A bathroom is called a bathroom in Ireland. What is meant when you say "Bathroom" in Ireland is a room that has a bath. In some countries, it can mean a room that does not have a bath, but does have a toilet. Some countries are a bit uncomfortable about using the word toilet and so they use the word bathroom even when it does not have a bath in it. There is no problem about using the word toilet in Ireland, so a room without a bath, but with a toilet in Ireland is called a toilet. In Ireland, calling a room a bathroom when it does not have a bath in it, does not make sense. If there is a bath and a toilet in the room, then it is called a bathroom. Even then, someone might say they are going to the toilet, when their intention is to relieve themselves.
