It's the classic Australian pool debate. Both have their place, but for most Melbourne backyards, fibreglass wins on three fronts: speed, cost, and maintenance.
Speed: a concrete pool typically takes three to six months from excavation to first swim. A Pizi fibreglass pool can be in the ground and ready to swim in three to four weeks — sometimes faster.
Cost: concrete pools start higher and stay higher across their lifetime, primarily because of the resurfacing required every 7-15 years. Fibreglass shells, by contrast, never need resurfacing — the gel coat is the surface.
Maintenance: smooth fibreglass surfaces resist algae, requiring fewer chemicals to keep clean. That matters during Melbourne’s long autumns when concrete pools can struggle with algae blooms.
Where concrete wins: total design flexibility. If you want an irregular shape, a vanishing edge, or a wet edge with an integrated water feature, concrete still has the edge. For 95% of suburban builds though, fibreglass delivers a better outcome for less money.
