San Juan VS Competitors
One simple truth drives everything we do: building the highest quality fiberglass pools in the world. See how San Juan's hand-laid process compares — point by point.

The San Juan Advantage
Nearly 70 years of hand-laid craftsmanship. The first fiberglass pool San Juan ever built is still in the ground today.
100% Hand-Laid Sheets
Multiple layers of solid fiberglass sheets applied sequentially — replicating the same boat hull manufacturing process used in marine applications.
Vinyl Ester Throughout
Marine-grade Vinyl Ester resin applied throughout the entire pool shell — not just the last layer. Both sides are fully protected against water intrusion.
32-mil Gel Coat
The thickest gel coat in the industry — two 16-mil layers for superior UV protection, stain resistance, and lasting color vibrancy.
No Coring or Fillers
Pure fiberglass composite throughout. No coring, no fillers, no chopped fiberglass, and no safety ledges needed — the shell is strong enough without them.

San Juan Pools
Hand-Laid Fiberglass
Competitors
Chopped / Sprayed
San Juan
100% hand-laid solid sheets with consistent thickness
Competitors
Chopped fiberglass sprayed from gun — inconsistent thickness
San Juan
Removed from each layer for optimal strength-to-weight ratio
Competitors
Cannot be removed — weakens the shell over time
San Juan
Applied throughout — significant vertical and horizontal strength
Competitors
Used only in limited areas — structural gaps remain
San Juan
Not used — zero chopped fiberglass in any San Juan pool
Competitors
2" pieces sprayed on with variable thickness throughout
San Juan
Not needed — shell is strong enough without them
Competitors
Required for stiffening — collects dirt, potential hazard
San Juan
Not used — pure fiberglass composite throughout
Competitors
Present in many models — increases brittleness risk
San Juan
Applied throughout the entire pool shell — both sides
Competitors
Last layer only — interior unprotected
San Juan
32-mil thickness — two 16-mil layers (thickest in the industry)
Competitors
27–30 mil — single layer application
San Juan
Guaranteed minimum 5 hand-laid fiberglass layers per shell
Competitors
No guaranteed minimum — varies by model and manufacturer
San Juan
Factory-manufactured with controlled QA at every step
Competitors
Variable quality — depends on spray operator skill
Hand-Laid vs. Chopped
San Juan — Hand-Laid
The right way
- Guaranteed minimum 5 hand-laid fiberglass layers per shell
- Consistent thickness throughout the entire mold — front to back
- Excess resin removed from each layer for optimal strength-to-weight ratio
- No safety ledges needed — shell integrity stands on its own
- Vinyl Ester resin throughout entire pool — both sides protected
- 32-mil gel coat in two layers — thickest and most durable in the industry
Competitors — Chopped
Cutting corners
- No consistency in fiberglass thickness — depends on spray gun duration
- Resin concentrates in random areas, creating uneven weak layers
- Requires interior "safety ledges" that weaken the shell and collect dirt
- Variable quality depends on spray operator skill, not controlled QA
- Vinyl Ester resin used only on the last layer — interior unprotected
- Thinner gel coat (27–30 mil) with single-layer application
