I do not offer hot stone as an out call service, due to the transportation problems. I have a hard time getting my hot water to stay in the warmer for the trip. I suppose I could put the water in a Vacuum bottle and pour it on the stones when I get there, but that seems a little extreme for me. As for the pricing, I charge a $30.00 out call fee. I also charge an extra $20.00 for hot stone when applied with Swedish or Deep Tissue.
