A master bedroom typically refers to the largest and most luxurious bedroom in a house or apartment. It is usually designated for the use of the homeowner or primary occupant of the residence. The master bedroom is often more spacious than other bedrooms and may include additional amenities such as an attached bathroom, a walk-in closet, a sitting area, or other features that provide comfort and privacy to the occupants. The term “master” implies that this bedroom is considered the primary or superior bedroom in the dwelling.
