A house is divided into apartments, one on each floor. For one floor which is sometimes unoccupied for lengthy periods, there is a water valve to shut the water off for the whole floor. This mitigates against water leaks developing when the floor is vacant....
If you have access then you can run a new line away from the bathroom, put a new shut off anywhere you want and then return it back to where you started. Think of a big loop with just a shut off on it.
