Bathrooms
I think here David likes the contrast between little tiles on the floor and larger tiles on the walls. I would prefer even larger tiles on the walls, but like the small tiles on the floor also. Nice combination. Perhaps a "frame" of a larger tile on the floor to transition from the mosaic to the walls. Again - easier to keep clean.
For powder room, deeper apron on sink pedestal cabinet to hide pipes. David thinks stones could be an interesting look.
