What does lavabo mean?
A lavabo is principally a washbasin, traditionally one mounted on a wall and furnished with taps for washing the hands or face. In British English, it can also refer more broadly to a lavatory or restroom, although the word is now uncommon and may sound formal, institutional, or old-fashioned. Its name reflects its long history: lavabo entered English from Latin, where lavābō means “I wash.” The term is useful in architectural, historical, and descriptive contexts, especially when a more precise term such as washbasin, washstand, or restroom would sound more natural. Although still understood, it conveys an old-fashioned character and may suggest a communal washroom found in a school, workplace, or public building.
