For an inground pool in 2026, expect roughly $25,000 to $65,000 for a vinyl liner pool, $35,000 to $120,000 for fiberglass, and $50,000 to $175,000+ for concrete (gunite). Vinyl wins on upfront price, fiberglass wins on speed and low maintenance, and concrete wins on shape and size freedom. The right choice comes down to your budget, your timeline, and how custom you want to go.

Those three ranges tell most of the story, but they hide some real tradeoffs. A cheap vinyl pool can quietly cost you a new liner every 7 to 10 years. A low-maintenance fiberglass shell can't be made any shape you want. And a stunning custom concrete pool can take half a year to build and costs the most to maintain. Below we break down each construction type so you can match it to your situation. For context, the national average inground build runs around $66,000, with most homeowners landing between $44,500 and $87,500.

The quick comparison: vinyl vs fiberglass vs concrete

Here is how the three pool types stack up on the factors that matter most. All figures are total installed cost in 2026 U.S. dollars, presented as ranges because every yard, region, and feature list is different.

Factor Vinyl Liner Fiberglass Concrete / Gunite
Total installed cost $25,000–$65,000 $35,000–$120,000 $50,000–$175,000+
Install time Fast (a few weeks) 1–3 weeks 3–6 months
Yearly upkeep ~$1,400 + ~$625/yr liner fund ~$950 (lowest) ~$2,400 (highest)
Big recurring cost Liner replacement every 7–10 yrs ($3,400–$6,800) None major Acid washing / resurfacing
Shape & size freedom Good (custom builds cost more) Limited to catalog shells; ~16 ft width ship limit Unlimited — any shape or size
Best for Budget-focused buyers Low-maintenance, set-it-and-forget-it owners Custom dream pools, large lots

Vinyl liner pools: the budget pick

A vinyl liner pool uses a steel or polymer wall frame fitted with a flexible vinyl liner that holds the water. It is the most affordable way to get an inground pool, typically landing between $25,000 and $65,000 installed. Builds go up fast, often in just a few weeks, and the smooth liner is gentle on feet and toys.

The catch is the liner itself. Vinyl liners wear out and must be replaced every 7 to 10 years, at a cost of $3,400 to $6,800 each time. Spread over a decade, that adds roughly $625 a year to your real cost of ownership, on top of about $1,400 a year in chemicals, power, and water. Liners are also more vulnerable to punctures from sharp toys, pets, or tree debris than a hard shell.

Vinyl handles different shapes reasonably well, but custom layouts push the price up. If you want a simple rectangle or oval and the lowest sticker price, vinyl is hard to beat.

Best for

Budget-conscious homeowners who want an inground pool now and don't mind planning for a liner swap down the road.

Fiberglass pools: fast and low-maintenance

A fiberglass pool is a single pre-molded shell, manufactured in a factory and dropped into your excavated yard in one piece. Because so much of the work happens off-site, installation is quick, usually 1 to 3 weeks, and total cost runs $35,000 to $120,000.

The standout advantage is maintenance. The shell's smooth gelcoat surface resists algae, so you use fewer chemicals and spend less on upkeep, roughly $950 a year, the lowest of the three types. There is no liner to replace and no resurfacing cycle, which makes fiberglass the most hands-off option over the long haul.

The trade-off is flexibility. Fiberglass pools come from a manufacturer's catalog of fixed shapes and sizes, so you can't fully customize the design. There's also a hard physical limit: shells wider than about 16 feet are extremely difficult to transport, because anything wider can't safely travel by road. That caps how big and how wide a fiberglass pool can be. If your dream pool is wider than 16 feet, you'll need to look at concrete instead.

Best for

Owners who prize low maintenance, a fast install, and predictable long-term costs, and who can find a catalog shell that fits their yard.

Concrete / gunite pools: the custom dream

Concrete pools (also called gunite or shotcrete) are built on-site by spraying concrete over a steel rebar frame, then finishing with plaster, pebble, or tile. This is the most customizable option on the market: any shape, any size, any depth, vanishing edges, tanning ledges, attached spas, you name it. That freedom comes at a price, $50,000 to $175,000+, and elaborate custom builds can climb past $200,000.

Concrete also takes the longest to build, typically 3 to 6 months, because the structure has to be formed, sprayed, cured, and finished in stages. And it carries the highest ongoing cost, around $2,400 a year. The porous plaster surface harbors algae, so you'll use more chemicals, and every 10 to 15 years the pool needs acid washing and eventually resurfacing.

None of that is a dealbreaker if you want a true custom pool. Concrete is the only type that can be whatever you imagine, and for a large lot or a signature backyard, it's often the only material that delivers.

Best for

Homeowners who want a fully custom design or an unusually large or deep pool, and who have the budget and patience for a longer build.

How shape and depth change the math

Construction type is the biggest cost lever, but shape and depth matter too, and they interact with the material you choose. Our calculator prices four shapes: rectangle, oval, kidney, and L-shape. Here's the key insight: shape barely affects fiberglass cost, because you're choosing a pre-made shell, but custom shapes add real money on concrete and, to a lesser degree, vinyl.

Depth follows a predictable pattern across all three types. A shallow play pool (a flat 3.5 to 4.5 ft) runs about 5% less than standard. A standard pool (3 ft sloping to 5 or 6 ft, no diving) is the baseline. Adding an 8 ft-plus deep end for diving adds about 20%, and a diving board can raise your insurance, since insurers treat it as an "attractive nuisance."

Don't forget decking and the extras

The shell is only part of the project. Decking is the band of patio that wraps your pool, and it's one of the biggest line items people overlook. A roughly 5 ft band, enough for a walkway plus a couple of loungers, is the typical default. Poured concrete slab is the cheapest surface at $6 to $15 per square foot, while stamped concrete ($12–$28), pavers ($15–$32), and natural stone or travertine ($15–$40) cost more. Our pool deck cost guide walks through how to estimate your deck area.

Common add-ons stack up quickly too: a heater runs about $5,200 to install (and ~$650/yr to run), basic automation is $2,500 to $5,000, and a saltwater system is about $2,000. Then there are site factors buyers forget: excavation ($1,000–$5,000), permits ($100–$1,000+), electrical ($2,000–$10,000), and tough expansive-clay soil, which can add $5,000 to $30,000+ on its own.

So which pool type should you choose?

There's no single "best" pool type, only the best fit for your priorities:

Keep in mind that warm southern markets (TX, FL, AZ, GA) tend to run cheaper, while colder northeastern markets cost more, so where you live shifts every number above. The fastest way to see what your specific pool would cost, across all three types, is to run your own numbers.
