Walking down the jet bridge my crew and I were met by the inbound crew who informed us that the aircraft did not have running water in both main cabin bathrooms. They were informed by Maintenance that the aircraft was to be taken out of service when it reached ZZZ; so they were surprised to see the flight going immediately back out. In light of the recent spread of COVID-19; I was concerned and uncomfortable to be working on an aircraft in which main cabin passengers would not be able to wash their hands. I informed the Captain and the Gate Supervisor that we were uncomfortable with this situation. Supervisor informed me she was calling the Tower and also asked the cleaners to bring hand sanitizer. No one attempted to discuss the situation any further with me; and boarding began. We departed for ZZZ1 with one working sink. While I understand on-time performance is very important; I think protecting customers and crewmembers should be of higher priority. We've been told repeatedly that the best thing to prevent the spread of COVID-19 is to wash your hands with soap and water. The water should have been fixed; or another aircraft should have been substituted.
Flight Attendant reported the aircraft departed with one working lavatory sink which impacted the ability of crew and passengers to wash their hands to help prevent the spread of COVID-19.
