A mid-size gunite pool (about 16×32) with a standard plaster finish in Shelton typically runs $90,000–$144,000. Spas, premium finishes, features and decking are where custom pools climb from there:
| Job | Typical Shelton price |
|---|---|
| Small gunite pool (about 12×24), plaster finish | $66,000–$96,000 |
| Mid-size gunite pool (about 16×32) | $90,000–$144,000 |

| Rock or hard-dig excavation allowance | $3,500–$18,000 |

Connecticut 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.

Rock is the Connecticut surprise — ledge shows up across the state and blasting or hammering can move a budget, so insist on a written rock clause. Wooded lots mean tree work and leaf-driven fall maintenance, and older towns add tight-access builds and wetland setback reviews. Gunite with spas and stone terraces owns Fairfield County; vinyl liner carries the rest of the state on value. Automatic safety covers are near-standard on new builds, and compact heated pools are gaining as lot sizes shrink.

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. Connecticut home improvement contractors register with the state Department of Consumer Protection — verify it along with insurance certificates. Pools permit through your town's building office with residential-code barrier requirements (fencing, self-latching gates, and alarms where required); shoreline towns and inland wetlands commissions can add review steps.
A mid-size gunite pool with a plaster finish in Shelton, CT typically runs $90,000–$144,000; small pools run $66,000–$96,000 and large custom designs $144,000–$300,000+. An attached spa adds $18,000–$42,000, a pebble or quartz finish $6,000–$14,500, and decking $9,500–$30,000.

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. Freezing weather pauses shell and plaster work, so most builds are scheduled for the warm months.
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 outdoor season in Shelton runs June through mid-September — about 4 months unheated. A full professional winterization each fall protects plumbing and equipment through the freeze, and spring openings cluster into the same few weeks. Realistically June to mid-September unheated, with heaters buying May and October. Humid summers, cold winters, and a hard freeze season mean full winterization is simply part of owning a pool here.

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.
