The term "comfort station" is an antiquated term used to refer to a public restroom or bathroom. There are several synonyms and phrases that can be used in place of this old-fashioned term. Some of these include "restroom," "lavatory," "public facilities," "bathroom," and "washroom." Other less formal synonyms include "loo," "john," "WC," and "powder room." It's important to keep in mind the audience and setting when choosing which synonym to use. A more formal setting, such as a workplace or public event, may require more formal language when referring to public restrooms. However, in a casual setting, more informal terms may be perfectly appropriate.
