Pool type
Fibreglass shell
Pre-moulded shell, dropped in, swimming in three weeks.
A factory-built one-piece fibreglass shell, delivered on a truck and craned into a pre-dug hole. Shell sizes top out around 8.5m (longer than a NZ truck deck won't carry) and shapes are catalogue-fixed — but the build is fast, the gel-coat is genuinely low-maintenance, and total install cost is half what a comparable concrete pool runs.
