In German Culture, does the concept of a Master Bedroom, exist? In America, most houses have a master bedroom that is constructed differently than the others, and is usually identified as such on the building plans. It is usually the largest bedroom, and many times will have special construction considerations, such as it's own bathroom, bigger closets, restricted access, etc.
Yes and no.
No, because we don't count bedrooms but "all-purpose-rooms" excluding kitchen and bathroom. You will find terms like
meaning three rooms that could either be used as three separate bedrooms (like with college students sharing a flat), bedroom, guest room, office... whatever combination comes to mind or fits the life of the inhabitants.
Yes, because of course the main inhabitant(s) (or parents, for example) need their bedroom. But you wouldn't use a literal translation, instead it would be called
- Elternschlafzimmer (in case of parents) or simply
- Schlafzimmer (generic term).
Non-Master bedrooms on the other hand are typically specified in detail, either as
- Kinderzimmer (yes, often even if said child is 25 years old),
- Gästezimmer (for guests)
- zweites (drittes / ...) Schlafzimmer (e.g. in case of a couple having separate bedrooms or a shared flat)
- [Name of occupant]s Zimmer (if the child mentioned above rejects the term "Kinderzimmer")
