If you need to use the toilet, you have to pay. It's a London quirk that spawned our tours. Rachel Erickson arrived in London from California in 2012 and was annoyed by this. So, she started seeking out places to pee for free. She racked up alot of toilet knowledge along the way and Loo Tours was born. Making connections with other ladies with a similar love of toilet trivia (and loathing to pay to pee), Loo Tours continues today. You'll be surprised at how much you will learn on a Loo Tour!
