Dimension One Spas was founded by Bob and Linda Hallam in 1977 and has grown to become one of the world’s leading manufacturers of hot tubs and aquatic fitness systems. The company was first established as a chain of retail hot tub stores. But because Bob and wife Linda received requests from their retail customers that were not being fulfilled by hot tub makers at the time, they refocused the company into manufacturing.

In less than 10 years the company established itself as a major industry player, necessitating the construction of an advanced 135,000 sq. ft. manufacturing plant and corporate headquarters. Always at the forefront of spa industry innovation, D1’s products are uniquely different.

Dimension One products are sold around the world and in 2007 D1 was awarded the Silver Medal Shingo Prize, becoming the world’s first and only hot tub manufacturer to receive the distinguished award. D1’s hot tubs have also achieved the Spasearch’s highest “Certified” rating since its inception in 2006.
