It is a rather formal, slightly old-fashioned word. In everyday talk many people just say waiting room, lobby, or hallway, and that is usually fine.

It is a rather formal, slightly old-fashioned word這是一個蠻正式、有點過時的詞。In everyday talk平常講話 many people just say waiting room, lobby, or hallway很多人就直接說 waiting room（等候室）、lobby（大廳）或 hallway（走廊）， and that is usually fine這樣講通常沒問題。

Though actually, an anteroom is not only for waiting: it can simply be the little room you pass through to reach the big one, like a front room in an old house or a palace. You will meet it more in books and in descriptions of official places than in casual chat.
