MODULAR LAVATORY WITH ALCOVES

A modular lavatory monument assembly configured to be positioned in the interior of an aircraft. The modular lavatory monument assembly includes first, second, third and fourth walls that cooperate to form an outer shell that defines a lavatory interior and a fifth wall that divides the interior into first and second lavatories, wherein the first and second walls oppose and are parallel to one another. The outer shell includes first and second alcoves that are at least partially defined by the fifth wall and extend between the first and second walls to form an alcove strip. The assembly also includes a sink module positioned in each alcove, a mirror module positioned above the sink module in each alcove, and doors positioned on one of the first or third walls, and on the second or fourth walls.
