Hahah so thats very interesting. We actually did a survey, posted it on instagram and sent it to a lot of friends both european and american, and bunch of different native language speakers, and the most surprising part was that spanish speakers from latin america generally preferred Lavabo and said it does not mean toilet just washbasin, but Spaniards all told me it can also mean a toilet haha. I prefer Earthbound, but the survey was 70% Lavabo : 30% Earthbound. There were some 100 responses more or less.
