What Does Building a Pool Cost?
Building an in-ground pool with an attached spa typically costs between $55,000 and $130,000 or more, with an average around $85,000. Where you land depends mostly on the pool type, vinyl-liner, fiberglass, or gunite (concrete), plus the size, features, and site conditions. This is a major, long-term home investment, and understanding the ranges helps you plan realistically. The ranges below are for the pool itself; a spa built at the same time as the pool typically adds $10,000 to $15,000. Here’s how the cost breaks down by pool type.
Vinyl-Liner Pool: $35,000 to $80,000
A vinyl-liner pool is the most affordable in-ground option, running about $35,000 to $80,000. It’s built with a steel or polymer wall frame and a custom vinyl liner that holds the water, over a sand or grout base. Vinyl pools have a lower upfront cost and a smooth, comfortable surface, but the liner needs replacing periodically (typically every several years to a decade or so), which is a recurring future cost to factor in. They offer flexibility in shape and are a popular choice for homeowners wanting an in-ground pool without the top-tier price. The liner replacement cycle is the main long-term consideration.

Fiberglass Pool: $60,000 to $110,000
A fiberglass pool runs about $60,000 to $110,000. It’s a pre-manufactured shell, molded off-site and lowered into the excavated hole in one piece, which means a much faster installation than other types, often days rather than weeks for the shell itself. Fiberglass has a smooth, non-porous surface that resists algae and requires less chemical use and maintenance over time. The trade-off is that shapes and sizes are limited to the manufactured molds, and the shell must fit down your access route. For homeowners wanting low maintenance and quick installation, fiberglass is an appealing middle option. (For more on this, see What Makes Pool Construction Cost More (or Less)?.)
Gunite/Concrete Custom Pool: $65,000 to $120,000+
A gunite or concrete pool is the premium, fully custom option, running $65,000 to $120,000 or more. Gunite is sprayed over a steel rebar framework and finished with plaster, aggregate, or tile, allowing virtually any shape, size, depth, and feature. This is the choice for custom designs, integrated spas, vanishing edges, tanning ledges, and elaborate water features. Gunite pools are the most durable and customizable, but they cost the most, take the longest to build (often the full one-to-three-month range), and need periodic resurfacing over their life. For a truly bespoke pool, gunite is the top tier. (For more on this, see Vinyl vs. Fiberglass vs. Gunite: Which Pool Type Is Right?.)
What Else Drives the Cost
Beyond the pool type, cost depends heavily on size, depth, and features, an integrated spa, heating, automation, lighting, water features, decking, and premium finishes all add substantially. Site conditions matter too: difficult access, rocky soil, a high water table, sloped terrain, or extensive excavation and grading raise the price. Decking, fencing (often required by code), and landscaping around the pool are frequently separate line items that add tens of thousands to the total project. The finished, landscaped pool often costs well beyond the pool shell alone.
Why Quotes Vary So Widely and What “Turnkey” Really Means
One of the most confusing things for homeowners pricing a pool is how enormously quotes can vary for what seems like the same project, and the usual reason isn’t that one builder is simply gouging. It’s that quotes often cover very different scopes. One builder’s number may be the pool shell and basic equipment only, while another’s includes decking, fencing, and landscaping, so a lower headline price can actually be the more expensive project once you add everything the first quote left out. The word to listen for is “turnkey,” meaning a complete, ready-to-use pool with all surrounding work included, versus a shell-only price that leaves the rest to you or other contractors.
To compare fairly, you have to normalize the scope: get each builder to itemize exactly what’s in and out, then add the missing pieces to the incomplete quotes so you’re comparing complete, finished-backyard totals. Site conditions add another layer of variability, since a builder who’s inspected your yard and factored in difficult access or excavation will quote higher, and more honestly, than one who hasn’t. The cheapest number is frequently the least complete or the least realistic about your site, which is why detailed, itemized, turnkey quotes from builders who’ve actually seen your property are the only ones worth comparing directly.
Getting an Accurate Price
Because pool construction spans an affordable vinyl pool to a six-figure custom gunite installation, an accurate price depends on the pool type, size, features, and your specific site. A modest vinyl pool on an easy site sits at the low end; a large custom gunite pool with a spa, features, and full decking runs well above $150,000. Because this is a major investment, get detailed quotes from multiple builders. When you’re ready, connect with a local pro below.

Frequently Asked Questions
An in-ground pool typically costs $55,000 to $130,000 or more, averaging around $85,000. A vinyl-liner pool runs $35,000 to $80,000, a fiberglass pool $60,000 to $110,000, and a custom gunite (concrete) pool $65,000 to $120,000+. Size, features, and site conditions move the number within those ranges.
A vinyl-liner pool, at about $35,000 to $80,000, is the most affordable in-ground option. It uses a wall frame and a custom liner that holds the water. The trade-off is that the liner needs periodic replacement (typically every several years to a decade or so), a recurring future cost to factor into ownership.
About $60,000 to $110,000. A fiberglass pool is a pre-manufactured shell lowered into the hole in one piece, giving a much faster installation and a smooth, non-porous surface that resists algae and needs less maintenance. The trade-off is that shapes and sizes are limited to manufactured molds that must fit your access route.
Because gunite (concrete) pools are fully custom, sprayed over steel rebar and finished with plaster, aggregate, or tile, allowing any shape, size, depth, and feature. At $65,000 to $120,000+, they're the most durable and customizable but take the longest to build and need periodic resurfacing. They're the premium, bespoke option.

Decking, code-required fencing, and landscaping are often separate line items that add tens of thousands, so the finished pool costs well beyond the shell alone.
