Hello, We took out a 54" vanity and sink and put in a 30" vanity. The plumbing won't be centered in this 30" cabinet it's over to the right side of it and I would have to move the cold water supply line 2" to the left to still be inside the cabinet. Is this OK to do or would the walls have to be all cut out and all of this plumbing be moved to the left and centered in the new cabinet?
