Installation Time
Fiberglass: 2-4 weeks. Concrete: 3-6 months.
Maintenance
Fiberglass has a smooth, non-porous surface that resists algae. Concrete is porous, requiring more chemicals and frequent brushing.
Durability in Minnesota
Concrete can crack in freeze-thaw cycles and may need resurfacing every 10-15 years. Fiberglass flexes with temperature changes.
Cost Comparison
Similar upfront cost, but fiberglass has significantly lower lifetime ownership cost due to reduced maintenance and no resurfacing.
