10 x square white bathroom tiles (Stotfold SG5)

Hi all. Does anyone have 10 square, white, bathroom tiles that they don't want? He has swapped our shower out, because the old one kept getting blocked up, as we can't get spares. Can't really take some of the old bits out of the wall without leaving holes. The rest of the tiles are imperial and new ones are too small. 152mm x 152mm will fit nicely. I have found packs online but don't need 48 of them. Thank you all.
