Who: Becky & Andy Coulsby What: plastic top mount tub & fire-heated cylinder Where: Havelock North

Their bath is too far from the house to use a hose, so Becky and Andy Coulsby use fire to heat water in a repurposed tank beside their outdoor bath.

“Hubby got an engineer at work to turn a cylinder into a water tank with legs for the fire underneath,” says Becky. “The cylinder is an old cool store compression tank with the top cut off.”

They put a firebox in a hole they dug underneath the tank. The water takes a couple of hours to heat but that doesn’t worry the couple.

They bucket the water into the bath, a simple plastic insert model, sitting in a wooden frame.

“We absolutely love it!” says Becky. “Nothing beats a starry night with a couple of candles, some music and a wine.”
