However, there are other words depending on the context:
* "W.C." (pronounced "doo-blay-see") is a more formal and less common way to say toilet.
* "Sanitário" is another formal word for toilet, often used in public places.
* "Casa de banho" (literally "bathroom house") is used in Portugal and some parts of Brazil.
* "Vazão" (literally "flow") is a slang term for toilet, especially in Brazil.
So, "banheiro" is the most common and safest option in most cases.
