How Much Does a Fiberglass Pool Cost to Install? [2025 Data]
The average fiberglass pool costs $33,270, but it can range between $25,065 and $48,995, depending on size, type, and any extras.
Installing a fiberglass pool costs $33,270 on average, though homeowners could pay anywhere between $5,000 and $68,000. Larger fiberglass pools with curving sides or custom shapes and add-ons like diving boards, controlled temperature settings, or waterfall features land on the higher end of the range, while smaller rectangular fiberglass pools cost less.
Installation Costs by Pool Type
There is a fiberglass pool design to fit most preferences and needs, so let’s review how much homeowners can expect to spend for each type of pool.
| Pool Type | Cost Range |
|---|---|
| Above-Ground | $20,000–$75,000 |
| Inground | $40,000–$100,000 |
| Lap | $30,000–$65,000 |
| Saltwater | $20,000–$60,000 |
| Infinity | $40,000–$70,000 |
| Zero-Entry | $30,000–$75,000 |
| Plunge | $15,000–$40,000 |
Above-Ground
Fiberglass pools installed at least partially above ground need additional support so that they stay level and do not crack over time. That is why they are installed with a structure around the shell, resulting in the entire project costing $20,000 to $75,000.
Inground
Inground fiberglass pools are installed below ground level. They are a prefabricated, one-piece fiberglass shell that a local inground pool contractor places into a pre-dug hole. Like all fiberglass pools, they have a smooth gel coat finish and are installed quickly. However, the added excavation costs make them more expensive to install, so expect to pay $40,000 to $100,000.
Lap Pool
The average cost of a fiberglass lap pool is $30,000 to $65,000. Lap pools are long rectangular pools best used for swimming laps. Since they usually measure 40 feet by eight feet, their narrow design makes them a great candidate for small properties.
Saltwater Pool
To install a fiberglass saltwater pool, you can expect to pay between $20,000 and $60,000. These pools rely on salt instead of chlorine to keep the water clean. This type of pool works particularly well with fiberglass because salt will not damage the material.
Infinity Pool
Swimming pool shapes other than the usual rectangular one will cost more. An infinity pool is a pool with an exposed side that gives the illusion of extending toward the horizon, ocean, or backyard. It will cost an average of $40,000 to $70,000 to install this elegant type of pool.
Zero-Entry
Expect to pay $30,000 to $75,000 for a zero-entry pool. This convenient type of pool, which allows you to walk in from the shallowest side or the deepest end, no climbing ladders or steps required.
Plunge Pool
The average cost for a fiberglass plunge pool is $15,000 to $40,000. While plunge pools are not made for swimming, their small size—six by 12 feet wide, and just four to six feet deep—makes them perfect for small properties and quick dips to cool off in warmer months.
Size
Fiberglass pool installation costs about $800 per linear foot for the materials, or about $1,200 per linear foot with labor included.
| Pool Size (feet) | Average Cost |
|---|---|
| 10x20 | $26,000 |
| 12x20 | $32,500 |
| 15x30 | $48,500 |
| 16x32 | $51,500 |
| 16x40 | $58,500 |
| 20x40 | $62,500 |
Materials
Fiberglass pool materials cost around $5,000 to $55,000 for materials. Fiberglass pool shells cost $4,500 to $30,000, and the pump and filtration system cost $1,200 to $4,500. For backfill, gravel will cost about $1 to $3 per square foot. You will also need water, of course, which costs about $60 to $120 for a standard 15,000- to 30,000-gallon swimming pool.
| Fiberglass Pool Materials | Average Cost |
|---|---|
| Shell | $4,500–$30,000 |
| Pump and Filtration System | $1,200–$4,500 |
| Backfill Gravel | $1–$3 per square foot |
| Water | $60–$120 |
Pool Contractor Costs
A major cost involved with installing a fiberglass pool is paying professionals to do the installation. You can expect to pay about $5.50 per square foot in labor costs, or about $10,000 to $20,000 in total. Most companies, however, quote homeowners for a five-person crew at 160 labor hours. Add labor costs to the list of questions to ask your pool contractor during the planning stages of the project.
Location
The cost of labor and materials varies from state to state. Here is what you can expect to spend to install a new fiberglass pool in the following areas:
| State | Average Fiberglass Pool |
|---|---|
| Florida | $50,000–$95,000 |
| California | $45,000–$85,000 |
| Arizona | $30,000–$60,000 |
| Texas | $50,000–$85,000 |
| North Carolina | $50,000–$75,000 |
| Indiana | $55,000–$85,000 |
| Pennsylvania | $45,000–$90,000 |
| Ohio | $65,000–$90,000 |
| New York | $55,000–$85,000 |
| New Jersey | $50,000–$90,000 |
In warmer states, competitive local markets and favorable weather can help keep installation prices moderate. Meanwhile, lower labor and material costs in some areas keep averages near the lower end of the spectrum. In the Midwest and Northeast, factors like challenging climate, local permitting, and labor costs can force costs higher than the national average for fiberglass pool installation.
Additional Costs to Consider
While the costs above apply to most fiberglass pool installations, there are additional costs that your pool may incur. Here is the breakdown of other expenses you can anticipate.
Prep
The average pool excavation cost is $3,200. Excavating a yard to prepare for fiberglass pool installation costs anywhere from $400 for smaller sites and properties with soil that is soft and easy to work with to $20,000 for more difficult sites.
Permits
Permits to install a pool typically cost $100 to $300. If you are adding a patio or deck, you may need additional permits that cost $100 to $500 per project.
Decking
Swimming in a pool is great, but so is lounging poolside. You can expect decking to range between $3,000 and $12,000, depending on the size. A smaller deck between 300 and 600 square feet costs $1,000 to $5,000, while a midsized deck that is 600 to 900 square feet is $3,000 to $8,000. If you opt for a wraparound deck that is 900 square feet or more, then it could cost $7,000 to $12,000.
Fencing
A pool fence is a great idea because you do not have to worry about unattended pets or children wandering into the pool area. Pool fences cost $1,500 to $10,000. The price depends on pool size and fence type. Generally, you can expect a fence to cost $15 to $25 per linear foot, so you can estimate how much it will cost based on the size of your pool.
Landscaping
You can level up your pool area with nice landscaping. Turn your pool area into a lush, jungle-like oasis or keep it streamlined with native plants. Depending on the kind of work you do, expect it to cost $3,000 to $5,000, or $4 to $12 per square foot.
Ongoing Expenses of Fiberglass Pools
Once the fiberglass pool is installed in the backyard, you will still need to set aside a pool budget for ongoing costs, like regular cleanings, operations, and potential repairs.
| Type of Ongoing Cost | Average Amount Per Year |
|---|---|
| Maintenance | $600–$1,200 |
| Operating costs | $450–$700 |
| Repairs | $300–$6,500 |
Maintenance: Expect to spend $600 to $1,200 per year for cleaning.
Operating costs: Opening a pool costs $300 to $400, while closing a pool for the winter costs $150 to $300. Aside from cleaning costs, opening your pool at the start of the season and closing it for winter help keep equipment in good condition.
Repairs: Fiberglass pool repairs cost about $300 to fill small cracks or fix fading colors to about $6,500 to refinish the fiberglass shell. Repainting costs around $800.
Cost of Common Fiberglass Pool Add-Ons
Having a pool is fine, but it is more fun with add-ons like diving boards, slides, or waterfall features. Heaters and pool chillers can make your pool more comfortable. For safety and functionality, consider including lighting, handrails, and ladders. In total, these extras can cost $100 to $22,000, with most pool accessories costing up to $3,800 each.
| Pool Add-On | Cost Range |
|---|---|
| Lights | $700–$1,800 |
| Rails | $100–$500 |
| Ladders | $100–$2,000 |
| Heating and Cooling Pumps | $2,100–$4,500 |
| Covers | $760–$2,500 |
| Diving Boards | $500–$2,000 |
| Slides | $100–$10,000 |
| Waterfalls | $200–$6,000 |
Cost to Install a Fiberglass Pool Yourself vs. Hiring a Pro
Extremely handy and experienced homeowners can install a fiberglass pool as a DIY project, but in the vast majority of cases, and for most types of pools, it is better to hire a local swimming pool contractor. Without the experience and know-how to install everything yourself, you may end up paying thousands of dollars to hire a professional to fix any installation errors. The type of installation requires extensive experience with various components, such as:
Planning the pool layout
Operating heavy machinery like an excavator
Installing the plumbing system
Leveling the pool’s shell
If you install a fiberglass pool by yourself, you can save between $10,000 and $20,000 in labor fees, depending on factors like the pool shell, filter pump, backfill material, and permits. However, learning how to build a pool is an extensive process that requires a wide range of skill sets, so all but experienced pool contractors should leave this job up to the pros.
How You Can Save Money on Fiberglass Pool Installation Costs
Installing a fiberglass pool can be a large upfront investment, but there are some ways to save money on this project.
Go Small
The smaller the fiberglass pool, the lower the cost. If you are more into soaking than swimming or diving, you may opt for a small plunge pool that is only a few feet deep and starts around $15,000 for materials and labor.
Opt for Basic Shapes
Manufacturing and installing custom fiberglass pools or those with curvy perimeters cost more than simple rectangular pools. Save by installing a square or rectangular pool if your landscape allows for it.
Keep It Simple
You will save more on your pool if you can do without all the bells and whistles. Consider just adding enough ladders and lights to make swimming feel safe any time of day or night. Or instead of buying expensive extras like a separate hot tub, try adding less expensive add-ons like a heat pump for a similar effect at a lower cost.
Look for Off-Season Deals
The best time of year to buy pools and pool equipment is usually fall and winter, when peak swimming season is long gone. You will usually be able to find off-season sales, whether you want to purchase an entire pool or just save on extras like diving boards and lighting.
Are Fiberglass Pools Worth It?
Fiberglass pools can be a smart investment for homeowners who want a low-maintenance, long-lasting swimming pool. Unlike concrete pools that require resurfacing and more frequent chemical balancing or vinyl liner pools that need regular liner changes and are easier to damage, fiberglass pools have a smooth, non-porous, hard surface that resists algae growth and stands up to a lot of use.
While they have some downsides, like being more expensive upfront than vinyl liner pools or having limited customization options due to being pre-formed, the upsides can outweigh the cons. Most homeowners find that the reduced maintenance costs and long lifespan make fiberglass pools a smart choice in the long run.

Frequently Asked Questions
A fiberglass pool lasts up to 30 to 50 years with proper maintenance. For the longest possible lifespan, keep your pool water pH as close to seven as possible. Test your water levels regularly, run your pool filter daily, and avoid draining the pool. Once your pool is 20 to 30 years old, you can prolong the lifespan by refinishing the shell.
The amount of time your fiberglass pool project will take depends on the size of the pool and whether you are installing add-ons like decking and landscaping. Overall, you should expect it to take four to six weeks to install. If you are dreaming of summer pool parties, make sure to budget enough time into the installation schedule to have your pool up and running in time for the swimming season.
If you are installing a fiberglass pool, you may want to install or update your patio or deck at the same time to create a safe, comfortable place to sit and dry off or grab a bite to eat after swimming. You might also consider adding a hot tub to the mix, which costs $6,000 on average.
When looking into fiberglass vs. concrete pools, you will notice a big price difference. A fiberglass pool costs $15,000 to $75,000, whereas a concrete pool costs $35,000 to $100,000. While concrete pools are customizable, fiberglass is faster to install and requires less maintenance. Additionally, you can expect to pay $25,000 to maintain a concrete pool over a ten-year span. On the other hand, a fiberglass pool only requires basic maintenance like testing water levels and cleaning.
