One side of my gray bathroom (tub) wall needs repair. I cannot seem to find an exact match of gray 4X4 tile. My local tile store staff suggested gray/white glass mosaic tile to use:
1) as a narrow frame around the wall and fill the inside with white 4X4 tiles or
2) on the entire side of wall needing repair.
In both cases, the other two walls will have the same tile. Below are images of the wall that needs repair (with some white patchwork tiles) and the glass mosaic sample from the store. Help!
