Think carefully about where you want to put your hot tub. There are practical considerations—for a start it needs to be a flat surface. Keep in mind that your spa will contain almost 200 gallons of water, plus up to four people—that could be more than a literal ton of weight. If the tub is put straight on grass you might have a problem with it sinking, and a deck or platform would need to be pretty sturdy. It needs to be close to a power outlet, and have space around the water spa to be able to enter from any side, but also think about the route that people are going to take between the house and tub—you don’t want to get dirt in the water. If you’re planning to use your hot tub at night, make sure the area is lit.
