complexity: Unique shapes, infinity edges, and luxury features like tanning ledges or built-in spas add to the project’s expense.
Site conditions: Challenging terrain like slopes, rocks, or poor soil can drive up excavation and preparation expenses.
Permits and inspections: Municipal requirements for permits and inspections can range from $100 to $300 or more, depending on your location.
Labor rates: Costs for skilled labor vary by region, with contractors in metropolitan and high-cost-of-living areas charging more for installation.
Utilities: Installing electrical and plumbing systems for pool equipment and heating can significantly increase total project costs.
Water: Filling your pool with water costs $40 to $2,000, depending on whether you're using a garden hose to fill from a well or the public water supply or getting professional water delivery.
Features or upgrades
Adding features to your pool increases the overall cost. Popular enhancements include lighting, heating, and automation systems. High-end additions such as spas, waterfalls, and custom decking further raise the price.
| Feature | Average cost |
|---|---|
| Pool heater cost | $1,600 – $5,200 |
| Pool chiller cost | $2,000 – $5,000 |
| Pool waterfall cost | $2,000 – $8,800 |
| Inground hot tub cost | $6,000 – $25,000 |
| Pool enclosure cost | $4,000 – $30,000+ |

| Pool lighting | $1,500 – $5,000 |
| Pool automation system | $1,500 – $3,500 |
Landscaping and other additions
Since installing a pool is a complex process, your yard may need some repairs or modifications before or after the project:
A pool deck costs $25 to $50 per square foot, depending on the material you choose.
Sod installation costs $1 to $2 per square foot.
Fence installation costs $20 to $60 per linear foot for privacy and safety. Some cities mandate that all residential pools have a safety fence. Check your local regulations to confirm.
Maintenance costs
Owning a fiberglass pool comes with the following ongoing expenses:
Maintenance: Professional pool maintenance costs $80 to $150 per month, depending on the pool size and frequency of visits.
Chemicals: Pool chemicals cost $175 to $750 per year on average and keep your pool clean and algae-free.
Insurance: Homeowners insurance can increase by $50 to $100 per year after installing a pool due to the increased risk and liability.
Fiberglass pool prices vs. other inground pools
The cost to build a pool ranges from $35,000 to $120,000 on average, depending on the type. Concrete (gunite) pools are the most common building material for inground pools, followed by fiberglass and vinyl liners. The table below shows the average total cost for each pool type
| Material | Average total cost | Longevity |
|---|---|---|
| Concrete | $50,000 – $120,000 | 50+ years |
| Fiberglass | $45,000 – $100,000 | 25+ years |
| Vinyl Liner | $35,000 – $80,000 | Liner replacement every 10 years |
Concrete
A concrete or gunite pool costs $50,000 to $120,000 with installation. Concrete pools offer greater customization and durability than fiberglass shells. Installers can create almost any shape or size and can finish with standard plaster or premium tile.
These pools take longer to install and cost more up front, but they can last decades with proper maintenance.
Vinyl
A vinyl liner pool costs $35,000 to $80,000 total. Vinyl liner pools are an affordable inground option, using a flexible liner over a steel or polymer frame. The initial investment is lower than concrete or fiberglass.
However, the liners wear out and need to be replaced every 7 to 10 years. Replacing a vinyl liner costs $2,000 to $7,500, depending on the pool type and size.

Fiberglass pool FAQs
What is a fiberglass pool?
A fiberglass pool is a prefabricated, one-piece shell made from layers of fiberglass reinforced with resin. Manufacturers build these pools in a controlled factory environment then deliver the finished shell to your home for installation. The smooth, non-porous surface resists algae and reduces maintenance compared to concrete or vinyl pools.
How long do fiberglass pools last?
Fiberglass pools last 25 years or more with proper care. The durable, flexible shell resists cracks and structural problems, while the gelcoat finish protects against fading and chemical damage. Many manufacturers offer warranties that reflect the pool’s expected lifespan.
Are fiberglass pools good?
Fiberglass pools offer several advantages: they require less maintenance, install quickly, and provide a smooth, algae-resistant surface. Their durability and energy efficiency make them a popular choice for homeowners seeking long-term value and reliability. However, shape and size options are more limited than with custom concrete pools.
Can fiberglass pools be salt water?
Yes, you can use a saltwater system with a fiberglass pool. The non-porous gelcoat surface resists corrosion and is compatible with salt chlorine generators, making fiberglass an excellent choice for saltwater pools.
How deep is a fiberglass pool?
Fiberglass pools come in various depths, ranging from 3 feet in the shallow end to 5 to 9 feet in the deep end. Some models offer sport or play pool designs with uniform depths, while others feature deep ends suitable for diving. The specific depth depends on the manufacturer and model selected.
