A mid-size gunite pool (about 16×32) with a standard plaster finish in Idaho typically runs $79,000–$126,000. Spas, premium finishes, features and decking are where custom pools climb from there:
| Job | Typical Idaho price |
|---|---|
| Small gunite pool (about 12×24), plaster finish | $58,000–$84,000 |
| Mid-size gunite pool (about 16×32) | $79,000–$126,000 |
| Large or elaborate custom pool | $126,000–$262,500+ |
| Attached gunite spa with spillover | $16,000–$37,000 |
| Pebble or quartz finish upgrade | $5,500–$12,500 |
| Tanning ledge or beach entry | $3,000–$8,500 |
| Water features, lighting, fire bowls | $2,000–$16,000 |
| Decking and coping | $8,500–$26,500 |
| Rock or hard-dig excavation allowance | $3,000–$16,000 |
| Permits, engineering, soils report | $800–$4,200 |
Idaho pricing is close to the national baseline used for these estimates. 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.

Treasure Valley soils dig well with occasional river cobble; foothill lots add slope engineering and views worth paying for. Frost-depth plumbing is standard, and the dry summer means dust more than debris in the filters. Fiberglass leads the growth market for speed; gunite serves the foothills high end. Automatic covers and heaters are standard, and pool-plus-patio-cover combos fit the entertaining style.
The largest listed markets are Boise (5 companies), Caldwell (4 companies), Meridian (4 companies).
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. Idaho registers contractors at the state level — verify registration and insurance certificates. Pool permits and residential-code barrier requirements run through your city or county building department, and newer-subdivision HOAs typically add design review.
A mid-size gunite pool with a plaster finish in Idaho, ID typically runs $79,000–$126,000; small pools run $58,000–$84,000 and large custom designs $126,000–$262,500+. An attached spa adds $16,000–$37,000, a pebble or quartz finish $5,500–$12,500, and decking $8,500–$26,500. Idaho pricing is close to the national baseline used for these estimates.
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 Idaho runs late May 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. The season runs late May through mid-September with dry heat and cool nights; heaters extend both ends. Winters freeze statewide, so full winterization is standard.

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.
