We have been reviewing inflatable hot tubs since 2015. In that time we have spent more than 40 hours researching them to find the best portable hot tubs on the market. The best hot tub we found was the Coleman Lay-Z-Spa 54131E. The Coleman hot tub is attractive and built for durability with a synthetic leather exterior, polyester-mesh-enforced PVC walls and vertical beams to prevent it from buckling and bending after repeated use. It has 120 bubble jets and can heat to 104 degrees Fahrenheit, and it can fit up to six adults.  
Size: When you see models claiming is ideal for this or that number of people, first you have to bear in mind the size of your people. A 4 person profile may be claimed considering slim, average stature people, so if you have only 2 adults and kids, the tub will make room for more than 4 for sure. This scenario will interchange always depending of criteria of comfort for each person too.
Our number one choice is the Coleman Inflatable Tub. It's reasonably priced, fits four to six adults and offers better quality than the other two choices. However, you've been given the details- the good, the bad and the ugly- on each hot tub. It's up to you to determine which hot tub best suits your situation and lifestyle. Happy portable hot tub hunting, and we hope that you find the one that fits you the best.
So like we touched on already, the main safety feature is a cover. This cover provides more than just a source of keeping the heat in and the dirt out, but it is for safety. With an inflatable hot tub, most will come with an inflatable locking top. The top will be sturdy and will be strong enough to stand on when properly in place and locked, although we don’t recommend dancing on top of it.
Upgrade your home-based spa experience by purchasing some hot tub accessories. Customize it with fun add-ons like glass holders, headrests, benches, extra filter cartridges, and a lot more. These accessories are not included in a basic blow-up hot tub set, so you might want to splurge a little more. Because nothing screams “best inflatable hot tub” quite like the one with your personal touch on it.
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.
