I've been to Germany, the Netherlands, Scandinavia, Spain and France. Only France had a few in touristy beach areas. The total low is Germany, where the whole country has only 1300 (given ~100 cities with >100k ppl, that is just a ridiculous 13 per large city): https://www.bmuv.de/pressemitteilung/staedte-und-gemeinden-m...

Amsterdam Schiphol Airport has drinking fountains at most if not all toilets[0]. There's been a short period recently apparently where they were getting replaced and so were unavailable.

The city of Amsterdam has 500 fountains or bottle filling stations[1]. The rest of the country has at least 2400 more[2].

You sure you checked all of Scandinavia?

Mostly Oslo and Stockholm.

Oslo airport has water fountains.

Thought to be fair I don’t think I’ve many in Oslo city.

I generally just ask a cafe to fill my water bottle if I need to. I’ve never had anyone refuse

Then write that.
