Dual modular lavatory with alcoves

A method of assembling a dual modular lavatory monument assembly configured to be positioned in the interior of an aircraft, the method comprising the steps of:

• providing a first outer shell that includes first, second, third and fourth walls that cooperate to define an interior, and a fifth wall that divides the interior into first and second lavatories, wherein the outer shell includes first and second alcoves that extend between the first and second walls, wherein a first door is positioned on one of the first or third walls, and wherein a second door is positioned on one of the second or fourth walls,
• removably securing a first sink module in the first alcove,
• removably securing a first mirror module above the first sink module in the first alcove,
• removably securing a second sink module in the second alcove,
• removably securing a second mirror module above the second sink module in the second alcove,
• removably securing a first toilet module to one or more of the first, third, fourth or fifth walls, wherein the first toilet module does not contact the first sink module, and
• removably securing a second toilet module to one or more of the second, third, fourth or fifth walls, wherein the second toilet module does not contact the second sink module.

A dual lavatory monument assembly configured to be positioned in the interior of an aircraft, the lavatory monument assembly comprising:

• first, second, third and fourth walls that cooperate to form an outer shell that defines an interior, and a fifth wall that divides the interior into first and second lavatories, wherein the outer shell includes first and second alcoves that extend between the first and second walls to form an alcove strip, wherein the fifth wall includes first, second and third portions, wherein the first portion is connected to the first wall, the third portion is connected to the second wall, and the second portion extends between and is not parallel with the first and third portions, and wherein the first alcove is defined in the first lavatory between the first wall and the third portion of the fifth wall and the second alcove is defined in the second lavatory between the second wall and the third portion of the fifth wall,
• a first sink positioned in the first alcove,
• a first mirror positioned above the first sink in the first alcove,
• a first door positioned on one of the first or third walls,
• a second sink positioned in the second alcove,
• a second mirror positioned above the second sink in the second alcove,
• a second door positioned on one of the second or fourth walls, and
• a first toilet positioned adjacent the second wall and a second toilet positioned adjacent the first wall.
