Say “OK Google” to activate the Assistant, say the command “Show me toilets near me” and it will open maps with placemarkers for all the toilets near your location. The feature also works inside Google Assistant. Google Maps will instantly show you the location of restrooms near your current location. Open the Google Maps on your phone (or open on your desktop browser), make sure that the location services are turned on and type the query public toilets near me.
If you are traveling in a new location, the public toilets and bathroom finder option avaialble inside Google Maps could come in very handy.
