Medium size shower in 12x24 larger tile. You don't have to make a shower in old 4x4 or 6x6 tile. Google 12x24 showers and see the exiting possibilities.
We are not sure, but we think the customer removed a few of the darker tiles as this tile is more multi-mixed. This is a V4 variation tile. V1 is no variation and V4 is dark to light colors mixed in the pattern.
