Eggleston Farkas Architects It looks like it might be the Leaf sink by Kohler: http://www.us.kohler.com/us/Leaf™-vessels-above-counter-bathroom-sink/productDetail/Above-counter-Sinks/426621.htm

or this - http://tiledaily.com/2011/12/09/rustic-brown-porcelain-tile/

A great looking wood porcelain tile would also offer a similar look, here's one from the same people - http://tiledaily.com/2011/09/28/wood-porcelain-tiles/

Sun Design Remodeling Specialists, Inc. It is from Mosaic Tile Co. - MTC Clay Workshop WS05

You may want to give them a call to see if they would sell/ship it to you directly. If not, ask them what distributor(s) does Mosaic work with in your local area. If they don't have the answer, likely your local tile installers will have the answer.

fresco Thank you!!
