Cost Estimator by Pool Size

The size of your pool is a major factor affecting the total cost of installation. As with any type of pool, increasing the size will raise the price due to high labor and material costs. On average, a fiberglass in-ground pool costs $132 per square foot

A small 200-square-foot pool can cost about $26,400, which is lower than the national average. A large fiberglass pool that measures 800 square feet will bring the price closer to the high-end, costing homeowners about $105,600

Other Factors That Affect Cost

The size and design of fiberglass pools are not the only factors affecting the total installation cost. The pool’s location on the property, permits required to complete installation, and other factors incur additional charges. 

Such factors include:

Pool type

In-ground pools generally come in various designs or shapes, affecting the overall cost of the fiberglass pool. The type of pool you choose to install will also determine the amount of long-term maintenance costs.

A complex design, such as a lagoon pool, generally costs more than getting a standard pool installed. This is mainly because complex pools with unique designs require more materials to construct, allowing pros to charge more and raising the overall cost of installation. 


Most in-ground pools require a permit before installation, with prices varying between $475 and $1,900. The amount you spend on a permit depends on which city, county, or state you live in. 

While pool builders might provide some information, it is generally your responsibility to determine the need for a permit. 

Pool location

Before installing your in-ground pool, pool building professionals will need to excavate the land. Excavation can be quite expensive, adding a significant amount to the installation cost. 

There are several examples of how your pool site could affect cost:

  • If your property’s soil is rocky, it could damage the equipment used by pros to excavate the land. Such occurrences could lead to an increase in the cost of installation. 
  • If the installation site is in a hard-to-reach area, extra measures could be taken to transport the fiberglass pool shell and excavate the land. These extra measures could add more costs to the bill. 
  • Clearing the land when an existing landscaping is blocking the site. This could include tree removal costs ranging anywhere from $385 to $1,070 per tree.
  • Sloping and grading if the pool site is located on a hill, leading to higher costs. 

Pool maintenance 

Fiberglass pools are the easiest to maintain. Generally, professional pool maintenance costs between $2,000 and $4,035 annually. Annual fiberglass pool maintenance is cheaper than other pool types, with prices varying between $375 and $600.


Pool companies sometimes pack pool installation and other related services into one package, allowing you to pay a flat amount rather than paying for each service separately. 

Large package plans could seem quite expensive at first, but you end up getting the pool and several outdoor services at reduced rates. These outdoor services or installations can include pool decks or fences. 

To learn more about package plans and the services they include, contact your local professional pool builders.  

Increased insurance

Fiberglass pools can unfortunately cause swimmers to slip and fall, mainly due to the smooth surface. In fact, in-ground swimming pools can generally increase the risk of guests or family members getting hurt on your property. This type of increased risk on your property will raise your insurance costs. 

Increased property taxes

Unlike above-ground pools, in-ground pools are a permanent installation on your property. It is also worth noting that this pool type can increase your home’s resale value, meaning that the added value will lead to an increase in property taxes. 

Add-Ons and Extra Services

These additional services can really spruce up your property, particularly your backyard space. However, some of these add-ons can bring the total cost of pool installation closer to the high-end price. 

Examples of these extra services include:

Pool decking

Pros typically charge between $3,600 and $15,733 to install a deck around your fiberglass swimming pool, with costs depending on its size and material. Pool decks will benefit your pool area by providing a sturdy foundation to get a tan, enjoy barbecues, and dry off without getting your feet dirty. 

Pool fencing

Building a fence around your pool will improve your backyard’s privacy and security. A fence can also prevent children and pets from wandering dangerously close to the fiberglass in-ground pool, lowering the risk of drowning or other harmful outcomes. On average, installing a pool fence costs between $1,350 and $6,985

Some common fencing materials include:

  • Tempered glass
  • Aluminum
  • Plexiglass
  • Chain-link
  • Mesh
  • Wood
  • Ornamental designs

Pool lighting

Installing lights in your fiberglass pool has several advantages:

  • Safely get in and out of the pool after dark
  • Increase the pool’s visibility in the dark
  • Set the mood for a relaxing evening outdoors

The typical price range for pool lighting is approximately $617 to $1,567. Fiber optics are generally priced much higher than LED lights. 

Pool tiling

Pool tiles can give your fiberglass in-ground system a fabulous design that can rival any one of your neighbors’ pools. The most common pool tiles are porcelain, natural stone, and glass. 

TileAverage cost
Porcelain $2 – $50 per square foot
Natural stone$5 – $30 per square foot
Glass $7 – $50 per square foot


As outdoor temperatures begin to drop, adding a heater to your fiberglass pool can lengthen the swimming season. A pool heater costs $1,718 to $4,426 on average. 


You can revamp your outdoor in-ground pool’s landscape by installing a pathway, planting flower beds, or attaching a pergola

Landscaping serviceAverage Cost
Pergola installation$2,100 – $6,000
Gazebo installation$5,365 – $9,025
Pathway installation$8 – $22 per square foot
Flower bed planting$650 – $3,000 per flower bed
Tree planting$25 – $3,000
Sod installation$0.87 – $1.76 per square foot
Retaining wall$3,600 – $9,500

Saltwater conversion

Saltwater pools have become a popular choice. They are gentle on the skin and cheaper to maintain than conventional chlorine pools. Converting your chlorine pool to a saltwater system typically costs between $500 and $2,110

Fiberglass Pools Compared to Other Pool Types

Fiberglass pools may cost higher than vinyl-liner pools, but their low maintenance and long-term costs may be enough to convince homeowners of selecting this pool type over the others. Concrete or gunite pools are generally more expensive than vinyl-liner and fiberglass pools, with prices ranging between $31,000 and $71,665.   

MaterialTypical Range
Vinyl-liner$24,000 – $44,000
Fiberglass$24,335 – $70,000
Concrete$31,000 – $71,665

Pro Cost vs. DIY Cost

FAQ About Fiberglass In-Ground Pools

Should you drain your fiberglass pool? 

Most professional pool builders and installers agree that you should never drain your in-ground pool. The weight of the water helps hold the fiberglass panel in place, and ignoring the professional’s advice could void the pool’s warranty. Pros will handle this complex task only if your pool requires major repairs or needs to go through draining and refilling every 5 to 7 years. 

Can fiberglass in-ground pools withstand harsh weather conditions? 

Generally speaking, fiberglass pools are the best choice for cold climates. With properly winterized plumbing, fiberglass pool owners should not worry when harsh weather conditions hit the area. The material itself has a high strength-to-weight ratio, so it’s quite durable and resistant to damage.  

What can damage fiberglass pools? 

Despite their durability and low maintenance requirements, fiberglass pools can still be damaged if not properly taken care of. Imbalanced minerals or chemicals, too much chlorine, or high amounts of metallic objects can cause stains to appear, for example. 

When to Hire a Professional Pool Builder

If you wish to build a swimming pool with quick installation, low maintenance costs, and a potential to increase your home’s resale value, then a fiberglass in-ground pool is the best choice for you. With an average cost of $47,000, this type of pool is a worthwhile investment that allows you to spend quality time with your friends and family. 

Fiberglass pools may not be as aesthetically pleasing as concrete or gunite pools, but certain designs, such as infinity pools, can be just as stunning.
