I am thinking about using the black coin pattern tile in a bathroom and laundry room. Can you see the interlocking edges once it is installed or do these disappear? Just trying to choose between the tile and a sheet product.

If you install one color, the interlocking edges will virtually disappear. They will still be visible in certain situations, but for the most part, the floor will appear seamless. If installing more than one color, the interlocking edges will show.
