Thank you for your question and your kind words. The tile used in this shower and floor are by Walker Zanger. We purchased them from Hamilton Parker, which is an authorized dealer. Here is a link to the Walker Zanger showroom and authorized dealer location finder:

All of the tile in the shower is honed carrara marble. We used several different sizes. The floor and upper shower wall is in a 12X24 tile and the bottom is a 3X6 tile. A row of chair rail separates the two, and it is also made out of honed carrara marble. The shower floor is 1x1 mosaic sheets. The shower seat is a slab of honed carrara marble.

Walker Zanger shared a link to the Tribeca Collection which is where these products can be found. Here is a link to that collection:

The only custom piece is the 8 inch base which we custom ordered through Castellie in Italy. Here is a link to their website: http://www.castellimarble.com/

Best of luck with your project. Please let us know if you have any other questions. Thank you for visiting our Houzz page.
