Marble Finished Pools builds and installs fibreglass pools made in New Zealand, including in-ground, above-ground, small and plunge designs, and it says it is the biggest NZ-owned pool manufacturer. The pools are made locally and are normally ready in about two weeks, with ribbing and extra structural support designed for NZ's flooding, shifting water table and earthquakes. Each pool has a ledge around its whole edge, so small children have somewhere to rest and a route round to the steps. The walls are steeper, which gives a larger volume of water than many imported pools, and some colours can be heated up to 35 degrees. Above-ground pools have extra supports added during manufacture. Buyers get in touch and are walked through a three-step process, and the business is at 22 Hereford Street in Springvale, Whanganui.
