Thank you for your question! The wall tile is Ambra Gris from the Hand Carved collection by Artistic Tile. The floor tile is Zebrano from the Vestige collection also by Artistic Tile.

I don't see the brown tile on the artistic tile website. The ambra gris seems to be the wavy looking stone on the left side of the bathroom. What is the brown tile on the back and right side? Where can I buy it? How much per tile?

NVM. I found the dark tiles. They are the Horizons Brown Matte Field Tile seen here: http://www.artistictile.com/productdetails.aspx?Colid=77&Cid=50

After looking at the picture again, I'm wondering if the shower wall is a mix of the brown and grey matte field tiles..???

These are not 12x24" tile like the link above...proportions are not what a 12x24 would look like and ceiling height doesn't add up because it would make the ceiling 12 feet high (there are 12 tiles from floor to the ceiling which is 144" or 12 feet) and this is not a 12 foot high room judging by the vanity height. This looks more like an 8-9 foot ceiling. They seem longer and narrower maybe 8"x24" or more? If they are 8" that would make the ceiling about 8' or if the ceiling is 9' then the tile is around 9" high and it probably longer than 24" judging by the proportions. Love the size if anyone knows exactly what it is.
