How many bathrooms are in an airplane?

The number of bathrooms on an airplane varies depending on its size and configuration. Smaller regional jets may have one or two bathrooms, while larger commercial aircraft, such as the Boeing 777 or Airbus A380, can have multiple bathrooms, often ranging from 4 to 10. Additionally, some planes may have dedicated crew rest areas with their own facilities. Overall, the specific count can differ significantly based on the airline and aircraft model.
