I do it exactly like mike Antoinette does. I cut the bottom tile up 1/8 and then mask it off and caulk the change of plane with color match caulk.

Floor tile butted to wall tile always looks bad with the grout joint(hairline crack) due to movement. It let's you tuck that edge under the wall tile. Pain and I hate doing them when it's a bunch of bathrooms, just soaks up time.

Yes it defiantly soaks up time and with bigger tile you have to measure both ends of the tile down to the floor and cut the tile on a slight taper if needed. But like you said it looks better with the floor tile tucked under the wall
