What would you do?
Due to some tile spacing issues, it was better to extend the tile to butt up against the door jamb on the left. The right end on the adjacent wall with open shelving will be bull-nosed right to the edge of the wall.
question #1...should I extend the tile on the left wall down to the baseboard along the lower cabinet?
question # 2...should I extend the tile on the left side up the side of the cabinet to the same height as the tile under the shelf?
