What is a Bathroom Called on a Plane?

On a plane, a bathroom is commonly called a lavatory.

According to the reference provided, an aircraft lavatory or plane toilet is described as a small unisex room equipped with a toilet and a sink. These terms are the official and most frequently used names in the aviation industry.

Understanding the Terminology

While people often informally refer to it as a "bathroom" or "restroom," the correct and technical term used by airlines and aircraft manufacturers is lavatory. This term distinguishes it from larger, multi-stall bathrooms found in buildings.

• Lavatory: The standard and formal name.
• Plane Toilet: A more descriptive, informal term also used.
• Bathroom/Restroom: Colloquial terms used by passengers.

Key Features of an Aircraft Lavatory

Aircraft lavatories are designed to be compact and efficient spaces within the limited area of a plane.

Here are some common features:

• Toilet: Often uses a vacuum system for flushing.
• Sink: Usually with a small faucet and hand soap.
• Mirror: Typically located above the sink.
• Trash Receptacle: For disposing of waste.
• Call Button: To alert cabin crew in case of need.
• Lock: To ensure privacy during use.

Understanding the proper terminology like aircraft lavatory helps in navigating airport and airline information, although cabin crew and signage usually make the function clear regardless of the term used.
