The San Juan Plunge fiberglass pool costs $42,995 completely installed in Massachusetts (2026) — including the 7’4″x14’6″ Glimmerglass shell, delivery, excavation, installation, backfill, cement collar, plumbing, 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 San Juan Plunge is the smallest pool in our Glimmerglass lineup — a 7’4″ x 14’6″ fiberglass plunge pool with a level 4-foot flat bottom and stadium-style entry steps. If your yard is tight or you mostly want to cool off, soak, and unwind, this is the one.
Small pool, small project: less excavation, less patio, less fence — a plunge pool keeps the whole budget down, not just the shell. And a flat bottom means everyone stands comfortably, edge to edge.

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 $42,995 include?
Everything to put a working pool in your yard: the San Juan Plunge shell, delivery from the factory, excavation, professional installation, backfill, cement collar, plumbing, 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.
