"Sink" is the most common word used to refer to a "洗碗池" in Engpsh.

The word "sink" comes from the Middle Engpsh word "sinc" meaning a basin or container for holding water. Over time, the word evolved to refer specifically to a basin in a kitchen or bathroom used for washing dishes, hands, or other items.

Examples:

"I need to do the dishes and empty the sink." (我需要洗碗，清空洗碗池。)
"The sink is clogged and won't drain." (洗碗池堵塞了，排水不了。)
"Can you fill the sink with hot water for me?" (你能给我把洗碗池加满热水吗？)
