I've just had my bathroom done by my plumber Dad and paid a lot of money for a very good tiler to do the tiling. However, after on returning to my bathroom I've discovered that the tiler has laid a tile right in the centre of the bathroom that looks like it's got a big white stain on it. I know the tiles have got some marbling on them but nowhere else has this big white splodge. I've left it a week and I still can't bear to look at it so it has to come up. My Dad is a half decent tiler but is not in the league of the person who did it originally but I'm looking for advice on how he can get it up without cracking any of the others and laying a new one at the same level as the tiles around it. It's getting to the point I can barely go in the bathroom as I can't look at the tile anymore and would rather rip up the whole floor and start again.
