Kerdi Line by Schluter Systems - Linear shower drain in either stainless steel or matching tile for a nearly invisible drain. Perfect for Open-Concept showers w/ no door. (http://www.schluter.com/7957.aspx)
modern small bathroom - I love that there's no ledge separating the shower floor from the rest of the bathroom floor, and I think I see a linear drain along the shower glass. I love it so much. Floor big tiles.
