But for some of us, admitting that, and allowing others to actually hear us doing so, fills us with fear.
Whether you have some kind of toilet-related issue, or just don't want strangers listening in on your bathroom antics, this app is here to save the day.
The Silent Loo app, which started off as an April Fools' joke invention, covers the sounds of you using the lavatory with every water-related sound from trickle to tsunami.
To mark this week's World Environment Day, Bathstore has released the fully functioning app for iPhone and Android, which you can now download for free.
Bathstore's research found 75 per cent of water used each year is from wasted activities like running the tap to disguise your loo noises.
So if you're up for saving your embarrassment and also the environment, download the app now!
