I know the size of the area I want to tile. Calculate the number of tiles I need to order:
You need units. We recommend that you order units (10% extra) to cover cuts and future repairs.
Unfortunately this is not ideal to be used as a floor tile as advertised. It is extremely soft. I did a black and white checker pattern, the white Grecian marble looks great, the black has a ton of marks and scratches after only 2 weeks of extremely light residential use. My $10k job looks ready to be redone already. For a wall - I imagine this marble would be fine.
I am very happy how the marble tiles were packaged; unlike ones I got from Home Depot, none were broken or damaged. All were good! quality marble; I used in the bathroom, entry, and fireplace. I will order some more!
