I like the mix of marble and Ceramic

Calacatta 1x1 Hexagon Use the Calacatta 1×1″ Hexagon honed or polished $17.95 a Square Foot and Free Shipping (thru March 2016) and then a classic 3×6″ Ceramic on the wall which we have for $2.95SF and Free Shipping. I love the simplicity, you can really go with honed or polished on the floor, it is the grout that provides the traction (or friction coefficient if we want to use the real name) not the stone, big misconception.  Go with what you want.
