Fascinated by public sanitation? This 90min tour is a walk through the history and politics of London, as represented by the humble loo – and toilet humour is positively encouraged. Walks on Tuesdays, Thursdays and Saturday afternoons begin at Waterloo station, by the toilets opposite Platform 18, and are an adults-only activity (you'll drop in to some cocktail bars en route). Saturday tours of Bloomsbury start at Euston Square station at 11am. Advanced booking is strongly recommended.
