Dimension One Spas

Dimension One Spas® (D1®), founded in 1977, is one of the world’s leading firms in the design and manufacture of luxury home hot tubs/spas and aquatic fitness systems, commonly known as swim spas. The family-owned business combines its innovations in materials science and water handling technology to bring customers some of the most advanced products in the world engineered to rejuvenate body, mind and soul.

Headquartered in Vista, California, D1 was founded by Bob and Linda Hallam. In the early 1970's the Hallams were marketing a line of portable spas at a time when most hot tubs were in-ground. The aboveground spas sold well, but after conducting grass-roots marketing research, the Hallams found that consumers were looking for something distinctly different than the traditional round hot tub. After surveying their customers, they returned to their manufacturer with a long list of features people were looking for in a spa.

When the manufacturer declined to stray from the standard mold, the Hallams took the challenge to go into business for themselves and manufacture a spa that would respond to consumer demands and needs. Based on their research, they produced a spa with 8 unique features not found in any other portable spa, and before they knew it, they could hardly keep up with local demand. Bob Hallam took their new spa on the road to various trade shows and established a strong dealer base. By 1986, D1 had become a major player in the hot tub industry.

D1 hot tubs and aquatic fitness products are now sold through a network of more than 250 dealers in the United States, and 450 dealers worldwide in 30 countries. The company's three product lines include a range of home hydrotherapy and aquatic fitness products that meet a variety of consumer needs and budgets: D1 Reflections®, D1 Bay Collection®, AFS- Aquatic Fitness Systems® and @ Home Hot Tubs®. D1's phenomenal growth necessitated the building of a state-of-the-art, 135,000 square foot manufacturing plant and headquarters in 1999. At the peak of its season, the $10 million dollar facility is home to more than 400 employees.

Passion for innovation has driven D1 Spas for nearly three decades. That's because they believe it will never be enough to do what they have always done, or simply to copy what others are doing. In fact D1 Spas holds over 30 patents on hot tubs and spas; more than any other hot tub or spa manufacturer.

By combining Style + Art, they have designed hot tubs and spas that appeals to your soul as much as it soothes your body. A hot tub so Smart + Reliable that it practically maintains itself; Pure + Simple.

In their pursuit of Ultimate + Performance their engineers have studied human anatomy, ergonomics, fluid mechanics, aquatic massage, acupressure and reflexology so extensively they actually invented a new science; they call it "hydronomics."
