Overview: Swimming Pool Builders
A pool builder digs the hole, builds the shell and hands you back a yard. Three kinds of shell dominate. Gunite is concrete sprayed over steel, shaped however you like and finished in plaster, pebble or tile. Fiberglass arrives as one molded piece and drops in quickly, which shortens the build but fixes the shape. A vinyl liner pool has a steel or polymer wall with a liner fitted inside, and that liner is a wear item you replace down the road.
Before the shape matters, the site sets the price. How does an excavator get into the yard. What comes out of the ground: rock, sand or heavy clay. How high the water table sits, since a high one changes the design and can lift an empty shell. Whether a slope needs a retaining wall, and where the utilities run.
A permit is required almost everywhere, with inspections along the way, and a barrier around the water is not negotiable. Fence height, self-closing and self-latching gates and alarms on the house doors that open onto the pool are written into local code. Build them into the plan rather than adding them after the fill.
Builders working in your area are listed under the state and city pages below.
Cost of Building a Swimming Pool
Choose the pool dimensions and construction type before comparing prices. The compact in-ground examples below cover core installation; the finished backyard budget also needs any separate electrical work, barriers, decking and site restoration.
| Service or scope | Planning range | What this covers |
|---|---|---|
| 12-by-24-ft concrete in-ground pool | $30,000–$80,000per compact pool, core installation | Build an approximately 12-by-24-ft concrete pool with a specified depth, basic finish and circulation equipment on a straightforward accessible site.Compare depth, finish and equipment as well as footprint. Difficult ground or a more complete backyard package can exceed this range.Included scope and possible extrasScope used for this estimate: Pool structure and agreed basic finish; Ordinary excavation and installation; Specified basic circulation equipment Outside this estimate: Separate electrical or utility upgrades; Safety barriers and covers unless listed; Decking and landscaping unless listed; Rock, groundwater, retaining walls and difficult access; Premium finishes, spa and water features |
| 12-by-24-ft fiberglass in-ground pool | $35,000–$75,000per compact pool, core installation | Install an approximately 12-by-24-ft fiberglass shell with ordinary excavation, backfill and specified basic circulation equipment.Use the exact shell model and dimensions. Ask for a complete project total that lists crane access, electrical work, decking and barriers.Included scope and possible extrasScope used for this estimate: Specified shell; Ordinary delivery, excavation and placement; Backfill and agreed basic circulation equipment Outside this estimate: Separate electrical or utility upgrades; Safety barriers and covers unless listed; Decking and landscaping unless listed; Special crane access, rock, groundwater or retaining walls |
| 12-by-24-ft vinyl-liner in-ground pool | $28,000–$45,000per compact pool, core installation | Build an approximately 12-by-24-ft vinyl-liner pool with specified walls, depth, liner and basic circulation equipment on an accessible site.Compare liner thickness, steps, equipment and warranty. The quoted pool package may exclude items needed to complete the backyard.Included scope and possible extrasScope used for this estimate: Specified walls, base and liner; Ordinary excavation and installation; Specified basic circulation equipment Outside this estimate: Separate electrical or utility upgrades; Safety barriers and covers unless listed; Decking and landscaping unless listed; Rock, groundwater, retaining walls and difficult access; Heater and premium equipment unless listed |
| Above-ground pool installation | $2,000–$8,000per standard above-ground pool installation | Install a specified residential hard-sided above-ground pool on an agreed suitable base.Confirm the pool size, base preparation, assembly and equipment. Major leveling, electrical work, a deck and barriers are separate.Included scope and possible extrasScope used for this estimate: Specified pool kit and standard filtration; Agreed assembly and setup Outside this estimate: Deck construction; New electrical supply and barriers; Major grading |
| Broom-finished pool deck | $6–$12per sq ft of installed pool deck | Install a measured plain concrete pool deck with the thickness, base, slope, joints and finish specified for poolside use.Multiply the measured deck area by the rate, then check minimum charges, drainage, demolition and difficult access.Included scope and possible extrasScope used for this estimate: Specified base and slab; Planned joints; Broom finish Outside this estimate: Old-deck removal; Pool repairs; Decorative finish upgrades |
What changes the price
- Pool dimensions, depth, structure and equipment
- Access, soil, rock and groundwater conditions
- Decking, barriers, utilities and site restoration
Ask before you book
- What is the complete price to finish and use this pool, and which required items remain outside the contract?The shell package may exclude electrical work, barriers, permits, water, decking or restoration.
- Are dimensions, depth, equipment models and deck area identical in each quote?A low price can reflect a smaller pool or a more limited equipment and site-work allowance.
- How are rock, groundwater, soil removal and access problems priced and approved?Site conditions can change the budget substantially after excavation starts.
Check the scope
These are planning ranges for the stated pool scopes, not a finished-backyard guarantee. Confirm local barrier requirements and obtain an itemized total for all work needed to use the pool.
Compare quotes wisely
Choose the pool size and essential equipment first, then request optional pricing for premium finishes, heating and decorative decking.
How to read these estimates
These ranges combine published U.S. prices and cost guidance for the stated work. They are budgeting estimates, not offers from listed companies or a statistical national average. Confirm the total, included work and additional charges in writing.

Frequently asked questions
Gunite, fiberglass or a vinyl liner?
Gunite takes any shape and any depth and lasts the longest, but the build is the longest too and the interior finish is renewed eventually. Fiberglass is quick to install and easy on the surface, limited to the shapes the factory molds, and it has to fit through the access to your yard. A vinyl liner pool costs the least up front and the liner is a replacement item you plan for.
What permits does a new pool need?
A building permit in nearly every jurisdiction, usually with electrical and plumbing permits alongside it, plus inspections at set stages. Barrier and alarm requirements are part of the approval rather than an afterthought. Setbacks from the property line, from septic fields and from overhead lines all get checked. Your builder should pull the permits and own the inspection schedule; ask in writing who does it.
How long does a pool build take?
Longer than the days of actual work suggest. The sequence is layout and excavation, steel and plumbing, the shell, then inspections, then decking, then the interior finish and the fill. Between those stages sit waits for inspectors, for cured concrete and for subcontractors. Rain stops the dirt work entirely. Ask for the sequence in writing with the gaps named rather than a single finish date.
What should the contract spell out?
The shell specification, what is an allowance rather than a fixed price, the payment schedule tied to completed stages, how a change is priced and approved, who pulls permits, and who is responsible for restoring the yard. Allowances for coping, decking and tile are where budgets quietly grow. Never let the payments run ahead of the work that is finished on site.
What does the warranty actually cover?
Usually three separate things. The shell structure carries the longest term from the builder. The interior finish and any liner carry a shorter one. Pumps, heaters and controls are covered by their manufacturers, and that coverage often depends on registration and on a licensed installer. Ask who answers the phone for a leak, since a leak can sit under the deck rather than in the shell.
