We have a used hot tub and would like to know which way to go. Which would be easier or more economical, If it’s the wood deck,would it hold the weight? I guess it doesn’t have to be up very high off the ground. The hot tub is 8′ X 8′. Usually a concrete pad would be about 4 inches thick, right? My husband had even mentioned using those paver blocks that are like 2 inches thick. Would they be a good or bad idea?
