While I'm familiar with the American usage of 'bathroom' to cover all
types of bathrooms/loos etc, whether or not they contain a bathtub, I
hadn't come across these niceties of 'full' and 'half' baths.

There's also a "Jack and Jill" bathroom, which is an en-suite shared
between two bedrooms.

There are other even weirder combinations too. My grandmother's place
has a main bathroom with doors opening into the living room and guest
bedroom, while the master bedroom has it's own full bath.
