Are there polygonal concrete slabs on the market?

I just noticed... At EHL, for example, there is something like this: "Polygono Naturale" is the series in 2 color variants.

But the pattern repeat is visible. I get eye strain when I think of the classic polygonal tiles. It is comparable to the wood-look tiles that show the same grain on every 6th tile. Those who don't know the polygonal tiles can probably live better with the stones.

I have often read that natural stone is supposed to be very sensitive.

You can impregnate or seal natural stone. Then it is no longer sensitive.
