Fiberglass Pool Cost

The cost to install a fiberglass pool ranges between $5,000 and $40,000, with most homeowners spending between $20,000 and $35,000. While this is less than the cost to put in a cement pool, the price is still significant. The final cost for a fiberglass pool project depends on a variety of factors.

Fiberglass Pool Cost Factors

The costs for a basic installation of a fiberglass pool include the following:

  • Excavation and backfill
  • The pool shell and filter pump
  • Any shipping charges
  • Installation of the pool
  • Filling the pool with water

Multiple factors affect costs for fiberglass pool installation. These include the size of the pool, removal of trees or bushes during site prep, and fees for city or country permits. Typically, it takes a five-man crew to install a pool, and labor costs are often determined by the pool size. Standard pricing runs about $5.50/sf.

Fiberglass Pools Cost Vs. Other Types

While fiberglass pools are more expensive than above-ground pools, they fall in the middle of the cost range when compared to other inground pools. A vinyl-liner pool is typically less expensive than a fiberglass pool, but because the liner may need to be changed several times, it may cost more in the long run. The table below shows the comparative prices of various pool types:

Type of Pool

Average Price Range

Above Ground Pool

$1,500 to $5,000

Inground Vinyl-Liner Pool

$10,000 to $25,000

Inground Fiberglass Pool

$5,000 to $40,000

Inground Concrete (Or Gunite) Pool

$17,000 to $45,000

Because fiberglass pools come in a wide array of designs, certain shapes may be more expensive than others. When considering the installation of a fiberglass pool, you should be aware of a few additional cost considerations.

Other Cost Considerations

Extra accessories help personalize a backyard pool and make it more enjoyable. Items that add to the price of a fiberglass pool include:

  • Heat Pumps
  • Pool Vacuums
  • Diving Boards
  • Pool Slides
  • Ladders And Handrails
  • Pool Covers
  • Pool Lighting
  • Pool Enclosures
  • Pool Toys

When putting in a pool, you should also prepare for maintenance and repair costs as well as higher property taxes and insurance. Your county tax officials and an insurance agent can provide estimates for these additional costs.

Fiberglass Pool Maintenance

Advantages Of Fiberglass Pools

A fiberglass pool offers a number of advantages over other types of pools. It doesn't require liner replacements like vinyl-liner pools, and unlike concrete pools, it never needs resurfacing. Fiberglass pools are sturdy yet flexible, and repairs are easily made onsite. Because fiberglass isn't very porous, it’s resistant to algae growth, which equates to easy vacuuming and cleaning. Fiberglass also doesn't corrode, so it's the perfect pool material for salt-purification systems. Because these pools have smooth, non-abrasive shells, they offer a comfortable surface for bare feet. Finally, no other type of outdoor swimming pool offers as many design options. Round, square, oblong, oval or asymmetrical — there's a fiberglass pool for almost every outdoor space.

Disadvantages Of Fiberglass Pools

Although fiberglass pools offer a host of advantages, they do come with a few disadvantages. When the backfill material doesn't properly support a fiberglass shell, it can be vulnerable to bending, bulging, and warping. Sometimes, the sand supporting a fiberglass shell settles and shifts, which can affect the plumbing lines and cause leaks. Settling sand can also cause cracks in the main drains at the bottom of the pool. Unlike a concrete pool, fiberglass models are not easy to customize, and you're limited to the specific molds offered by your manufacturer. One disadvantage of all in-ground pools is that they require a cover or separate pool fencing for families with small children.

Advantages of Fiberglass Pools

Fiberglass Pool Maintenance

Most professional pool maintenance services cost from $75 to $100 per hour. DIY pool maintenance costs roughly $175 per month on average for supplies and chemicals. Gain a better understanding of pool maintenance items below:


To clean leaves and other debris from the surface of the water, use a skimming net attached to a telescoping pole. A pool vacuum helps remove dirt and other debris from the pool floor. For a deeper cleaning of the pool walls and floor, use a soft-bristle brush or sponge and cleaners formulated specifically for fiberglass surfaces.


Fiberglass shells occasionally stain if levels of metal in the water are too high. Too much iron can cause rust-colored stains, and excessive copper can stain the shell a blue-green color. Applying a metal-chelating agent every few weeks can help balance metal levels and keep fiberglass pool shells stain-free. Follow the manufacturer's instructions for proper usage.

Chemical Balance

Proper chemical balance is vital for safe and enjoyable swimming, and you should test the water daily during the swimming season. Aim for the numbers below for a safe balance:

  • pH levels between 7.4 and 7.6
  • Chlorine levels between 1.0 and 3.0 ppm
  • Total alkalinity between 80 and 140 ppm

Turning on the pool filter after each use helps keep the pool clean and the chemicals balanced. Let the filter run for six to eight hours for adequate water circulation.


Over 10 to 15 years, fiberglass can lose its shine. With special buffing equipment, professionals polish a fiberglass pool shell to its original luster.

Pool Cover

Pool covers help keep out dirt and debris for less pool maintenance. Retractable models make covering and uncovering a pool quick and easy, and solar covers help keep water warm on cooler days.

Fiberglass Pool Shapes, Construction & Design

Pools made of fiberglass are pre-formed and sit in the ground on top of a layer of gravel. These pools come in a wide variety of shapes and sizes for almost any kind of yard or outdoor space. While some are surrounded by brick or concrete, others feature wooden deck borders. Non-slip steps make fiberglass swimming pools safe, and these can be incorporated during installation. To make your outdoor space more stylish and comfortable, add a complimentary hot tub, fountain, or waterfall around the pool, along with lounge chairs and umbrellas.
