Fiberglass Pool Costs: Here Is How Much You Can Expect to Pay [2024 Data]

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 Cost Factors


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.

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 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.

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.


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.

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.

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.


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.

Operating Costs

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.
