They’re probably shortening “bidet shower” to bidet.
Bidet showers are commonplace in Finland, in bathrooms pretty much for as long as I can remember. Aside from public toilets which nowadays do have them but used to be that like 1/5 stalls had them.
And I definitely don’t get off from the toilet to use my bidet shower. I feel like that would be horrendous for my bathroom floor.
Strongly recommended, yes. I know of no other way.
