Back to back / open hatchway in wall is one method.

Traversing the sink cabinet is another.  

Both require opening the wall to create a passage, especially if there is structure impeding the path.  This will likely be disruptive, dusty and time consuming.  You may need someone to paint and patch.  

The distance / path from power source to destination are the determining factors for typical prices  shown in our Menu

Hard pipe is the other method.
