WHEN IT COMES NATURALLY

There’s been a surge of interest in pools that are chemical-free and take their design cues from wild swimming holes, says Wayne Zwar, owner of Natural Swimming Pools Australia. The firm designs and builds in-ground billabong-style pools, such as the one shown above. This type of pool requires no chlorine, instead using aquatic plants to oxygenate the water and filter it (in tandem with a sophisticated submerged pump system). “Natural swimming pools are more expensive,” says Zwar, “but the sensation of swimming in ‘living water’ really can’t be beaten.”
