sorry but do you mean the Vitra range by grespania or is Vitra the make? These tiles were bought about 6 years ago. My problem is that water has got behind the tiles and the wall is made of strammit board (straw). Damp has penetrated to the bedroom next door, covered in foul smelling black mould.We have removed the affected tiles, but cannot get rid of the smell, even though the wall has dried out, it has swollen. Realizing this is something we cannot put right ourselves, the insurance company are coming this week, and I guess the wall will need to come down. The border goes all the way round the bathroom. As an alternative is there such a thing as a splashback. I have enclosed a picture of the damage. Any advice would be great as I do not want the whole bathroom re tiling if it is possible to make the one wall look ok. Thanks Julie
