I had been thinking about purchasing a hot tub for about 3 weeks, but then I saw a oversized hot tub called a exercise pool. VERY COOL! Much bigger and they seem to have some awesome features. Plus I could stop going to the gym to work out. Might seem like a stupid question, but can you turn up the water temperature to be similar to a hot tub if you want the therapeutic benefits instead o swimming laps. Might be the best of both worlds.
