Companies in the second group are listed as pool builders; most build inground pools in at least one material — ask which types they install and how many they completed last year.
Installed prices in Caldwell run from $47,500–$73,500 for a mid-size vinyl liner pool to $79,000–$126,000 for a comparable gunite pool, with fiberglass in between at $61,000–$89,500. Decking, fencing and permits stack on top:
| Job | Typical Caldwell price |
|---|---|
| Vinyl liner pool, installed (about 16×32) | $47,500–$73,500 |
| Fiberglass pool, installed (about 14×30) | $61,000–$89,500 |
| Gunite / concrete pool, installed (about 16×32) | $79,000–$126,000 |
| Attached spa or spillover | $12,500–$37,000 |
| Decking and coping around the pool | $6,500–$21,000 |
| Safety fence and gates | $2,100–$6,300 |
| Permits, engineering, utility locates | $500–$3,700 |
| Typical all-in project with deck and fence | $73,500–$157,500+ |
| Ongoing upkeep (chemicals, power, service) | $1,200–$3,100 / year |
Idaho pricing is close to the national baseline used for these estimates. Soil, access for excavation equipment, slope, utility relocation and the finish and feature package move a quote more than the pool's footprint does — compare itemized bids for the same size and type.
Fiberglass, gunite and vinyl bids are not comparable to each other — settle the type (or ask each builder to bid two), then compare like for like.

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.

Get at least three itemized bids for the same type and size, visit finished pools that are a few years old, and read the warranty for the shell, the finish and the equipment separately. Ask how the company handles rock, groundwater and access problems once digging starts. 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.
Installed in Caldwell, ID, a mid-size vinyl liner pool typically runs $47,500–$73,500, a fiberglass pool $61,000–$89,500 and a gunite pool $79,000–$126,000. With decking, a fence and permits most complete projects land at $73,500–$157,500+. Idaho pricing is close to the national baseline used for these estimates; the size, finish, features and site conditions move the number most.
There is no single best type. Fiberglass installs fastest and is the easiest to maintain but comes in fixed shapes; gunite can be any shape with any feature but costs more to build and to resurface later; vinyl liner has the lowest upfront price but needs a new liner every eight to twelve years. Match the type to your budget, your yard, how long you plan to stay and how much maintenance you want.
A fiberglass pool is often swimmable two to six weeks after excavation; a vinyl liner pool four to eight weeks; a gunite pool eight to sixteen weeks because the shell has to cure before tile, coping and the finish go on. Permitting adds two to eight weeks up front, and decking and landscaping follow the pool. Most crews dig in the off-season so the pool is ready when the season opens.
Most residential pools are 3 to 6 feet with a deep end of 6 to 8 feet; diving depths of 8 feet or more need a longer pool and a larger excavation. Fiberglass shells are limited to the manufacturer's molds (commonly 6 to 8 feet), while gunite and vinyl liner pools can be built to almost any profile, including sport pools that are shallow at both ends.
The outdoor season in Caldwell 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.
