The great thing about inflatable hot tubs is that you can set them up anywhere, whether indoors or outdoors, as long as you have the power source and the space. For indoor use, you have to consider the flooring of the room. Carpeted or wooden flooring is not waterproof and will therefore need a layer of protection. Line up some towels so you won’t be dripping and spilling water directly onto the floor.  Hot tubs are heavy, so make sure that the flooring can take the weight of the entire thing, especially when filled with water and when people are in it. The best area to place an inflatable hot tub is somewhere on the ground floor.
