1. The Three Tiers of Installation
Most Long Island homeowners fall into one of these three project categories:
| Package Level | Estimated Investment | What’s Included |
| Basic Installation | $55,000 – $75,000 | Fiberglass shell, delivery, excavation, standard filtration system, and basic gravel backfill. |
| The “Staycation” Standard | $75,000 – $110,000 | Everything in Basic, plus salt-water system, LED lighting, a 3-foot concrete or paver “apron,” and basic electrical hookups. |
| Turn-Key Luxury | $120,000 – $180,000+ | Full backyard transformation: custom masonry (Travertine/Cambridge), pool heater, automated cover, code-compliant fencing, and landscaping. |
2. Average Costs by Pool Size
Fiberglass pools are prefabricated, and shipping a 40-foot shell to a tight Massapequa or Huntington backyard requires specialized equipment.
Small (up to 26’): $55,000 – $70,000
Best for: Compact lots in Nassau County or “Cocktail Pools.”
Medium (27’ – 34’): $70,000 – $95,000
Best for: Families looking for a mix of play area and lounge seating.
Large (35’ – 40’+): $95,000 – $130,000+
Best for: Large Suffolk County estates and serious lap swimmers.
3. The “Long Island Factor”: Local Hidden Costs
Dominating the local niche means being honest about the expenses other builders hide until the contract is signed:
Permits & Engineering ($1,500 – $4,500): Long Island towns (like Oyster Bay, Smithtown, or Southampton) have some of the strictest pool codes in the country. This includes surveys, architectural drawings, and permit fees.
High Water Table Mitigation ($2,500 – $5,000): If you live in a coastal area (like Babylon or the South Shore), we must install a dewatering system to ensure your pool shell remains stable.
Code-Compliant Fencing ($4,000 – $12,000): NY State law requires specific fencing heights and self-closing gates. The cost varies based on whether you choose decorative aluminum or privacy PVC.
Electrical & Gas Lines ($4,000 – $8,000): Running power for the pump and gas for the heater can vary depending on the distance from your home’s main meter.
4. Why Fiberglass is the “Smart Money” Choice for LI
While the upfront cost is similar to a vinyl liner pool, fiberglass is the superior Long Island investment for three reasons:
Lower Maintenance: Unlike vinyl, there is no $6,000 liner replacement every 7 years.
Salt-Water Compatible: Fiberglass is naturally resistant to salt, which is the preferred sanitation method for LI homeowners.
Speed of Install: We can often have you swimming in weeks, not months, avoiding the “construction zone” backyard all summer long.

No two backyards in Nassau or Suffolk are the same. Soil conditions, property slope, and utility access all play a role.
