What does loo mean?
“Loo” is an informal British word for a toilet or lavatory. It is used especially for the toilet in a house, workplace, school, restaurant, or other building, and is often more conversational than the more formal terms toilet, lavatory, and WC. Expressions such as “go to the loo” are particularly natural in everyday British speech. Although chiefly associated with Britain, the word is also common in Australia, New Zealand, and other Commonwealth varieties. American speakers usually understand it, but they generally prefer restroom, bathroom, or toilet. Its simple, direct sound and strong everyday character make it a useful example of the way formal vocabulary and colloquial vocabulary coexist in modern English.

Where does loo come from?
The exact origin of “loo” is uncertain. It became established in British English as an informal name for a lavatory, and its development is associated with the wider history of euphemistic and abbreviated vocabulary for the toilet. Unlike many standard English words, it does not have a securely documented classical or ancient-language origin.
How loo is actually used
Informal and generally avoided in formal or highly formal writing. In British English it is casual but widely accepted; in American English it is understood but much less common, with toilet, restroom, and bathroom preferred.
