Phelps introduces line of spa pools

LAS VEGAS, Nov. 4 (UPI) -- Michael Phelps, the much medaled U.S. Olympic swimmer, is lending his name and expertise to a new line of mini-swimming pools, an Indiana company says.

Master Spas said Phelps and his coach, Bob Bowman, assisted in the design off a new line of six swim spas or mini-pools, The Baltimore Sun reported Thursday. In the pools, a current of water can be switched on to create a sort of aquatic treadmill.

Phelps won six gold medals and two bronze at the Athens Olympics in 2994 and eight golds in Beijing four years later -- a record gold medal count for a single Olympics. But his marketability took a hit early last year when he was caught on camera smoking marijuana.

In February, Phelps signed an endorsement deal with Under Armour, a Baltimore maker of sports apparel.

Phelps joined Master Spas Chief Executive Officer Bob Lauter for the introduction of the Michael Phelps Signature Swim Spas line Wednesday at the International Pool Spas Patio Expo in Las Vegas. The line ranges in price from $25,000 to $45,000.
