JOHNSON CITY — A local spa manufacturer, Infinity Spas, has sold its operations to a Florida company that will close facilities in Johnson City and Elizabethton, resulting in 150 layoffs that Infinity officials announced to workers Monday afternoon. Another local company that makes vinyl fencing products also announced it was in the midst of a 40-employee layoff. Infinity, which opened in 2005, worked the deal with a Tampa company, Living Water Products, over the past couple weeks. CEO Dave Hatley said severe reductions in demand had hit both companies hard since the spring. “We didn’t really see a downturn until about May or June, but the last couple months there’s just been a sharp decline,” said Hatley, whose company sold to stores like Costco and Home Depot. “Those guys are really taking a hit in the leisure products industry, which is where we fall.” Infinity’s Web site shows 12 spa models with suggested retail prices from $2,899 to $16,999, with eight of the 12 between $5,000 and $10,000. Infinity had 110 employees at its manufacturing plant on Buffalo Road and another 40 in a call center and distribution warehouse in Elizabethton. Hatley said workers will be eligible for unemployment benefits and probably additional retraining help, but added that he hated to be breaking the news. “Everybody knew things were slowing down, but I don’t think they saw a consolidation coming,” Hatley said of the local workers. “This is a great area for labor force,” Hatley said. “The cost and labor force around here is tremendous, but there’s really no other alternative for us.” He said Infinity and Living Water both were producing at about 30 percent of capacity since the sudden slowdown this summer. “There’s no way we can facilitate an operation this size with those type of economic conditions. It’s just one of those times when manufacturers have to come together and hunker down and get through this downturn.” Hatley said the acquisition will give Living Water, which manufactures Lazy Boy and Coleman branded spas mostly for pool and spa stores, to broaden its market to the mass merchants that were Infinity’s customers. They’ll keep the Infinity name on the products but make them in Ta m p a . In other news, ProPlastix International Inc., which makes vinyl fencing and window and door products, is expected to lay off 40 workers during a period that began Oct. 14 and will end Nov. 30. The news was reported Monday by the Tennessee Department of Labor and Workforce Development. A spokesman at the company’s Pennsylvania headquarters would not comment on the layoffs, but a local economic development official said he thought the company employed a total of about 50 people.
