Lavatory arrangement for an aircraft cabin with enclosed supplemental space partition provided in front of lavatory arrangement

A method for transforming a lavatory arrangement for an aircraft cabin, comprising the following steps:

• arranging a lavatory arrangement comprising a first lavatory compartment accessible from an aisle area via a first door, and a second lavatory compartment accessible from the aisle area via a second door;
• and
• moving a bi-functional partition wall arranged between the first lavatory compartment and the second lavatory compartment from a primary position, in which the bi-functional partition wall separates the first lavatory compartment from the second lavatory compartment, to a secondary position;
• wherein, to move the partition wall, the wall is released and then moved to provide the enlarged lavatory, and further placed in the aisle area where the partition wall is fixed;
• wherein in the secondary position, the bi-functional partition wall is brought into a position outside the first and second lavatory compartments;
• wherein, in the secondary position, the first lavatory compartment and the second lavatory compartment provide an enlarged common lavatory;
• and wherein in the secondary position, the bi-functional partition wall is arranged at least partly outside the lavatory arrangement and within the aisle area outside the first lavatory compartment and the second lavatory compartment.

A lavatory arrangement for an aircraft cabin, the arrangement comprising:

• a first lavatory compartment accessible from an aisle area via a first door;
• and
• a second lavatory compartment accessible from the aisle area via a second door;
• a divider wall arranged between the first lavatory compartment and the second lavatory compartment, comprising:
• a primary wall panel;
• a secondary wall panel;
• and
• a fitting assembly;
• wherein the primary wall panel is configured to be fixedly arranged between a first lavatory and a second lavatory of a double lavatory arrangement;
• wherein the secondary wall panel is configured to be removably arranged between the first and the second lavatory such that in an attached first position, the secondary wall panel and the primary wall panel provide a separation between the first and the second lavatory;
• wherein the secondary wall panel is movable to a detached second position outside the lavatory arrangement in which a separation of the first and the second lavatory is cancelled;
• and
• wherein the fitting assembly is configured to removably mount the secondary wall panel in the first position to at least one of the group comprising:
• a lavatory enclosure and the primary wall panel,
• wherein in the first position, the divider wall separates the first lavatory compartment from the second lavatory compartment;
• wherein in the second position, the secondary wall panel is brought outside the first and second lavatory compartments, in which second position the first lavatory compartment and the second lavatory compartment provide an enlarged common lavatory;
• wherein the secondary wall panel comprises at least two wall panel segments connected by a vertical hinge connection;
• and
• wherein, in the detached second position outside, the secondary wall panel is extracted from the aircraft lavatory arrangement folded along the vertical hinge connection and attached with a distal end of the secondary wall panel to a cabin wall structure arranged to the side of the first or the second lavatory such that a supplemental space section adjacent to the first or second door is provided, which supplemental space is provided as an enlargement to the enlarged common lavatory.
