Kirstin Havnaer, Hearthstone Interior Design, LLC Hello!
All of the tile you see in that bathroom is travertine. It's a natural stone that comes in a few various shades of creamy white and beige. Let me know if you have any other questions!

T Williams Kirstin, Thank you for the prompt reply! Do you know the size of the mosaic on the floor as well as the size used on the walls of the shower. Is the same tile used for the floor? I have been looking at the travertines and they are all beige! do you know the specific colors and name/manufacture used in each location? Thanks,
Tracey

Kirstin Havnaer, Hearthstone Interior Design, LLC Hi, again.
So I dug out the file for this project and actually have to correct something I said. Part of the problem is that this project was done in 2006 and many of the tiles and/or distributors I used then are no longer around, but here are the details anyways:

Shower walls & ceiling - Lappato Abano porcelain tile (distributor I used has gone out of business, but perhaps an internet search might turn up another source). the tile looked very much like travertine but was smooth in texture.

Shower Floor - The central area and stripe around the outside was a 2x2 travertine mosaic in various shades. The white stripe in between those two is Botticino marble, which is very common.

Accent Tile on shower wall - Again, a travertine mosaic border with varying colors.

As far as the travertine colors go, look for "Durango" as the creamy color and "Noce" as the more brown color and you might have some success.

Hope that helps a little bit.
