These seating arrangements, prevalent in New Zealand, typically describe an interconnected bathroom shared between two bedrooms. The design commonly features a door from each bedroom into the bathroom, allowing direct access for occupants of both rooms without requiring passage through a hallway or other common area.
This configuration provides a balance between privacy and convenience, particularly well-suited for families or guest accommodations. It can offer cost savings by centralizing plumbing and reducing the overall footprint required for separate, individual bathrooms. Historically, such layouts were adopted to maximize space efficiency in residential construction.
