  • Aircraft Lavatory Unit and Structure for Arranging Same
    Publication number: 20150129717
    Abstract: Provided are an aircraft lavatory unit and a structure for arranging the same. A space section of a uniform width extends in a straight line from a rear wall to a front wall between a first side wall and a second side wall. A toilet bowl is disposed near the end in the extending direction of the space section on a side with the rear wall. A storage box is disposed above the toilet bowl between the toilet bowl and the rear wall. A wash basin is provided on a top surface of the storage box. The width of the body frame where the second side wall is located is formed at the minimum dimensions sufficient to ensure that the space section is wide enough that a person can come and go between the doorway and the toilet bowl and sit on the toilet bowl.
