The plunge pool is a proper organic pool (natural swimming pool), only smaller. And this one is small enough to fit in a modest garden to bring the delights of plunging into organic water to more of us. (Click image for FAQs & instruction for making one.)
Natural Swimming Pool/Ponds (NSP's) are a chemical-free, low-maintenance alternative to traditional chlorine pools. The water is clean, crystal-clear, and filtered naturally using a built-in biological filter.
