Croma Design Inc Hi Kristen,
The tiles on the wall are 1" x 4" stacked 'Milky Way White' marble in tumbled finish. They are available at Olympia Tile http://www.olympiatile.com/products/natural_stone/marble/milky_way_white.html

Kristen Lee Thanks, you do nice work.

azhome I love the color scheme, so elegant and modern. What type of stone did you use on the floor. Looks like limestone. Please advice and color and source. Thanks!

Croma Design Inc Thank you! The floor is actually polished concrete, it was existing in the loft space.
