check out X-Spas. (Google—you’ll find them). They’re fairly small, but they’re cheap, portable, run on 110 power, don’t have a heating coil (the first thing that usually fails on a hot tub, because of corrosion), and they’re all one piece. Only one surface material to clean.
I love mine. I hauled potted shrubbery for 12 weeks at a big-box hardware store for it, and it was worth every sore muscle!
