Anne DeCocco Looks like Carrera tiles to me. What a beautiful space.

thebuilderdepot.com I believe It is Carrara Venato 12x24". They have purposely selected a whiter based marble with less veining than the classic Bianco Carrara. The whiter based stone coupled with the larger format tile tiles creates a less busy and overall cleaner look. We offer the very same tile in polished and honed for $9.95SF http://www.thebuilderdepot.com/cama12x24honed.html

We also offer the same type of Basketweave (pictures attached) for $10.95SF http://www.thebuilderdepot.com/venato-carrara.html
