The two-person Softub 140 doesn't have the fancy seats, variety of jets, or adjustable controls found in more expensive acrylic spas, but you can move it indoors or outdoors in a jiffy. Plus, this model not only costs less, but it's also cheaper to run since it uses heat recovered from the pump to keep it toasty hot. You will, however, have to use special vinyl-compatible chemicals, since regular pool chemicals will harm the Softub's plastic. A sequencer allows you to program which jets go on and off, and in what order. Simpler devices let you turn jets on and off at will, and can vary their intensity.
Many spas feature digital controls with details about temperature and filtration .
While not strictly necessary, they can be nice if you're the sort of person who likes to know the status of everything. While it may seem silly in the showroom to think about a light in your spa, many owners who pass on this feature regret it later . Not only are lights visually appealing, they save you from sitting in the dark at night. The fancier the seating arrangements, the more crowded your tub will feel . Two loungers and a captain's chair might be comfy, but they do take up space.
