Annie Thornton Are you referring to the tile on the floor? It looks like a pretty standard marble basketweave pattern. Here is one by Ann Sacks. 1 1/2" x 3" and 9/16" x 9/16" on 14" x 14" netted sheet.
If bright pinks and purples are a little too heavy handed for you, you can still be bold with neutrals. A high arch of marble tiles seems to soar above this bathtub and mimics the arch of the window below. Note the size variations of the tile on the wall and ceiling, all different variations of Bianco Carrara marble.
