I noticed this morning that the brand new shower I just had installed has a few tiles with strange faint grey circular marks in them. Very hard to see but it's pissed me off. Anyone any idea why this is.
Wrong type of adhesive staining the porcelain? I know it can happen with natural stone and I've never seen it on tiles but that would be my first guess. Maybe slightly porous tiles/fault with the glaze?
