Unfortunately, Metros are bang on trend again. I hate the damn things. Just did a small wetroom in them; white with antracite grout. Now this last week, I have a kitchen splashback with them with one end whole wall 9 ft high 7 ft wide, 6x3 bevelled black on the bottom, white on top, one row above the worktop black, above white with the black tiles having antracite grout and the whites above with silver grey grout. The black tiles being a different size to the whites just for good measure. If people are set on them, nothing seems to be able to change their minds. Hope you can get a better suggestion accepted. My wife nearly tried to choose them for our kitchen. I refused to lay them
We're now having 12x4 flat in an edwardian house, shaker style doors. I feel your pain.
cheers,
Stephen
