I am in the process of tiling in a boxed in bath,I am using plain white 6 inch x 6 inch tile. Where the front of the banth meets the top, what is the best way to finish the edge like here. I have got a bead but am not really happy with it but if I just butt the tiles up on 90 degrees angle the edge of the tile is not white. Any other ideas ? Soeey if I do not make sense.
