What is the guarantee on a crack in a wall tile installed by a professional?

Questioner

How much guarantee do we have on a crack in a wall tile, if the tiling was done by a professional, 2.5 years ago in a new walk-in shower, which was also installed by this professional. They are large tiles, 60 x 30 cm. I think they are glued.

You can expect a certain period without these kinds of moisture problems, which however always rear their heads. Perhaps the professional has made a demonstrable mistake, but you can better have that assessed by another professional (preferably not in the same region). Furthermore, you can also distinguish between the consumer purchase of the tiles and the possibility that there is a defect in the tile at the time of purchase.
