Fiberglass Pool Installation Costs

In addition to budgeting for the shell itself, it's a good idea to budget for installation costs as well. Fiberglass pool installation costs usually range from $10,000 to $20,000.

These costs typically include:

Size

Bigger pools require more labor and materials to install, so you'll pay more to install a larger pool than you would a small pool.

Shipping

If you need any materials for your pool installation shipped to your home, these shipping costs will be factored into the overall installation price. Shipping costs vary significantly depending on the size and weight of the item.

Land Preparation or Excavation

Your installers may need to prepare or excavate the land before installing the pool. Extensive preparation and excavation can significantly increase costs.

Location

Labor rates vary by location, so it's a good idea to call around and ask for estimates from multiple companies. Additionally, if your pool installation site is in a hard-to-reach location or very far from the installers' headquarters, you might incur an additional location charge.

Permits

Permits to install a pool typically cost $100 to $300. If you're adding a patio or deck, expect to pay an additional $100 to $500 for permits.

Filter Pump

Filter pumps keep your pool clean and swimmable. Prices vary by size and features, so ask your pool installer to help you find a filter that fits your budget and needs.

Backfill

Backfilling fills any remaining gaps around your pool after installation. Depending on your landscape, backfill materials typically include sand, gravel, or dirt.

Water

Of course, after installing the pool, you probably want to swim in it. In that case, you'll need to fill it with water. Most pool installers will complete this step for you, and the cost is included in the overall installation price.

Additional Features and Add-Ons

To enhance your pool, consider popular add-ons like decking, lighting, fencing, and more. However, these features will increase your overall installation costs.

Decking

Pool decks cost between $1,000 and $12,000, depending on size and material. Smaller decks (300–600 sq. ft.) may start as low as $1,000, mid-sized decks (600–900 sq ft) typically range from $3,000 to $8,000, and wraparound decks over 900 sq. ft. can range from $7,000 to $12,000.

Lighting

Installing pool lights usually costs between $700 and $1,800. LED lights typically cost the most, while incandescent and fiber optic lights are usually the most affordable.

Heater

Installing a pool heater is a great way to extend your swimming season. Pool heaters generally cost between $2,100 and $4,500, depending on their size, quality, and features.

Fencing

Fencing is an important safety measure because it helps prevent unsupervised pets and kids from entering the pool area. It can also enhance the aesthetics of your pool.

Pool fencing costs range from $15 to $25 per linear foot, with typical total costs between $1,500 and $10,000.

Landscaping

Landscaping costs range from $4 to $12 per square foot, and overall project expenses typically range between $3,000 and $5,000, depending on the scope of work.

Enclosures

Pool enclosures can give you an indoor pool experience outside. Enclosures usually range from $6,300 to $20,000. The material you choose affects the cost, with vinyl enclosures being the most affordable and glass and wood enclosures costing the most.

Maintenance Costs

Maintaining a fiberglass pool typically costs between $600 and $1,200 annually, less than other pool types that cost $1,080 to $1,800 per year. Some installers offer maintenance programs starting at $15 per month. Regular maintenance helps you avoid bigger repair costs down the road.

DIY vs. Pro Pool Builder 

While installing a fiberglass pool yourself can save you $10,000 to $20,000 in installation costs, unless you have pool-building expertise or a DIY pool kit, you should hire a professional. Installing a fiberglass pool is an invasive and complicated project best suited for pros. Hiring a professional ensures your pool is installed correctly and meets all safety standards, giving you peace of mind and saving you time and potential additional costs in the long run.
