Dimension One Spas® was founded by Bob 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 Hallam received requests from their retail customers that were not being fulfilled by hot tub makers at the time, the husband-wife team 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 square foot manufacturing plant and corporate headquarters. D1 is – and always has been – at the forefront of spa industry innovation.
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. Plus for six years D1's hot tubs have achieved the Spasearch Buyer Guide's highest "Recommended" rating - see more about our awards.
