This is not a kit or prefabricated hot tub. It is essentially a mini-pool poured concrete shell construction with a stone veneer and stone cap. I have purchased hot tubs and then built stone walls etc. around them so you could do that. First thing to do is select the tub. Try Sundance Spas i've used them with great success. Let me know how you make out. -Good Luck!!

I am assuming these cobbles are old material, not new?
