Claim 12:
13. A method for converting an aircraft lavatory dimension from a first dimension to a second dimension, the method comprising:
altering an aircraft lavatory dimension of an expandable aircraft lavatory from an aircraft lavatory first footprint to an aircraft lavatory second footprint, said aircraft lavatory first footprint bounded by at least three aircraft lavatory first footprint wall sections, with at least two aircraft lavatory first footprint wall sections in communication with a movable expandable wall-door in a movable expandable wall-door wall configuration, said aircraft lavatory second footprint bounded by aircraft lavatory second footprint wall sections, one of said at least three aircraft lavatory second footprint wall section comprising a retractable barrier wall located proximate to an aircraft door bustle of an aircraft door, said movable expandable wall-door in the aircraft lavatory second footprint configured to abut an aircraft aisle, said movable expandable wall-door comprising at least one wall-door panel, said at least one wall-door panel having a first unexpanded door panel area in a stowed door panel configuration in the aircraft lavatory first footprint, said at least one wall-door panel having an expanded door panel area in a deployed door panel configuration in the aircraft lavatory second footprint;
disengaging the movable expandable wall-door from at least one first aircraft lavatory footprint area wall section;
engaging the movable expandable wall-door with at least one aircraft lavatory second footprint area wall section;
deploying the at least one wall-door panel from the first unexpanded door panel area in the stowed door panel configuration to the second expanded door panel area in the deployed door panel configuration; and
converting the aircraft lavatory first footprint into the aircraft lavatory second footprint.
