First you will want to see how big the hot tub is, if you plan on having parties, make sure you get an adequate sized hot tub. Also choose what material you want, which will depend on your budget.

This will depend on what you want to use the hot tub for. Before you go shopping, decide how much seating you will need. Measure the dimensions of the space you want to put the hot tub - does it fit? Power hookup is also a consideration, as a lot of tubs use a 240v source. I suggest finding a local retail source you are comfortable with, as they will have people to help you find a personal fit.
