At home we call it the toilet. Well that's what it is and I don't really like the word loo. In a public place would use the term ladies/gents.
At secondary school I think every one called it the bog.
I remember visiting my grandparents who lived in terrace housing with toilets in the yard. Every one there called it the lavvy but mum and grandma told us children to call it the WC.
