A mid-size fiberglass pool (about 14×30) installed in Redmond typically runs $69,500–$102,000 with standard equipment and a basic concrete deck. The shell itself is usually a third to half of that:
| Job | Typical Redmond price |
|---|---|
| Shell only, delivered (small to large) | $21,500–$54,000 |
| Small shell installed (about 12×24) | $50,500–$72,000 |
| Mid-size shell installed (about 14×30) | $69,500–$102,000 |
| Large shell installed (about 16×40) | $96,000–$138,000+ |
| Built-in tanning ledge or splash pad model | $5,000–$11,000 |
| Attached fiberglass spa | $14,500–$30,000 |
| Decking and coping | $7,000–$19,000 |
| Equipment upgrades (heater, salt, automation) | $4,000–$14,500 |
| Crane or access fees | $1,800–$6,000 |
| Permits and engineering | $600–$3,600 |
Washington pricing is above the national baseline used for these estimates, mainly on labor and permitting. Shell brand and size set the base; crane access, backfill material, decking and the equipment package explain most of the spread between quotes for the same model.
Browse the manufacturer catalogs first — most installers carry one or two brands, and the model you want decides who can bid.

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 shells arrive finished, so the local work is excavation, setting, plumbing and decking — the ground conditions and the crew's setting method matter more than with any other pool type.

Confirm the dealer is authorized by the shell manufacturer (that keeps the shell warranty valid), ask how the shell is leveled and backfilled, and compare quotes for the same model with the same deck and equipment. 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.
A mid-size fiberglass pool installed in Redmond, WA typically runs $69,500–$102,000; small shells run $50,500–$72,000 and large shells $96,000–$138,000+. The shell itself is $21,500–$54,000 delivered. Decking ($7,000–$19,000), an attached spa ($14,500–$30,000) and equipment upgrades ($4,000–$14,500) are the common extras. Washington pricing is above the national baseline used for these estimates, mainly on labor and permitting.
The structural shell commonly carries a lifetime or 25-to-35-year warranty and the gelcoat surface 10 to 20 years before it may need recoating. Proper backfill and balanced water (especially calcium and pH) are what keep the surface and the structure in shape; cobalt staining and spider cracks are usually water-chemistry or installation issues rather than shell defects.
Once the permit is in hand, most fiberglass installs are swimmable in two to six weeks: a day or two to dig, a day to set and plumb the shell, a few days for the concrete collar and deck, then fill and startup. Shell lead times from the factory can add several weeks in spring. Installers dig as soon as the ground allows and book the spring slots early.
Fiberglass wins on speed, maintenance and long-term surface cost; gunite wins on custom shapes, depth, features and size. Installed prices for a mid-size pool are often similar once a gunite pool's finish and features are included, but a gunite pool will need a resurfacing in 10 to 20 years that a fiberglass pool usually does not. Pick by shape and size first, then compare total cost of ownership.
The outdoor season in Redmond 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.
Apple Valley Pools and Excavation has the highest customer rating on this Redmond list at 5 stars across 3 reviews. Amcon Pool & Spa has the largest review count (18 reviews at 4.8 stars).

Nearly anywhere a flatbed and a crane or excavator can reach the yard — tight side yards, overhead power lines and steep lots are the usual obstacles. High groundwater needs a well point or sump during the install, and expansive clay calls for a gravel base and careful backfill. A good installer will walk the access route before quoting.
Shells range from plunge pools around 8×14 to large models around 16×40, with depths of roughly 3½ to 8 feet. Most manufacturers offer rectangles, freeforms, lap pools and models with built-in tanning ledges, benches and spas. Size is limited by what can be shipped on a truck, so very large pools are built in gunite.
