If you’re thinking about a hot soak at home, there are lots of reasons why a durable, portable Softub makes more sense than a traditional acrylic hot tub. Here are just a few: It sets up in minutes with no site prep. It plugs into a regular household outlet for power. Heating it costs less than half. When you’re done with it, one person can easily roll it away for storage or to a new spot indoors or out.
