Like a spa, a hot tub has built-in jets to provide warmth, relaxation and a massage effect on people's muscles and joints. Both are used for therapeutic reasons and socialization. In the early days—the late 1960s and early 1970s—hot tubs were made from wood, including cedar, redwood, cypress, teak, or a composite. In the mid-1970s, the technologically advanced portable acrylic spas were introduced, replacing the wooden tubs in popularity.
Ideal Size for Your Needs Is it for just solo or 2-person dips? Or are you planning on having the whole family enjoy the tub? Its size should suit your plans on how you’re going to use it. What you may realize is that a supposed 6 person portable hot tub is actually a comfy 4 person portable spa. A 4 person hot tub is really a 2 person portable spa, with perhaps 2 small kids. And you don’t want to get a 2 person portable hot tub unless you plan on using it solo.
If you do like to move it around regularly, which is the strongest advantage for inflatable hot tubs, you have to deal with draining, deflating, moving, inflating, and refilling your tub every time you want to move it. The deflating and inflating isn’t as big of a deal if you have an air compressor to hook up to it, or if your hot tub came with its own, but it still takes a while (and a good deal of water) to refill that hot tub every time, and longer yet to get the water hot.
