Hydro Systems Cottonwood
Hydro Systems' Cottonwood Outdoor Tub represents the peak of duality—where opposing forces, like heat and cold, come together in perfect harmony. Rooted in the ancient practice of contrast therapy, which alternates between hot and cold water immersion to enhance circulation and support muscle recovery, this spa tub offers a bold, modern interpretation of this time-honored wellness tradition. Inspired by the historic healing waters of Colorado’s Cottonwood Hot Springs, this outdoor tub captures the essence of its namesake. The hot side gently warms to 104˚F degrees, offering soothing relaxation, while the cold side invigorates with icy waters as low as 37˚F degrees, delivering the ultimate thermal contrast. This interplay of temperatures creates a restorative experience, heightened by the natural beauty of your surroundings. With 42 precision-placed jets—12 for the cold side and 30 for the hot side—you can target specific areas for personalized hydrotherapy tailored to your wellness needs.
