Tell me please if used the phrase correctly in the following context.
Person 1: How is this bottle called in English?
Person 2: Water bottle
Person 1: and that is all?
What I want to convey by that phrase is that person 1 is surprised by the fact that the bottle is simply called a water bottle, and there is no any specific name to the bottle. I doubt that that phrase was right in that context. I just translated it word for word from my native language. Tell me please what is the natural way to convey the meaning in English.
