Realistic costs for a single-family house?

Yes, there would probably be a tiny hole in it – neither deep nor wide. But the (sharp) knife has to hit just right first.

Do you have everything tiled?

On the ground floor and in the basement, yes, partly because they don't scratch as easily when you come in from the terrace and maybe have a little stone on your sole...

Well, you just have to like it – I see the risk of you scratching everything with sharp stones as quite low.

But yes, vinyl is more scratch-prone than tiles.

Well, you have to like it - I consider the risk quite low that you’ll scratch everything with sharp stones.

But yes, vinyl is more scratch-sensitive than tiles.

So in the last 2 years, 3 ceramic knives have already broken at the tip for me, they hit quite vertically.

Ok, that was a batch and one small chip per year is not the end of the world. Nevertheless, I find the almost indestructibility of tiles quite advantageous.

And all that happens in the living and dining room?

Twice I mean on the way from the dining area to the kitchen and once in the kitchen... But we are also somewhat straying from the actual question

The earlier PVC floors were simply great regarding knives (90s). Even if one was "stuck in" there, you just pulled it out, pressed a bit with your finger, and it was invisible again. Visually, they are of course no longer a hit, but for office or children's rooms, I still find them top. Absolutely water-resistant, easy to maintain, robust, and great to the touch. Today, this is partially replaced by cork or vinyl (which is just another term for PVC), but that has other disadvantages. The click vinyl floors are very robust and I would always prefer them to laminate and even parquet, but that's always a matter of taste. Tiles are obviously the most robust, provided you don't use porcelain stoneware. That can also be very sensitive, and you struggle with chipped corners. A disadvantage of tiles, in my opinion, is the temperature (really cold without underfloor heating) and that they generally last significantly longer than all other floors. Therefore, you should always choose something absolutely timeless here; otherwise, you might be unhappy after 10-15 years. With some craftsmanship, you can relatively quickly re-lay click floors yourself, and they only cost 50% of tiles, so you can change them twice as often. To each their own.
