I need to remove two tiles from my bathroom to do some pipework. I am hoping to get the tiles out in one piece. These tiles are discontinued. We got them from Wickes a number of years ago. The size is 350 x 230mm. They are gloss white with a slight dimple. the backing is terracotta. Only got a few slivers of tiles left in my shed. Really don't want to change tiles as they are on all walls floor to ceiling.
