Fiberglass Pool Installation Costs
There are a few different fiberglass pool packages to choose from, with the most expensive being a turn-key fiberglass pool installation costing $45,000 to $85,000. As you go lower in price, you’ll have to do more of the installation work involved yourself, but you can get a DIY or self-install package for as little as $12,000.
|DIY or Self-Install||$12,000 to $30,000||The fiberglass pool shell and kit is shipped and delivered.|
|Assisted Pool Installation
(Dig, Set, Fill)
|$20,000 to $45,000||Permits are taken care of, the hole is dug, the shell is installed, backfill is packed around it, and it’s filled with water.|
|Standard Pool Installation||$30,000 to $65,000||As well as the steps above, you get decking, pool cleaning, and grading.|
|Turn-Key Pool Installation||$45,000 to $85,000||This includes a pool enclosure or fence and electrical work.|
You can choose the level of service you want and pay a higher pool installation cost at each level. Labor costs for fiberglass pool installation account for about 25% of the price.
DIY or Self-Install
DIY fiberglass pool kits cost $18,000 on average, and you could save about 25% by installing your fiberglass inground pool yourself. However, this is only the base price, and you need to keep in mind the time involved and additional costs.
|Fiberglass Pool Shell||$9,000 – $24,000|
|Equipment Rental||$1,800 – $2,500|
|Crane||$400 – $800|
|Water (Trucked In)||$700 – $1,200|
|Backfill Material||$1,000 – $2,000|
|Plumbing||$300 – $600|
|Pool Equipment||$700 – $1,200|
Fiberglass Pool Shell Prices
The average cost of a fiberglass pool shell is $13,000 for a 14' x 28' pool but can range from $9,000 to $24,000 depending on the size, and delivery costs between $600 and $2,500.
|Shell Size||Average Prices|
|Small – 27’ or less||$9,000 – $13,000|
|Medium – 28’ to 34’||$12,000 – $16,000|
|Large – 35’ or more||$16,000 – $24,000|
After the cost for the fiberglass shell, you’ll need to pay for the excavated hole it will be dropped into, along with your backfill, plumbing fittings and pipes, and pool pump.
This cost also covers the depth of the pool at an average of 5.5’ to 6.5’ deep, but doesn’t account for any of the additional aspects most homeowners enjoy adding to their inground pools, such as decking and lighting. Don’t forget the cost of filling the pool with water as well.

Fiberglass Pool Costs Vs. Other Pool Types
Your fiberglass pool will be about 10% cheaper than a concrete or gunite pool but about 20% more expensive than a vinyl pool. However, over ten years of upkeep costs, fiberglass is the clear winner, costing 50% less to maintain than a vinyl pool and 75% less than a concrete pool.
|Material||Cost To Install||Yearly Maintenance||Lasts|
|Fiberglass||$18,000 – $65,000||$375+||25+ years|
|Concrete||$29,000 – $60,000||$2,750+||50+ years|
|Vinyl||$25,000 – $45,000||$1,325+||Replace liner every 10 years|
Vinyl Liner Inground Pools
Vinyl inground pools cost $25,000 to $45,000, and are available in a range of designs and styles. However, the yearly maintenance is about $1,325 and the liner will need replacing every 10 years.
A new pool liner costs $3,000+ to install or replace.
Concrete or Gunite Inground Pools
Concrete pools cost $29,000 and $60,000 but typically need to be replastered every 8 to 12 years for $6,000 to $10,000.
Concrete pools require high chemical use and acid-washing.
The 10-year cost of ownership to maintain a concrete pool averages $27,500.
Above Ground Pools
The average cost of an above ground swimming pool kit is $2,000 to $5,000 depending on the brand, size, and quality of the pool. Hiring a professional to install the kit adds $1,000 to $3,000. The average above ground pool will only last for 7 to 15 years before needing to be replaced, whereas the liner will likely need to be replaced every 6 years.
Fiberglass Pools Pros and Cons
Fiberglass pools present many benefits compared to other pool materials.
Advantages of Fiberglass Pools
Fiberglass pools are low maintenance and around 20% cheaper than concrete pools.
Fiberglass shells can be designed and created in any shape or size you want.
The fiberglass shell comes delivered as a single unit that will be dropped into place.
The time from ordering to swimming is much shorter than that of a traditional pool installation. In some cases, this could be less than a week, including digging out the ground and the electrical work.
Because of the gel coat finish, not only will it last until your kids have left the house, but it needs almost zero maintenance, looks lovely, and has a really smooth surface. You’ll never need to replace a liner or resurface it. It’s also the best type to stand up to dogs’ nails.
The smooth surface is super resistant to algae and requires low maintenance of pH levels. It’s also smooth underfoot rather than abrasive.
You can use fiberglass pools with salt-purification systems to create a saltwater pool.
Maintenance costs are very low—$4,000 versus $27,400 for a concrete pool over a 10-year period.
Disadvantages of Fiberglass Pools
Because of transportation and the installation process, a fiberglass pool will generally not come any larger than 16' wide. However, being molded at the factory, it still manages to be a significant length.
The extent of customization, as well as the range of sizes, is minimal if you choose from prefab pools in stock.
If the backfill is not correctly packed in around the pool shell, the shell may bend, affecting plumbing pipes and drains.
Fiberglass Pool Cost Factors
Size of Pool Shell
The size of your fiberglass shell is one of the most significant upfront costs.
|Shell size||Average price|
|Small||$9,000 – $13,000|
|Medium||$12,000 – $16,000|
|Large||$16,000 – $24,000|
Delivery fees range from $600 to $2,500. Some inground pool shell kits include the cost of the shell, permits, and setting the pool in place—straight and level, while others include decking and a fence.
Another major cost factor is the excavation. Removing the dirt alone for a 14’ x 28’ pool costs about $12,825, which includes the dirt being disposed of properly.
Hiring an electrician costs $50 to $130 per hour to bring power to your pool pump and the pool filter. If you have a water heater, the wiring may require upgrading the breaker panel capacity and changing the meter base.
A pool heat pump costs $2,000 to $6,000 installed. The colder the climate you live in, the more power your heater will require, hence the higher cost in more northern climates.
The cost to build a deck or patio around your inground pool is $3,000 to $10,000. Most installation packages include a concrete deck, but you can choose the look of the concrete.
Stamped concrete costs $6,000 to $20,000, about double the cost of original concrete, and comes in practically any pattern, color, or texture.
Pool fencing costs $400 to $4,400 depending on which material you choose and how long and tall the fence will be. You can have a 6-foot aluminum pool fence installed for $4.40 to $5.55 per linear foot or approximately $450 for a 15’ x 30’ pool. Add a gate with a latch for an additional $200 to $250 installed.
Aluminum fencing is the most popular material for pool fences or enclosures as it’s economical and comes in a variety of colors.
Swimming pool permits costing $50 to $200 are required to ensure the installation meets all local building codes for water sources, plumbing plans, and closeness to water and wastewater easements, septic systems, protected trees, and erosion hazard zones. The inground pool also can’t go over your impervious ground cover limits for your property or be an obnoxious sight to your neighbors.
Common Mistakes To Avoid
Choosing the Wrong Size and Depth – Decide what you want the pool for before you add on all the possible features available. You won’t be happy with a family pool, deep end, and diving board if you only want to do laps.
Poor Pool Maintenance – Choose your maintenance plan and expenses in advance.
Picking the Cheapest Options – Uninsured or unbonded pool installers might save you thousands up front but cost you much more than that when the pool starts showing problems from a bad installation job. Check online ratings for contractors on any bids you get, and ask to see their insurance certificate.
Buying a Pool with No Warranty on Labor or Parts – You’ll have no way to get any repair or replacement costs covered if something wasn’t installed properly.
Inexperienced DIY Work - You can avoid the angst of having an off-kilter pool if you level the ground properly to begin with, and keep it perfectly straight while adding backfill.
