Differences in tiles from the hardware store or tile center

Decorations were mentioned, their repetition/frequency, sorting (mixing of available sizes), surface texture, rectification/calibration for narrow joints, ... If we all this is not significant enough, then bring it up instead of playing the troll here.

If I knew, I would have informed the te.

Rectification was mentioned but not addressed! Are there different class groups or a measurement unit?

Are there breakage classes or how did you choose besides by appearance?

I'm not nitpicking, but here only wood-look tiles were discussed, so I only reacted to that. I want information about tile quality and how to recognize it.

Then just ask.
Basically, this is more about the difference of the (inexpensive) DIY store tile anyway

Qualities are abrasion classes, frost resistance, slip resistance levels, and all of these are also offered by inexpensive hardware store tiles at a level sufficient for private households. The weak point of a tiled floor is rather the grouting, which is relatively soft. Karsten
