I am new to the forum. So Hello!! I currently want to install a hot tub outside sort of recessed in an embankment on a gravel and stepping stone (which are space roughly 12" apart). I will be putting a 50 GFCI spa panel on the wall which is roughly 15' away in line of site. I was going to rest the tub on some PT form boards. You will be able to possibly reach ground on one side and will be getting out on wooden steps on to the gravel or stepping stones. My question is on bonding if it is required and how? Is this a different type of install or has someone done this? I mean just setting a hot tub on the ground or on gravel out in a backyard?
