I have never thought of moving them, the stall is mounted against the kitchen bulkhead on the left side and the exterior wall on the right side with the valves dead in the middle on the "flat part" of the V. I am going by memory but I do not think there is enough room behind the unit or any way to get there without pulling the entire stall. It would not be a clean deal but you could pull the valves and run some hoses over to the side and face mount them, which would be pretty hillbilly at best......
