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 most homeowners could pay anywhere between $25,065 and $48,995. 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.
The cost of fiberglass in-ground pools can range from as low as $5,000 to $57,000 or more on the high end. Challenging locations, like hilly yards, can raise the price, and you will need to budget for permits as well. Read on to discover all of the ins and outs of the costs to build a pool.
Fiberglass pool installation costs around $15,000 for a simple plunge pool to over $75,000 for above-ground pools or zero-entry pools. If you are looking for a space to get your daily exercise, a lap pool runs around $30,000 to $65,000.
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 |
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 |
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. We recommended discussing labor costs with the pool installation company during the planning stages of the project.
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 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.
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.
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.
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.
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 |
| 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 |
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.
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.
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.
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.
Expect to pay $30,000 to $75,000 for 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.
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.
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.
Fiberglass pool maintenance costs about $600 to $1,200 per year for regular cleanings. Fortunately, fiberglass pools tend to require less maintenance over their lifespans compared to other pool types, like concrete or vinyl liner pools.
Opening a pool costs around $300 to $400. Closing a pool for the winter costs about $150 to $300. Aside from regular cleaning costs, you will need to open your pool at the start of the season and close it for winter to keep the equipment in good condition.
Fiberglass pool repairs cost from $300 to fill small cracks or fix fading colors to about $6,500 to refinish the fiberglass shell. You may also want to repaint the pool from time to time, which costs around $800.
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. Learning how to build a pool is an extensive process that requires a wide range of skill sets. Generally, you should leave this job up to the pros.
Having a pool is fine, but it is not as fun without add-ons like diving boards, slides, or waterfall features. For safety and functionality, you will likely want to include 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 |
Installing a fiberglass pool can be a large upfront investment, but there are some ways to save money on this project.
The smaller the fiberglass pool, the lower the cost. If you do not care to swim or dive, you may opt for a small plunge pool that is only a few feet deep and starts around $15,000 for materials and labor.
Manufacturing and installing custom fiberglass pools or those with curvy perimeters cost more than simple rectangular pools. You can save by installing a square or rectangular pool if your landscape allows for it.
If you can do without all the bells and whistles, you will save more on your pool. 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.
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.

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.
