Installed prices in North Dakota 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 North Dakota price |
|---|---|
| Vinyl liner pool, installed (about 16×32) | $47,500–$73,500 |
| Fiberglass pool, installed (about 14×30) | $61,000–$89,500 |

North Dakota 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.

Extreme frost depth drives plumbing, shell, and deck engineering; wind exposure shapes everything above grade. The build season is compressed, so builders pull permits over winter and dig the moment ground allows. Fiberglass leads for install speed, with vinyl liner alongside; heated, auto-covered compact pools are the sensible local standard. Above-ground pools hold a big share statewide.
The largest listed markets are Minot (4 companies).
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. North Dakota licenses contractors at the state level — verify the license and insurance certificates. Pool permits and residential-code barrier requirements run through Fargo, Bismarck, or your city's building department.
Installed in North Dakota, ND, 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+. North Dakota 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 North Dakota runs June through early September — about 3 months unheated. A full professional winterization each fall protects plumbing and equipment through the freeze, and spring openings cluster into the same few weeks. June through early September unheated; heaters are standard equipment, not upgrades. Winters are among the harshest anywhere pools are built — frost runs deep and stays.
