So it turned out that the builders had 'mislaid' some of the tiles somewhere in the house and thought they'd run out. Of course the tiles turned up so we have some excess.
Thanks to a comment from my lovely Sister about the 'wipeability' of the downstairs loo we decided we needed something to the side of the loo, enter the mislaid tiles, which have also made the splashback.
Apologies for the crappy photos, my beloved Fujifilm camera has developed a problem with the lens cover so these were taken with my Blackberry camera.
