- These are all terms for a room containing a toilet, and often a sink. Usage varies significantly based on region, formality, and context (public vs. private).
Explanation
Origin
- Restroom (US): Public context, euphemism suggesting rest/refreshment.
- Bathroom (US/Can): Common in homes, derived from rooms containing a bathtub, now often used even if no bath is present.
- Loo (UK/Commonwealth): Informal, origin debated (possibly French 'lieu d'aisance' place of ease, 'l'eau' water, or 'gardyloo' warning cry before emptying chamber pots).
- Bog (UK/Ire/Aus/NZ): Very informal slang, from 'boghouse' (an old term for an outhouse, possibly related to peat bogs where waste might be dumped).
- The can (US): Informal slang, likely from the historical use of cans/pots as chamber pots before widespread plumbing.
- Crapper (US/UK): Vulgar slang. Often linked to Thomas Crapper, an English plumber who manufactured toilets, but the term 'crap' (defecate) predates him. His name likely reinforced the association.
- Dunny (Aus/NZ): Informal slang, originally for an outside toilet (outhouse), possibly from 'dunnekin' (old dialect word for earth closet). Now often used for any toilet.
- Powder room (US): Euphemism for a guest toilet in a home (usually just toilet and sink), historically referencing women retouching makeup ('powdering their nose').
- Little boys'/girls' room: Gentle euphemism, often used when speaking to or about children, or humorously by adults.
- The facilities (Formal): General, polite euphemism used often in public announcements or buildings.
- Hit the head (US): Naval/military slang. The 'head' of a ship (the bow) was traditionally where the crew's toilets were located, downwind.

Misunderstanding Warnings
- Using Bathroom in the UK might specifically imply a room *with a bath*, although US usage is becoming more common. Stick to loo or toilet for clarity.
- Using slang (bog, crapper, can) in inappropriate settings can cause offense or appear rude.
- Toilet refers primarily to the fixture in the US, but commonly means the room in UK/Aus/NZ. Where is the toilet? is standard in the UK, but might sound slightly blunt or overly direct to some US ears expecting restroom or bathroom.
