In America, you'll often hear the toilet referred to as the 'restroom'. This alternative word for toilet first gained popular usage in the early twentieth century.
In American English, the most common term for a private toilet is "bathroom", regardless of whether a bathtub or shower is present.
In Canada and the US it is impolite to use the word toilet. You can call the actual physical thing a toilet, but if you want to say that you need to use the toilet, you must say something else. We have all sorts of other polite names for it!
Public toilets are known by many other names depending on the country. Examples are: restroom, bathroom, men's room, women's room, powder room in the US, washroom in Canada, and toilets, lavatories, water closet (W.C.), ladies and gents in Europe.
Americans typically say bathroom for home facilities; public ones are usually restrooms; in high school we had to call it the lavatory, but you don't hear that much anymore. In the UK, the signs say Toilet; a colorful slang term in Ireland and the UK is the bog.
An outdoor toilet is a Dunny and an indoor toliet is called a loo.

The name “John” was later derived from “Jake” and “Jack.” Secondly but most notable amongst historians, John was the name of the first man credited with inventing the first flushing toilet.

As with many English words, some are common in American English and others are common in British English. However, words such as: bathroom, ladies room, men's room and restroom are common to both. On most airlines, the toilet is referred to as “the lavatory”.
Toilet. This was on the original 1950s list and, to be honest, I'd rather chew glass than use the word toilet in polite conversation. It's a harsh word that was adapted from the French toilette which means your appearance, hence toiletries bag. Lavatory or loo is much more acceptable.
Washroom: a polite word for bathroom. The Canadian version of “restroom.”
The American word is diaper.
Such rooms often had—or even may have been required to have—an attached room with a toilet. So if someone went to the rest-room, they might have also used the toilet or lavatory facilities, and that is what the word came to refer to.
Standard shower size Australia is most comparable with the average shower size in the US. There, shower dimensions are generally 36' x 36' – or 914mm x 914mm. In Europe, on the other hand, there is a great variety when it comes to the average shower size.
Dunny: If you eat Vegemite with every meal and have seen a few kangaroos in your lifetime, you'll refer to a movable toilet as a dunny. Australians usually call any toilet located outside a “dunny,” and a porta potty is no exception.
The dunny was originally any outside toilet. In cities and towns the pan-type dunny was emptied by the dunny man, who came round regularly with his dunny cart. Dunny can now be used for any toilet. The word comes from British dialect dunnekin meaning an 'earth closet, (outside) privy' from dung + ken 'house'.
A: It dates from the early 1800s, Scottish in origin, from dung + ken (house) to give “dunnekin” as another name for the outhouse. Once the toilet moved inside, Australians and New Zealanders dropped the kin and kept with the dunny.
bin. Avoid the use of the word garbage at all costs especially if you are trying to get children to throw something out, as you are giving them good reason to ignore you. You throw 'rubbish' out in the 'bin' in Australia.
'Lavatory' is a good option for people looking for a very formal word to use in very formal occasions.
New Zealand and Australia share many words. Dunny, a colloquial word for a toilet, is one of them.
