    Teacher's tip

    Learners should be aware that 'restroom' is the preferred polite term in the US, whereas 'toilet' can sound too direct or even slightly crude in social situations.

    Pitfall
    Where is the water closet? Where is the restroom?

    While 'water closet' (WC) is understood in some places, 'restroom' is the most natural and polite term to use in the United States.

From rest + room, from an earlier sense of "breakroom".
