Intro:

The cost to install a fiberglass pool in Phoenix, AZ is $34,368 on average, with most projects totaling between $25,892 and $50,612 depending on the pool type and size. Phoenix, AZ, is the hottest city in the U.S., so installing a pool here is a worthwhile investment. Fiberglass is a particularly popular option thanks to its low-maintenance design and resistance to cracking in the high heat and harsh sunlight.

Fiberglass Pool Installation Cost Factors

Fiberglass pool installation costs in Phoenix, AZ vary based primarily on the type of pool, namely, in-ground versus above-ground, and the size of the pool. Specific material types and amounts will also influence the project total.

Installation Costs by Pool Type

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 $20,000 to $75,000.

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 excavation costs make them more expensive to install, so expect to pay $40,000 to $100,000.

Lap Pool

The average cost of a fiberglass lap pool is $30,000 to $65,000. 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 $20,000 and $60,000. These pools rely on salt instead of chlorine to keep the water clean. This type of pool works particularly well with 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 $40,000 to $70,000 to install this elegant type of pool.

Zero-Entry

Expect to pay $30,000 to $75,000 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 $15,000 to $40,000. 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 $800 per linear foot for the materials, or about $1,200 per linear foot with labor included.

Materials

Fiberglass pool materials cost around $5,000 to $55,000 for materials. Fiberglass pool shells cost $4,500 to $30,000, and the pump and filtration system costs $1,200 to $4,500. For backfill, gravel will cost about $1 to $3 per square foot. You will also need water, of course, which costs about $60 to $120 for a standard 15,000- to 30,000-gallon swimming pool.

Pool Installation Pro Costs

Installing a fiberglass pool should always be left to the pros. Not only is this a massive undertaking that involves leveling or excavating your backyard, driving heavy machinery, and ensuring the project meets strict building codes. The best person to hire for this job: a swimming pool pro in Phoenix, AZ, who knows exactly how to build a fiberglass pool that will last in the desert heat and will abide by the city’s specific requirements for pools.

Labor

Labor makes up around 50% of the cost to install a pool, because this is a difficult project that involves specialized skills and knowledge to complete. Although you’ll typically see a per linear foot, per square foot, or total project charge, the labor cost breaks down to around $55 to $150 per hour, per worker, and usually involves at least five workers for 160 hours.

Permits

Installing a swimming pool requires a permit from the Phoenix, AZ, Planning and Development department. Swimming pools have a minimum permit fee of $180, but you could pay more when factoring in additional work, such as installing plumbing or electrical lines.

Insurance

Adding a swimming pool to your home can increase the home’s value while also presenting a risk of liability, both of which can lead to higher premiums on your homeowners' insurance. Ultimately, Arizona homeowners pay about $50 to $75 more per year when adding a pool, but the exact increase will vary based on your policy and coverage.

Additional Pros to Consider Hiring

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.
