The Extreme 27 fiberglass pool costs $66,495 completely installed in Massachusetts (2026) — including the 12’6″x27′ Glimmerglass shell, delivery, excavation, installation, backfill, cement collar, plumbing, spa air system, propane spa heater, pool water, building permit, and MA sales tax. Most pool companies won’t publish installed prices — we think you deserve the number before the sales call.
The Extreme 27 is a 12’6″ x 27′ fiberglass pool with a built-in spa and tanning ledge — pool, hot tub, and splash pad in one shell, one dig, one project.
The integrated spa means no separate hot-tub purchase, no second pad, no extra plumbing project — the air blower system and its plumbing are already in your installed price.

Available Colors: Ocean Blue, Sapphire Blue, Coastal Bronze, Snow White, Steel Grey, Arctic White, Glacier Blue

Why Glimmerglass?
Glimmerglass has been manufacturing fiberglass pools in New York since 1999. Their shells use hand-laid solid fiberglass sheets with vinyl ester resin and a fade-resistant gelcoat finish. Their process is as good as it gets! BBB accredited, A+ rated.
They are local East Coast USA Fiberglass Company so shipping to Massachusetts is going to be the least expensive!

Fiberglass Pool Pricing FAQ
What does the $66,495 include?
Everything to put a working pool in your yard: the Extreme 27 shell, delivery from the factory, excavation, professional installation, backfill, cement collar, plumbing, spa air system, propane spa heater, pool water fill, your building permit, and Massachusetts sales tax.
What is NOT included?
Three things most homeowners arrange locally: electrical service with bonding ($3,000–$8,000 by a licensed electrician), a gas line if you choose a propane heater, and landscaping. Patio, pool fencing (required by code), pumps, filters, heaters, and lighting are priced à la carte — get your full all-in price using the estimator app.
I’m in New Hampshire — do I pay Massachusetts sales tax?
No. NH has no sales tax, so once we verify your NH delivery address, a tax-free discount comes off the listed price at contract.
What happens after I build my estimate?
Mike personally reviews it, then schedules your free site evaluation. Site conditions like ledge, water table, and access are confirmed there, and your final contract price is locked in before any work begins.
