‘水桶’ (shuǐ tǒng) literally combines ‘水’ (shuǐ), meaning ‘water’, and ‘桶’ (tǒng), meaning ‘bucket’ or ‘pail’. Together, it refers specifically to a container designed for carrying or holding water — typically made of plastic, metal, or wood, with a handle and open top. It’s a common household and agricultural item in China, used for fetching water from wells, cleaning floors, watering plants, or storing liquids.

While ‘桶’ alone can refer to any kind of bucket (e.g., oil桶, paint桶), adding ‘水’ specifies its primary function: holding or transporting water. In modern urban life, water buckets are less common due to piped water, but they remain widely used in rural areas, construction sites, and emergency contexts (e.g., during power outages affecting pumps). The word is neutral in register — appropriate in both spoken and written Chinese — and appears frequently in everyday instructions, stories, and practical descriptions.
