  2. yùshì (浴室)
  3. xǐshǒujiān (洗手间) ✔

Why: Xǐshǒujiān (洗手间) literally means hand-washing room and is the polite public restroom term. Cèsuǒ (厕所) is plainer, while yùshì (浴室) is a shower or bath room.

Huh, didn't know that: You will also see wèishēngjiān (卫生间) on signs. It means bathroom or toilet too.

The dad joke
