I think I made my decision with Jacuzzi J375 series.. The question i have is I was told the electrical connections have to be in the proper location and must be perfectly placed. I am having a concrete slab poured and need to know where to place the electrical connection prior to concrete. I called Jacuzzi but didnt really get an answer. Does this tub have connection that go in on the side of tub? does it stick out so people can trip or kids can touch the pipe or wire? Does anyone have pics of there install with wires.. I cannot screw this up and waiting for responses so I can start the electric work . please shot me a message or pics would be great.. I thought maybe there would be a paper to place on concrete and would show where the holes / wires would come in but doesnt seem so...any help is great !!
