An in-ground fiberglass pool costs an average of $29,178. Costs for this type of pool can range from $15,000 for a smaller, rectangular pool to over $75,000 for a larger fiberglass pool with additional features, like a heat pump, security cover, or decking. Your location and the size and shape of your pool will also influence the overall budget.

2022 Notice: Material Prices Are Surging

Demand for pool and other building materials has grown over the past year. And as a result, manufacturers are increasing materials prices. Prices have gone up 5% to 10% this year, and many parts of the country are experiencing long delivery times. If you're planning a building project, we recommend starting as early as possible in the season, preparing for potential price fluctuations, and allowing extra time to order materials.

Fiberglass Pool Costs by Type

The $15,000 to $75,000 price range depends on the size and shape you choose. It splits into materials at $5,000 to $55,000 and labor for professional swimming pool installation in your area at $10,000 to $20,000. Materials include the shell, backfill, and necessary equipment like a filter, heat pump, and cooling pump.

In-Ground vs. Above-Ground

In-ground pools are usually more expensive than above-ground, but expect to pay between $20,000 and $75,000 for a fiberglass pool that’s at least semi above-ground. This is much higher than the typical cost of an above-ground pool ($700 to $5,000). Fiberglass needs more support to avoid cracks and stay level, requiring a structure around it that keeps everything in place.

All fiberglass shells can be half-above ground, but only with the proper support around them. The material is not designed to hold up on its own above the surface. Ask your installation company about your options.

Lap Pool

The price of a lap pool ranges between $30,000 and $65,000. Its narrow shape is perfect for small properties, taking up only about 40 feet by 8 feet, and it’s usually around 4-feet deep.

Saltwater

Saltwater pool prices range between $20,000 and $60,000. Fiberglass is great for this option because the salt will not damage or compromise the material.

Infinity

The typical budget for an infinity pool ranges between $40,000 and $70,000. Also known as zero or negative edge, these types of pools add elegance by blending the edge of the water with the horizon. Fiberglass and custom tile are the most common building materials.

Zero-Entry

Expect to pay between $30,000 and $75,000 for a zero-entry pool. This option is also known as a walk-in, offering a smooth path to enter rather than steps or a ladder. The water at the shallow end is typically warmest.

Plunge Pool

The price of a plunge pool ranges between $15,000 and $40,000. It's a more cost-effective option for small properties and budgets. The basin measures 6-by-12 feet and is 4 to 6 feet deep.

Prefab vs. Custom

Fiberglass pool shells are manufactured, so the shape and size of these pools are not customizable like vinyl or concrete pools.

Converting Vinyl to Fiberglass

Expect to pay between $40,000 and $65,000 to replace a vinyl liner with fiberglass. That's more expensive than installing an in-ground pool from scratch in most cases. The reason for the greater expense is the increased workload. 

The price of removing a pool’s vinyl liner alone can range up to $2,000. Access to the installation site is typically more difficult. You might need to dig up more space for the stones to backfill around the new shell, as vinyl-lined pools are usually bigger than fiberglass.

Shell Only

The average cost of a fiberglass pool shell is around $8,750, but prices can range from $4,450 to $40,000. Small shells, less than 26 feet long, cost up to $30,000. Larger shells over 35 feet long cost $30,000 to $40,000.

15x20$30,000 – $60,000
15x30$32,000 – $65,000
16x32$35,000 – $68,000
16x40$45,000 – $72,000
20x40$50,000 – $75,000

Fiberglass Pool Cost Factors

Fiberglass pool costs vary greatly for a number of reasons. Size plays a big part in the project cost, but difficult sites or add-ons like heat pumps and other accessories can also raise the cost. Fortunately, fiberglass pool owners will save when it comes to maintenance, which is less for this type of pool compared to vinyl or concrete.

Pool Size

Fiberglass pools cost about $800 per linear foot, with costs ranging from about $15,000 for a spool pool (a small pool, also called a cocktail pool) and up to $75,000 for a large, 20-foot-by-40-footpool.

Location

More challenging locations with rocky soil or trees in the way will cost more for excavation. Prices tend to be lower in rural areas or southern states, while you may pay more if you live in an urban setting or in a northern state.

Labor

A pool company will charge between $10,000 and $20,000 for the installation. 

That price includes:

  • Shell

  • Shipping

  • Excavation

  • Filter pump

  • Backfill

  • Filling the pool

It does not include decking, fencing, and other optional add-ons like lighting, fountains, or an automatic cover.

Labor alone will be around $5.50 per square foot, or $1,500 total for about 275 square feet. Most companies base their quote on a five-person crew at 160 labor hours, taking the size of the pool into account. Ask the installer whether labor costs are included in the quote.

Heat Pump

Pool heat pumps cost$1,500 to $3,500, including installation. Adding a cooling pump to maintain a specific temperature range adds another $600 to $1,000.

Filtration System

A filtration system for a fiberglass pool costs about $500 to $3,000. You’ll need filters to keep your pool clean.

Filling Pool

Once the pool is built, you’ll need to spend $60 to $120 to fill a standard-sized 15,000- to 30,000-gallon swimming pool. In drought-prone areas, you may be charged an additional $100.

Excavation

Land excavation costs an average of $3,400. Costs are lower, around $400 to $1,500, if the soil is soft and manageable. More challenging project sites can cost up to $20,000 for excavation.

Liner

Pool liners range between $4,500 and $30,000. Unlike vinyl, it's a completely finished hard shell by the time it's shipped to your property.

Pool Accessories

Be sure to budget between $100 and $22,000 for accessories to get the most enjoyment from your fiberglass pool. 

While your costs will likely fall somewhere in between, this range covers the most basic slide to the most expensive automatic pool cover. The price of optional pool accessories can go up to $3,800 each

Pool accessories include the following: 

  • Slides

  • Diving boards

  • Handrails and ladders

  • Mosaic tile

  • Security covers

  • Automatic covers

  • Surface colors

  • Lighting

  • Fountains

  • Waterfalls

  • Hot tubs

  • Jets

  • Automatic vacuum systems

  • Retaining walls

  • Salt chlorine generators

Exact prices depend on the accessory as well as its size, style, and manufacturer. Shop around for your best deals and ask if the quote includes installation.

Decking

Budget about $5,000 to $12,000 for a new deck around the pool. Decking costsare $4 to $20 per square foot, and the most commonly used material is concrete. Choices go from a rough broom finish ($4 to $8 per square foot) to stamped concrete and pavers ($11 to $20 per square foot).

Tile

Anticipate pool tile costs to sit between $2,000 and $70,000, depending on materials. Standard pool tiles, like ceramic, stone, and porcelain, cost $1 to $35 per square foot. High-end finishes, like glass or ceramic tiles, cost between $35 and $100 per square foot.

Tile MaterialCost per Square Foot
Granite$5 – $6
Marble$10 – $20
Travertine$3 – $30
Limestone$2 – $11
Glass$7 – $50
Mosaic$75 – $100
Ceramic$1 – $35
Porcelain$2 – $56

Lighting

Installing lights around your fiberglass swimming pool costs $600 to $1,600, depending on which type you choose. LED—one of the most popular options—comes in toward the bottom; fiber optic lighting sits at the top of the range. While considered an add-on, investing in lighting is always a wise choice for safety, ambiance, and character.

Pool House

A 300-square-foot pool house costs $114,000 on average, although costs range from $48,000 to $180,000. The cost is about $160 to $600 per square foot, with higher costs for pool houses complete with bathrooms and kitchens. Anticipate spending $34,200 to $68,400 just for labor, or roughly 30% to 60% of the cost to build a pool house.

Pool Enclosures

Pool enclosures cost an average of $10,200 for a 700-square-foot enclosure. Most people pay $5,300 to $15,300, though glass pool enclosures cost $38,500 or more. Expect to pay more than $70,000 for a high-end, retractable pool enclosure.

  • Screen enclosures: $14 per square foot

  • Glass enclosures: $55 per square foot

  • Retractable: $100 or more per square foot

Additional Landscaping

On average, landscaping costs $1,500 to $5,200, depending on many variables, like a sloping yard, types of plants or grasses, or whether you need stump removal or a retaining wall. Basic landscaping projects cost $2 to $6 per square foot, intermediate projects cost $6 to $10 per square foot, and full tear-out and remodel projects cost $10 to $40 per square foot.

Ongoing Maintenance

The price to maintain your pool ranges between $120 and $380 per cleaning, or about $400 to $600 total per year. That's relatively low compared to other options. A concrete liner, for instance, costs up to $2,700 per year to maintain.

Some installers offer maintenance programs for as little as $15 per month. It’s critical to maintain your pool regularly to avoid major repair costs down the road.

Fiberglass vs. Other Pool Materials

The cost of a fiberglass pool is similar to the price of a concrete or gunite pool, which costs about $35,000 to $65,000. Vinyl pools cost less, at about $20,000 to $40,000.

Although they aren’t the least expensive, some benefits of fiberglass pools include faster installation time and less maintenance. On the other hand, the shape is less custom and the lifespan (25 years) is about half the 50-year lifespan of a gunite cast.

Common Fiberglass Pool Repairs

DIY vs. Hiring a Pool Professional

DIY fiberglass pool installation ranges between $5,000 to $55,000. You save all professional labor costs, but this option only makes sense if you have extensive expertise and experience in preparing your property and placing the shell. Installing a fiberglass pool incorrectly could lead to costly damage, so this project is best left to a pool professional.

FAQs

Is a fiberglass pool worth it?

It all depends on what you want from your fiberglass pool. If you’d like a lower-maintenance pool (relative to other types) with greater energy efficiency and a relatively quick installation timeframe, then a fiberglass pool could be worth your investment. 

How long do fiberglass pools last?

You can expect about 25 years from your fiberglass pool with relatively little maintenance. If you don't maintain its pH levels, that lifespan can drop to 10 years or less as the chemicals damage the shell.

What's the most affordable fiberglass pool shape and type?

The least-expensive shape tends to be a simple rectangle that's no longer or wider than 20 feet. Most installation companies either have it in stock or can order it quickly from their preferred manufacturer.

Are there downsides to a fiberglass pool?

Fiberglass pools can cost as much as or more than other common pool types, like concrete. But poor installation is the biggest potential downside. Fiberglass pools are pre-manufactured, meaning they arrive ready to install. If your contractor doesn’t have experience installing fiberglass pool shells, they may not install it correctly.

Poor installation can lead to an expensive and headache-inducing journey to remedy the problem—assuming a solution exists. Before you hire a local fiberglass pool installer, be sure to explore multiple pros’ reviews and reach out to at least three for quotes.
