Simply put, no other spa is a D1. Every one of our creations is a sublime blend of science, technology and imagination. Our study of the human form, design, transfer of energies and relaxation techniques culminates in spas that are unique in every way. The result: state-of-the-art spas that conform to the body, are environmentally friendly and virtually take care of themselves. At D1, we've taken the work out of spa ownership with our proprietary, patented technologies. By combining Style and Art, we have designed a hot tub that appeals to your soul as much as it soothes your body. A hot tub so Smart and Reliable that it practically maintains itself; Pure and Simple. And in our pursuit of the Ultimate in Comfort and Performance, our engineers have studied human anatomy, ergonomics, fluid mechanics, aquatic massage, acupressure and reflexology so extensively we actually invented a new science. We call this "Hydronomics." All D1 Spas are built to be as durable as they are relaxing. They can easily handle the most unforgiving weather. And the occasional deluge of guests. By employing more than 27 years of aquatic know-how, we create more than just spas - we create memories. Make your spa purchase an investment in your body as well as your peace of mind. Step into a world unlike any other. Step up to a D1 - a higher degree of indulgence.
