I never thought I’d see the day where we use a tile that is literally peel-and-stick, but these Stainless tiles from Aspect save you from all the hassles of backerboard, thinset and grout.  They are sold in a 3×6 subway tile size, and can be purchased in either long or short grain (the direction of the brushed finish). By mixing long and short grain you can create patterns without changing the material.  They are available in four different finishes: 1) brushed bronze 2) copper 3) champagne or 4) stainless.  According to the manufacturer, they are made of 60% recycled material and 99% of the manufacturing waste is recycled.
