| Job | Typical Maine price |
|---|---|
| Vinyl liner pool, installed (about 16×32) | $51,500–$80,500 |

Maine pricing is above the national baseline used for these estimates, mainly on labor and permitting. 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.

Rocky soils and ledge are routine — put excavation language in writing — and rural lots add access logistics. Frost-depth plumbing, freeze-tolerant decks, and covers rated for snow load are simply how pools are built this far north. Vinyl liner leads, fiberglass grows every year for install speed, and heat pumps are near-universal on new builds. Simple, durable designs with automatic covers fit the climate and the character.
The largest listed markets are Portland (12 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. Maine has no general statewide contractor license, so due diligence is yours: insurance certificates, references, and recent local builds. Pool permits and residential-code barrier requirements (fencing, self-latching gates) run through your town's code enforcement office; shoreland zoning can add review near water.
Installed in Maine, ME, a mid-size vinyl liner pool typically runs $51,500–$80,500, a fiberglass pool $66,500–$97,500 and a gunite pool $86,500–$138,000. With decking, a fence and permits most complete projects land at $80,500–$172,500+. Maine pricing is above the national baseline used for these estimates, mainly on labor and permitting; 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 Maine runs mid-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. The unheated season runs from mid-June to early September, and a heat pump can extend it. Winters are long and freezing statewide, so inground pools need a full close.

Budget $1,300–$3,200 / year for chemicals, electricity and routine service, more for a heated pool or a weekly cleaning route. Fiberglass and vinyl surfaces use fewer chemicals than plaster; a variable-speed pump and an automatic cover cut running costs the most.
