Fibreglass pools are cost-effective, low-maintenance, and quick to install, with a lifespan of 25-30 years. Concrete pools offer limitless design customisation and durability exceeding 50 years, but they demand higher maintenance and resurfacing every 10-15 years.
Fibreglass is ideal for simplicity and efficiency, while concrete suits those seeking fully customised, long-lasting designs.
Cost Comparison
Initial Costs
Fibreglass pools typically range from $40,000 to $90,000, with customisations such as tanning ledges or water features driving costs higher. Concrete pools begin at $50,000 and often exceed $120,000, especially for larger or more intricate designs.
Lifetime Costs
Maintenance costs differ significantly. Over a decade, fibreglass pools cost around $4,000 to $5,000, primarily for occasional chemical treatments and electricity. In contrast, concrete pools demand $25,000 to $35,000, accounting for resurfacing, acid washing, and higher chemical usage.
Summary of Financial Differences
Though installation costs overlap for small or mid-sized designs, fibreglass pools are substantially less expensive long-term. Maintenance alone for concrete pools can be up to 700% higher over ten years.
Installation Time
Fibreglass Pools
Fibreglass pools are pre-fabricated and transported to the installation site, drastically reducing the time needed for setup. Installation is often completed in as little as 2-6 weeks, including site excavation, plumbing, and decking.
Concrete Pools
Concrete pools require on-site construction involving excavation, rebar framing, concrete spraying, curing, and finishing. The timeline ranges from 3 to 6 months, with weather and site conditions potentially extending this.
Maintenance Requirements
Fibreglass Pools
Fibreglass pools have smooth, non-porous surfaces that resist algae build-up, reducing the need for regular brushing and harsh chemical treatments. Routine maintenance costs are lower, averaging $400 per year for electricity and minimal chemical use.
Concrete Pools
Concrete pools require more upkeep due to their porous surfaces, which encourage algae growth. Weekly scrubbing, acid washing every 3-5 years, and resurfacing every 10-15 years add significant costs.
Durability and Longevity
Fibreglass Pools
Fibreglass pools are highly durable, with an expected lifespan of 25-30 years. The gel coat finish resists wear, and fibreglass’s flexibility makes it less prone to cracking.
Concrete Pools
Concrete pools are sturdier but demand resurfacing every 10-15 years, costing $6,000 to $12,000 per session. Despite their longevity, reaching 50+ years often requires significant investment in repairs and maintenance.
Design and Customisation
Fibreglass Pools
Manufactured in pre-moulded shapes, fibreglass pools are limited to a maximum size of 16 feet in width and 40 feet in length. Aesthetic enhancements like tanning ledges, lighting, and water features can be added.
Concrete Pools
Concrete pools offer virtually limitless customisation, accommodating any shape, size, or depth. Integrated spas, waterfalls, or unique layouts like infinity edges are achievable.
Chemical Usage
Fibreglass Pools
Fibreglass pools are more chemically efficient due to their non-porous gel coat surface, reducing the need for pH and alkalinity adjustments. Annual chemical costs average $200-$250.
Concrete Pools
Concrete pools require higher chemical usage due to their porous surfaces, which increase alkalinity. Regular muriatic acid use and chemical expenses can reach $600-$800 annually, especially in warmer climates.
Algae and Water Quality
Fibreglass Pools
Fibreglass pools resist algae build-up, thanks to their smooth surface. Weekly maintenance is often sufficient to keep the pool clean.
Concrete Pools
Concrete pools, with their porous surfaces, encourage algae growth, requiring frequent scrubbing and the use of strong algaecides.
Saltwater Compatibility
Fibreglass Pools
Fibreglass pools perform well in saltwater systems due to the gel coat’s resistance to corrosion. They require minimal additional maintenance.
Concrete Pools
Concrete pools face challenges with saltwater. Salt accelerates plaster deterioration and damages grout and adhesive materials, leading to more frequent repairs.
Energy Efficiency
Fibreglass Pools
Fibreglass pools are naturally insulating, reducing heat loss and lowering energy consumption. Heating costs are significantly lower compared to concrete pools.
Concrete Pools
Concrete pools lack insulation and lose heat more quickly, increasing heating costs by 30-50%.
Environmental Impact
Fibreglass Pools
Fibreglass pools have a smaller environmental footprint due to efficient manufacturing processes and reduced chemical usage.
Concrete Pools
Concrete pools consume more resources during construction and require higher chemical use and energy consumption, increasing their environmental impact.
