Really? I doubt that. Perhaps most buildings, as storey buildings do often have a shared sauna. As an anecdote, I have lived perhaps in 6 rented apartments, and two of them had a sauna, and I don't think I decidedly chose non-sauna option.

Here's some article in Finnish about the current trend that new apartments don't necessarily have a sauna: https://yle.fi/uutiset/3-9393813

It could be that most households have but also I've seen an article that people use them plainly as storage rooms.

And that YLE article about a trend change is after there was a recent-ish trend to start building saunas in apartments. So older apartments don't have saunas unless retrofitted, and newer ones are starting to be less likely to have them.

On the other hand, there's a lot of people like me too; one sauna in the basement, one smoke sauna a bit further away from the house (near a river), and a regular outdoor sauna in the yard. Sauna is serious business! :)

Yes, really.

Quick search gives 1.720 million saunas in apartments (total 2.3). So your claim sounds about right.
