How do you say where is the toilet in french?

- Est-ce que je peux aller aux toilettes ?Pronounciation: (Es-seh-kuh jeh puh ah-lay Oh Twah-let) (the comonest way to ask it)

- Puis-je aller aux toilettes ? Pronounciation: (Pwee Ja-lay Oh Twah-let) (a bit aristocratic or affected)

- Est-ce que je peux aller à la salle de bains ?Pronounciation: (Es-seh-kuh jeh puh ah-lay ah la sal deh banh) (!! most French will think you're looking to wash your hands, but not that you want to go to the loo. Using 'toilettes' or 'WC', pronounced 'Veh-Ceh' is perfectly correct in French and will avoid confusion)
