But on the topic
I dare say that anthracite/gray and 30/60 have been around for so long that you can't really say it will still last for another 10 years as something people like.
Personally, I gave up on anthracite for the floors in our house build 7 years ago, also because I find it too sensitive.
If you look at comfort apartments that were built 10 years ago, anthracite on the floor combined with white tiles on the walls dominates the market. When I look at newer bathrooms, I feel that beige/natural or light concrete gray has replaced anthracite. Or also a warm wood tone. Compared to that, the anthracite/white combination does not look miserable, but rather ordinary and no longer up-to-date.
