I would be grateful if anyone can shed any light on this.
3 and a half years ago I had a full bathroom refit, tiles, bath etc. On the wall where the longest side of my bath sits, we had to tile on existing tiles - everything sound and secure. No pipeworks behind, leaks etc.
The tiles we used were a ceramic tile, with a slight glaze - beige color.
Everything seemed well until last night.
When turning the light of, I noticed only one tile closest to the bath rim, had a dark mark, size of my palm of my hand, underneath was another dark patch, roughly the size of a finger. Never noticed this before. Tried wiping the tile, it is still there. Grout, and sealant seem good. Never noticed this before, but this is only on one tile?
Any ideas what this could be? It certainly is noticable.
