I'm getting eager for summer and I am extending my deck. Currently, my hot tub is sitting on the existing deck. I want to set the hot tub on the ground and build the new deck around it. Any ideas as to what to set the hot tub on instead of pouring a cement slab? I have heard of a couple of ideas, i.e. platform of treated lumber, pea rock, etc. I am considering the pea rock idea. Anyone have experience with pea rock/other ideas?
