Hot tub or swim spa, what is the difference?
Retailers that have had customers ask to test a swim spa but cannot oblige because they do not carry them could be missing an emerging wave of new buyers. Although swim spas are not new to the hot tub industry, an increasing number of manufacturers now have a swim spa line. The reason for this is because these units serve the niche fitness market—one for which most consumers did not know they were looking for until seeing them in action.
