How Much Does it Cost to Install a Fiberglass Pool in Washington, D.C.? [2026 Data]

Washington, D.C.’s higher cost of living drives fiberglass pool installation costs above the national average. The cost to install a fiberglass pool in Washington, D.C., ranges between $27,296 and $53,356, with most homeowners paying around $36,231, depending on factors like pool size, material choices, and site accessibility. Here’s what to expect when budgeting for a fiberglass pool in the nation’s capital.

Fiberglass Pool Installation Cost Factors

Below are the main factors that will play into your cost to install a fiberglass pool in Washington, D.C.

Installation Costs by Pool Type

Whether you’re considering an above-ground pool or an in-ground pool, there is a fiberglass pool design to fit most preferences and needs, so let’s review how much homeowners can expect to spend for each type.

Above-Ground

Fiberglass pools installed at least partially above ground need additional support so that they stay level and do not crack over time. That is why they are installed with a structure around the shell, resulting in the entire project costing $21,800 to $81,700.

In-ground

In-ground fiberglass pools are installed below ground level. They are a prefabricated, one-piece fiberglass shell that a local inground pool contractor places into a pre-dug hole. Like all fiberglass pools, they have a smooth gel coat finish and are installed quickly. However, the added pool excavation costs make them more expensive to install, so expect to pay $43,600 to $108,900.

Lap Pool

The average cost of a fiberglass lap pool is $32,700 to $70,800. Lap pools are long and rectangular, best used for swimming laps. Since they usually measure 40 feet by eight feet, their narrow design makes them a great candidate for small properties.

Saltwater Pool

To install a fiberglass saltwater pool, you can expect to pay between $21,800 to $65,300. These pools rely on salt instead of chlorine to keep the water clean. Comparing a saltwater versus chlorine pool, saltwater pools are the optimal choice for fiberglass because salt will not damage the material.

Infinity Pool

Swimming pool shapes other than the usual rectangular one will cost more. An infinity pool is a pool with an exposed side that gives the illusion of extending toward the horizon, ocean, or backyard. It will cost an average of $43,600 to $76,200 to install this elegant type of pool.

Zero-Entry

Expect to pay $32,700 to $81,700 for a zero-entry pool. This convenient type of pool, which allows you to walk in from the shallowest side or the deepest end, no climbing ladders or steps required.

Plunge Pool

The average cost for a fiberglass plunge pool is $16,300 to $43,600. While plunge pools are not made for swimming, their small size—six by 12 feet wide, and just four to six feet deep—makes them perfect for small properties and quick dips to cool off in warmer months.

Size

Fiberglass pool installation costs about $870 per linear foot for materials, or about $1,310 per linear foot with labor included.

Materials

Fiberglass pool materials cost around $5,400 to $59,900. Fiberglass pool shells cost $4,900 to $32,700, and the pump and filtration system costs $1,310 to $4,900. For backfill, gravel will cost about $1 to $3 per square foot. You will also need water, which costs about $65 to $130 for a standard 15,000- to 30,000-gallon swimming pool.

Pool Installation Pro Costs

These are the key factors that will impact the labor charges for building a fiberglass pool in Washington, D.C.

Local Labor Rates

Labor is one of the biggest cost factors of pool installation, accounting for around 25% to 50% of the total expense. Hourly rates for pool builders in Washington, D.C., can range from $55 to $150, so make sure your quote includes labor and explains how those costs are calculated.

Permits

In Washington, D.C., you’ll need a swimming pool permit to build a pool, along with possible separate permits for water system work. A local contractor will know how to secure the proper approvals and schedule inspections.

Taxes and Insurance

Installing a fiberglass pool in Washington, D.C. can increase both your property taxes and homeowners' insurance costs. This is because it can potentially raise your home’s assessed value, increasing your yearly tax liability, and the added liability concern will increase your insurance premium.

Additional Pros to Consider Hiring

You may need to bring in additional professionals during your fiberglass pool installation. For instance, installing lighting or a pool heater typically requires a licensed electrician, while a landscaper can help spruce up the space and create an outdoor oasis. Here are some typical costs:

• Electrician cost: $50–$150 per hour

• Plumber cost: $45–$200 per hour

• Landscaper cost: $50–$100 per hour

• Pool maintenance contractor cost: $50–$300 per month

Does Installing a Fiberglass Pool Increase Home Value?

On a national level, the ROI of installing a pool varies anywhere from 5% to 56%, with location playing a key role in potential returns. In Washington, D.C., outdoor improvements often deliver a moderate to high ROI, driven by the city’s hot, humid summers and emphasis on outdoor entertaining.

In-ground fiberglass pools typically provide better returns than above-ground alternatives, especially when paired with high-end finishes or integrated landscaping. Still, pools are a polarizing asset for buyers, so the perceived value is ultimately up to individual preferences.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
