This floor looks just like the ceramic tile (yes, ceramic tile) that we are putting in as a tub surround. I have only found it at one place, a store called Chic Tile in Redwood City, California. The tiles give no indication of their brand and despite extensive web searching and shopping at many local flooring stores, I have not found them anywhere else. I think this color is called Tanzanian Pearl, at least at Chic Tile. There are several darker shades available, but I don't remember their names.

The store owners seem to be French, so maybe this tile comes from France?

Is it wood or ceramic?

I think its White Oak with a whitewash or similar finish. We are doing a White Oiled finish over White Oak. Let me know if you have any questions. joel@oakandbroad.com

I'm sorry, I don't have the exact specifications on hand, as it was coordinated by the general contractor. Good luck with your project!
