Questions & Answers about После душа стоит вытереть пол в ванной.
Because после requires the genitive case.
- душ = nominative singular
- душа = genitive singular
So после душа means after the shower / after showering.
This is a very common pattern:
- после работы = after work
- после урока = after the lesson
- после фильма = after the movie
In normal usage, it usually means after showering.
Russian often uses a noun phrase where English might prefer a verb phrase. So instead of saying something like after taking a shower, Russian can simply say после душа.
In this sentence, the natural interpretation is:
- after someone has taken a shower
not:
- after some shower fixture in a room
Context makes that clear.
