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.
I was not able to find the tile I wanted (1"x4" herringbone marble) in any local tile reseller. My contractor actually suggested if I wanted to get the tile I would need to find it on my own. I was extremely nervous ordering such a large quantity from an unknown (to me) on-line store. I had no problems with ordering and we didn't have one piece damaged in shipment.
