I have an existing hot tub that I need to move and a new one I need to move in when it arrives. What is the best way to move these? What kind of equipment do I use? Should I hire someone, or would regular guys be able to do it?

My best advice if you are able to keep your spa on the same level, would be to empty the spa as complete as possible. Then use PVC pipes 2 - 4' lengths. Roll the spa on the pipe slide one after then other, after the other, after the other until your spa is out of the way. This is a nice way to move your spa if you dont want any huge scratches in your deck.

Hope this helps!
