A mid-size gunite pool (about 16×32) with a standard plaster finish in Fullerton typically runs $97,500–$156,000. Spas, premium finishes, features and decking are where custom pools climb from there:
| Job | Typical Fullerton price |
|---|---|
| Small gunite pool (about 12×24), plaster finish | $71,500–$104,000 |
| Mid-size gunite pool (about 16×32) | $97,500–$156,000 |

| Attached gunite spa with spillover | $19,500–$45,500 |
| Pebble or quartz finish upgrade | $6,500–$15,500 |
| Tanning ledge or beach entry | $4,000–$10,500 |
| Water features, lighting, fire bowls | $2,500–$19,500 |
| Decking and coping | $10,500–$32,500 |
| Rock or hard-dig excavation allowance | $4,000–$19,500 |
| Permits, engineering, soils report | $1,000–$5,200 |
California pricing is above the national baseline used for these estimates, mainly on labor and permitting. Gunite bids vary more than any other pool type because every element is custom — compare the shell thickness, steel schedule, finish, feature and equipment lines, not just the bottom number.
Spas, ledges, benches, lighting niches and water features are cheapest when they are shot into the shell — adding them later means cutting concrete.

Terrain drives engineering: hillside lots need soils reports, caissons, or retaining structures, and every shell is built to seismic-conscious standards. Expansive soils show up across the state, so structural engineering isn't the place to save money. Title 24 energy rules mean variable-speed pumps are the standard spec, not an upgrade. Infinity edges on view lots, pebble interiors, baja shelves, and increasingly small, deliberate pools — plunge pools, cocktail pools, and spools that fit tight lots and tighter water budgets. Automation and solar heating adoption lead the nation.

Ask for the shell engineering and the gunite crew's track record, read the structural, finish and equipment warranties separately, and compare at least three itemized bids for the same design. Pool builders need a CSLB C-53 swimming pool contractor license — verify it (and the bond) on the state's site in about a minute. California also requires new and remodeled pools to include two of seven approved drowning-prevention safety features, and many water districts add rules on filling and draining during drought years.
A mid-size gunite pool with a plaster finish in Fullerton, CA typically runs $97,500–$156,000; small pools run $71,500–$104,000 and large custom designs $156,000–$325,000+. An attached spa adds $19,500–$45,500, a pebble or quartz finish $6,500–$15,500, and decking $10,500–$32,500.

Both are concrete sprayed over a steel cage. Gunite is a dry mix with water added at the nozzle; shotcrete is wet-mixed concrete pumped through the hose. Each produces a strong shell when applied by a good crew — the nozzleman's skill, the mix design and proper curing matter more than which method is used. Ask which your builder uses and what thickness is specified.
Plan on eight to sixteen weeks from excavation to swimming: dig and steel in the first week or two, the shell shot and cured for about four weeks, then tile, coping, plumbing, equipment, decking and finally the plaster and fill. Permits add two to eight weeks before the dig. Builders here work year-round; weather delays are mostly rain.
The concrete shell can last 50 years or more. The plaster finish lasts about 10 to 15 years (quartz and pebble 15 to 20 or more), waterline tile and coping 15 to 25 years, and equipment 8 to 15 years. Balanced water, especially calcium hardness and pH, is what protects the finish.
The prime outdoor season in Fullerton runs May through October along the coast, longer inland — roughly 6 months of comfortable unheated swimming — and pools stay open and running year-round rather than being winterized. The coast swims May through October (heaters stretch it), while the Central Valley and desert run hot enough for six-plus unassisted months. Pools stay open all year, winter is mild, and evaporation — not freeze — is the seasonal enemy, especially inland.

Usually, for the same size: the shell is built on site, the finish is a separate trade, and custom features add up. The gap narrows for large pools and designs with spas and ledges, where fiberglass models are limited. Over 20 years a gunite pool also needs at least one resurfacing, which is part of its true cost.
