Public toilets have many names in the UK. It's almost as if we are so embarrassed by their existence that we must cast about for a word or words that causes least offence. The most basic names identify them by the gender for whome they are intended, and "Unisex", as on these nautical-look beach front toilets at Weymouth, Dorset, is considerably less common than the widespread "Ladies" and "Gentlemen". For more on this subject, and a reasonably comprehensive list of UK toilet names, have a look at my post of 2006 on PhotoReflect entitled "What do you call it?"
