On average, a fiberglass pool costs around $45,000. That includes about $15,000 in labor and $30,000 in materials.

Fiberglass pool prices vary so much because of add-ons like a heat pump, security cover, or decking. Your location and the size and shape of your pool will also influence the overall budget.

The $15,000 to $75,000 price range depends on the size and shape you choose. It splits into materials at $5,000 to $55,000 and labor at $10,000 to $20,000. Materials include the shell, backfill, and necessary equipment like a filter, heat pump, and cooling pump.

A fiberglass pool shell costs between $4,500 and $30,000. The exact price depends on the configuration (shape and depth) and size. You may pay up to $50,000 for large, custom shapes and sizes more than 40 feet long.

You can save that budget by building a pool yourself, but it's a labor-intensive process that requires significant knowledge, expertise, and the right equipment. 

Fiberglass Pool Installation Cost

A pool company will charge between $10,000 and $20,000 for the installation. That price includes:

  • Shell
  • Shipping
  • Excavation
  • Filter pump
  • Backfill
  • Filling the pool

It does not include decking, fencing, and other optional add-ons like lighting, fountains, or an automatic cover.

Labor alone will be around $5.50 per square foot, or $1,500 total for about 275 square feet. Most companies base their quote on a 5-man crew at 160 labor hours, taking the size of the pool into account. Ask the installer whether labor costs are included in the quote.

Average Cost to Convert a Vinyl Liner Pool to Fiberglass

Expect to pay between $40,000 and $65,000 to replace a vinyl liner with fiberglass. That's more expensive than installing an inground pool from scratch in most cases. It's necessary if you want to improve on your vinyl option in the same space in your yard.

The reason for the greater expense is the increased workload. The price of removing the vinyl liner can range up to $2,000. Access to the installation site is typically more difficult. You might need to dig up more space for the stones to backfill around the new shell.
