How Much Does an Inground Pool Cost? 4 Factors and 2026 Pricing
An inground pool costs $25,000 to $120,000+ depending on material, pool size, and finish, with most homeowners paying $50,000 to $100,000 for a turn-key installation. Vinyl liner pools sit at the low end of the price range, fiberglass pools run mid-range, and gunite or concrete pools carry the highest base price. Add-ons like pool decking, fencing, landscaping, and a pool heater can push the total another $25,000 to $50,000 on a backyard retreat project.
If you're budgeting for a new inground swimming pool, you've probably noticed the numbers are all over the place. One pool builder quotes $45,000, the next wants $110,000 for what sounds like the same project. The gap isn't marketing fluff. It reflects real differences in pool type, excavation, site conditions, permits, and design complexity.
This guide walks homeowners through what drives inground pool pricing in 2026, breaks costs out by material (fiberglass, vinyl liner, gunite), shows how pool size shifts the budget, and names the hidden extras most first-time buyers miss. We build pools in Southern California at Adams Pool & Spa, so we've included a Long Beach regional example near the bottom if you're shopping in this market.

How Much Does an Inground Pool Cost?
Most homeowners spend $50,000 to $100,000 on an inground pool installation, with a national average near $66,000. Vinyl liner pools start around $25,000, fiberglass pools run $30,000 to $85,000, and gunite or concrete pools range from $50,000 to $120,000+ for a turn-key project including basic decking.
That's the short answer. The real answer depends on five variables we'll cover below: material, size, region, finish, and extras.
Inground Pool Cost by Type: Fiberglass vs Vinyl Liner vs Gunite
Vinyl liner pools are the cheapest inground option upfront. Expect $25,000 to $65,000 for a full install, with the low end covering a basic rectangular pool and the high end covering a larger or custom shape. The pool shell is a steel or polymer wall panel system with a vinyl liner stretched across it.
The catch: the liner itself needs to be replaced every 8 to 12 years at $5,000 to $7,000 per replacement. That's a real ownership cost most sales brochures skip. Over 30 years, vinyl liner pools can actually cost more than fiberglass.
Fiberglass pools run $30,000 to $85,000 for most residential projects, though premium turn-key packages can push $100,000+. The shell arrives at your house as a single pre-molded piece, drops into the hole in a day, and typically finishes in 3 to 6 weeks total.
Per NerdWallet's 2026 pool cost research, fiberglass is the fastest inground option to install. The tradeoff is shape and size limits. You pick from the manufacturer's catalog, and anything larger than about 16 x 40 ft gets expensive to ship.
Gunite pools (sometimes called concrete or shotcrete pools) are the most expensive and the most flexible. Base price runs $50,000 to $120,000, and fully loaded custom builds with spas, tanning ledges, and water features can push $200,000+.
Gunite is the only pool type with zero design constraints. Any shape, any depth, any finish. It's the category we specialize in at Adams Pool & Spa for clients who want a true custom swimming pool design. The tradeoff is build time (3 to 6 months is normal) and a roughly 10-year resurfacing cycle.
Inground Pool Cost by Size
Pool size is the second biggest price driver after material. Here's a snapshot of what gunite/concrete inground pools run by common dimension, based on a $50 to $125 per square foot national range.
| Pool Size | Square Footage | Typical Cost Range |
|---|---|---|
| 10 x 20 ft (small plunge) | 200 sq ft | $10,000 – $25,000 |
| 14 x 28 ft (small family) | 392 sq ft | $19,600 – $49,000 |
| 16 x 32 ft (standard family) | 512 sq ft | $25,600 – $64,000 |
| 20 x 40 ft (large / lap pool) | 800 sq ft | $40,000 – $100,000 |
These are shell-only numbers for the pool itself. They don't include decking, fencing, landscaping, or equipment upgrades. A full turn-key backyard retreat with a 16 x 32 ft gunite pool usually lands between $75,000 and $120,000 once you add the extras.
What Factors Affect Inground Pool Pricing?
Five factors move your pool quote up or down:
Additional Costs Beyond the Pool Shell
The pool shell is only half the project. Here's what the other half usually runs:
How Much Does It Cost to Maintain an Inground Pool?
Annual ownership costs for a typical 16 x 32 ft inground pool in a warm climate:
Regional Pricing: Does Location Affect Pool Cost?
Yes, significantly. The same 15 x 30 ft base pool that costs roughly $50,000 in Phoenix or Tampa can hit $80,000 in Chicago or Boston. Two reasons: labor rates and build season. Colder markets have a 4 to 6 month build window and higher union labor costs, so contractors price projects higher.
Long Beach and Southern California Example
Southern California sits in the middle of the pricing map. Year-round build season keeps labor scheduling flexible, but California labor rates, permit requirements, and strict energy code (Title 24) push costs slightly above other warm markets.
A realistic Long Beach budget for a 16 x 32 ft gunite pool with standard plaster finish, basic decking, safety fence, and variable-speed pump runs roughly $85,000 to $130,000 turn-key. Add a spa, pebble finish, or water features and you're closer to $150,000 to $200,000.

Is an Inground Pool Worth the Investment?
Depends what you want out of it. As a pure financial return, pools don't pay for themselves. Most appraisers add $10,000 to $25,000 to home value for an inground pool in a warm market, which is a fraction of what you spend building it.
As a lifestyle investment, the math looks different. Families who use their pool 100+ days a year for swim season, kids' birthdays, and backyard staycations usually say it's the best money they've spent on the house. Homeowners who barely touch the water after year two often regret it.
Honest test: if you'd use a country club pool more than 20 times a year, you'll probably love owning one. If not, consider a smaller plunge pool or skip it entirely.
How to Save Money on Your Inground Pool Project
Five ways to cut pool costs without cutting corners:
Contractors get hungry in fall and winter. In Long Beach, November through February pricing is typically 5% to 10% lower than peak spring demand.
Custom shapes, tanning ledges, and vanishing edges add $10,000 to $40,000 fast. Rectangles are cheaper to build and easier to cover.
Build the pool and basic decking in year one. Add landscaping, heater, and automation in year two or three when budget allows.
You'll save $3,000 to $8,000 upfront and can upgrade during your first resurfacing cycle if you want a premium finish later.
Not contractors who subcontract. Ask for itemized quotes so you can compare apples to apples.
Frequently Asked Questions About Inground Pool Cost
How much does a 12x24 inground pool cost?
A small 12 x 24 ft inground pool runs roughly $20,000 to $45,000 for the shell, depending on material. Vinyl liner is cheapest at $20,000 to $30,000, fiberglass runs $25,000 to $40,000, and gunite lands at $30,000 to $45,000. Add decking, fencing, and equipment to get a realistic turn-key number 20% to 40% higher.
What's the cheapest type of inground pool?
Vinyl liner pools have the lowest upfront cost at $25,000 to $65,000. Over a 30-year ownership window, fiberglass often comes out cheapest because it has no liner replacement cycle and lower chemical usage. If you're optimizing for upfront budget, pick vinyl. If you're optimizing for lifetime cost, pick fiberglass.
How much does it cost to maintain an inground pool per year?
Expect $1,500 to $4,000 per year in combined costs for chemicals, electricity, minor repairs, and professional service (if you hire it out). DIY maintenance drops that to $800 to $1,800 per year, but you're trading money for 2 to 4 hours of weekly work.
Can I install an inground pool myself to save money?
Some fiberglass manufacturers sell DIY packages where the homeowner handles excavation and the manufacturer drops the shell. You can save $15,000 to $25,000 this way, but you take on permit liability, site prep, equipment setup, and mistakes that can cost more than you saved. For gunite, DIY isn't realistic.
How long does it take to build an inground pool?
Fiberglass: 3 to 6 weeks. Vinyl liner: 4 to 8 weeks. Gunite/concrete: 3 to 6 months from permit to first swim. Weather, permits, and backyard access all affect timelines. In Long Beach we typically quote 10 to 14 weeks for a standard gunite build.
Does a pool add value to my home?
Usually $10,000 to $25,000 in appraised value in warm-climate markets where pools are expected. In cold markets, pools can actually hurt resale by narrowing your buyer pool. Check comparable sales in your neighborhood before building if resale matters.

Terms behind every inground pool quote
Shell, finish, pump, and heater, the four cost drivers that decide every quote.
- Shotcrete
-
Concrete pneumatically projected at high velocity onto a steel rebar cage. Forms the structural shell of every gunite pool and is the construction method we use on new Long Beach builds.
- Plaster
-
The interior finish coat on a gunite pool, traditionally white marble plaster. Modern variants include color quartz and pebble aggregate. Lifespan is 8 to 15 years before replastering is needed.
- Variable-speed pump
-
A pool pump with a permanent-magnet motor that runs at adjustable speeds. Cuts pool electrical bills by 60 to 80 percent versus single-speed pumps and is required by California Title 24 on new builds.
- Heat pump
-
An electric pool heater that moves heat from the air into pool water. Lower operating cost than gas in mild Long Beach winters; longer warm-up time than gas.
