One of the most useful things you can learn in English language is how to ask for the toilet! As they say, when you gotta go, you gotta go. You have always been confused by the terms washroom, restroom, bathroom, lavatory, toilet and toilet room. I guess the difference here is not only in different kinds of English words, but also in whether one is referring to a room in their house or in some public place.
The flush toilet,
The most common type of toilet found, sends waste through a series of pipes that lead to a sewer system and eventually a waste treatment plant or septic tank.
Common in Turkish and Japanese households, this toilet looks like a porcelain hole in the floor that individuals have to hover over, with their knees bent in a squat position.
Lavatory / Toilet –
A room equipped with washing and often toilet facilities.
Loo / Bog –
The word ‘loo’ is quite polite and is a slang.
Khazi/ Latrines –
Khazi is military expressions and ‘latrines’ sound more polite and suggest a block of toilets constructed together.
Crapper – ‘crapper’ sounds a little rude but it was actually the name of the man who invented the flush toilet mechanism, Thomas Crapper.
‘Throne room’ is a little ironic with its associations with royalty.
Washroom / Bathroom / Restroom – Another word for toilet.
