The concept of a natural pool began in Europe several decades ago. Since then, they have gained popularity in areas with a sunny climate like America, Australia etcetera. With natural pools, you can bid adieu to chemicals like chlorine and say hello to natural beauty. The idea was inspired by the joy and beauty of swimming in mountain lakes. The concept was to invite nature while swimming in a pool. They can be given irregular shapes, along with waterfalls, rocks, and boulders. However, not every pool is a natural pool. It can be designed to look like a natural water body with realistic boulders and rocks. But it might still not be real. A team of Austrian researchers is said to have launched a movement in the 1980s. They focused on replacing chlorinated swimming pools with natural swimming ponds and pools.
