En Suite
When a bedroom contains a bathroom, it's considered en suite
“En suite" is a term used in home design to indicate that there is a bathroom within the bedroom. It is French term, meaning the bathoom and bedroom form a set. In other uses it can refer to anything that is in a sequence or is part of a set or series.
In the days when most travelers shared baths down the hall in a hostel, en suite bathrooms were the height of luxury and privacy.
It requires only space and plumbing to create an en suite bathroom.
Depending on how much privacy is needed, the en suite bathroom does not necessarily require walls.
Privacy can be as simple as frosted glass, allowing the room to feel larger and letting in natural light.
A partition behind the headboard creates a perfect separation for an en suite bath.
