How Much Does an Inground Pool Cost in St. George, Utah?

Southern Utah has its own kind of magic—towering red rocks, desert sun, and a backyard that practically begs for a pool. And in St. George, where triple-digit temps aren't just a summer thing, adding an inground pool isn’t just a luxury—it’s a lifestyle upgrade.

But if you're thinking about taking the plunge, you’ve probably got some questions swirling in your head, like:

• How much will a pool cost in Southern Utah?

• Which type of pool makes the most sense for my backyard and climate?

• What does long-term maintenance really look like out here?

We’re going to break all that down. As a fiberglass pool manufacturer, we field questions from all over the country—including right here in Utah. And while we don’t install pools ourselves, we work with local professionals who do—like the team at River Pools Southern Utah.

Let’s get into it.

Who Installs Inground Pools in St. George, Utah?

Before we talk numbers, here’s a quick but important clarification...

River Pools designs and manufactures fiberglass pool shells. These are made in the U.S. and shipped to homeowners across the country. But the installation is always done by independent local companies, such as River Pools® Southern Utah.

So when we reference "installation pricing," we’re sharing estimates based on typical projects completed by independent installation companies—not a service we provide as the manufacturer.

How Much Does It Really Cost to Install a Pool in St. George?

Let’s talk ballpark figures.

In Southern Utah, you can expect to spend anywhere from $45,000 to over $200,000 for a complete inground pool project. That range depends on:

• Pool type and material

• Size and shape

• Features (tanning ledge, spa, waterfall, etc.)

• Backyard conditions (sloped yard, access, retaining walls)

• Landscaping, fencing, and decking

Here’s how it breaks down by pool type:

Vinyl Liner Pools

• Installation Cost: $45,000–$80,000+ (base packages), $75,000-100,000+ (turn-key packages)

• Why People Choose It: Lower upfront cost, flexible designs

• But: Liners typically need to be replaced every 5–9 years, which adds up

Southern Utah Tip: Dry heat and sharp rocks can accelerate wear on vinyl liners. That makes maintenance a little more frequent in this part of the country.

Concrete (Gunite) Pools

• Installation Cost: $95,000–$225,000+

• Why People Choose It: Fully customizable shape and size

• But: Most expensive to build and maintain

Fun fact: Concrete pools typically need more chemicals and energy to keep the water clean, especially in hot, sunny climates like southern Utah.

Fiberglass Pools

• Installation Cost: $70,000–$100,000, $150,000+ for more complex builds 

• Why People Choose It: Fast installation, low maintenance, smooth finish, great durability

• But: You’re limited to pre-designed shapes (though there are tons to choose from)

Local Insight: We’ve seen many fiberglass pool projects in St. George come in right around $90K, including popular upgrades like LED lights and water features.

Which Pool Type Is Best for St. George?
