A residential layout featuring a toilet and sink, in addition to a full bathroomwhich includes a toilet, sink, and either a shower or bathtubis commonly referred to as having a one-and-a-half bath configuration. This setup generally offers more convenience than a single bathroom, particularly in homes with multiple occupants. An example would be a house with a full bathroom upstairs and a smaller powder room on the main floor.
The inclusion of an extra, smaller bathroom space can substantially enhance a home’s value and functionality. It reduces congestion during peak usage times and provides added privacy for residents and guests. Historically, such bathroom configurations have become increasingly popular in new construction and renovations as living standards and expectations for comfort have evolved.
