traditional Carrara. Given the lighter nature I would suggest it is a Venato Carrara. And yes 12x12" marble tile along with Venato Carrara 1" Hexagon mosaic. Attached is a picture from the Carrara Venato collection. We offer in the same stone, Hexagon 1" and 2", Basketweave, Herringbone, Octagon and various
tiles. Carrara Venato can be a lighter stone to Carrara Bianco especially when Carrara Bianco from the Italian quarries are running gray.
Appears to be a 12x2 Carrara on the walls with Carrara hexagon on the floor.
Fixture is very similar to master shower fixtures. Same hexagon style tile in master
hexagon floor,carrerra shower and frameless shower door
Carrara hex tile floor with square tile in shower, no tile on bathroom walls
