No tub is free, there are some things you may want or need to do right away:
Dealers charge $400 to move a spa out here - give or take.
New cover - $400 give or take.
Wiring? Call for estimates.
Supplies? You may get enough from the previous owner to get started.
Rubber duck? Priceless.
Just keep these things in mind, not that they come even close to the price of a new tub.
You can really enjoy a tub, it's a nice place to go unwind and forget about the day, or connect with family or friends. and it seems all that much sweeter if you get it for so little.
