Installed prices in Washington run from $54,000–$84,000 for a mid-size vinyl liner pool to $90,000–$144,000 for a comparable gunite pool, with fiberglass in between at $69,500–$102,000. Decking, fencing and permits stack on top:
| Job | Typical Washington price |
|---|---|
| Vinyl liner pool, installed (about 16×32) | $54,000–$84,000 |
| Fiberglass pool, installed (about 14×30) | $69,500–$102,000 |
| Gunite / concrete pool, installed (about 16×32) | $90,000–$144,000 |
| Attached spa or spillover | $14,500–$42,000 |
| Decking and coping around the pool | $7,000–$24,000 |
| Safety fence and gates | $2,400–$7,200 |
| Permits, engineering, utility locates | $600–$4,200 |
| Typical all-in project with deck and fence | $84,000–$180,000+ |
| Ongoing upkeep (chemicals, power, service) | $1,300–$3,300 / year |
Washington 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.

Westside builds manage rain: drainage design, winter dig logistics, and slope engineering on view lots are the recurring themes, with glacial till and the occasional boulder in the dig. Eastside soils dig easier but winters freeze harder — frost-depth plumbing statewide. Fiberglass and vinyl lead for install speed under rain-window scheduling; gunite serves the view-lot high end. Heat pumps, automatic covers, and integrated hot tubs are the regional standard kit.
The largest listed markets are Vancouver (25 companies), Bellevue (24 companies), Bremerton (22 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. Washington requires contractor registration with bonding and insurance — verify both on the state's site in a minute. Pool permits and residential-code barrier requirements run through your city or county, and critical-area rules (slopes, streams, wetlands) add review on plenty of Puget Sound lots.
Installed in Washington, WA, a mid-size vinyl liner pool typically runs $54,000–$84,000, a fiberglass pool $69,500–$102,000 and a gunite pool $90,000–$144,000. With decking, a fence and permits most complete projects land at $84,000–$180,000+. Washington 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 Washington 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. West of the Cascades expect a mid-June-to-September window with mild, gray shoulders — heat pumps and solar covers are what make the investment rational. East of the mountains, summers hit 95°+ and the season stretches noticeably longer.

Budget $1,300–$3,300 / 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.
