Narrative:

Phase 1 (sent on landing in ZZZ they sent a supervisor to meet with us. Sprayed lavatory spray to mask smell; said we were good to go. Crew said we didn't think it was good idea to take this plane but they gave us the go ahead).this plane has been written up multiple times due to flooding in the back AC right lavatory (days ago). They cannot find the leak. The real problem is that it has flooded the carpet and made it a health issue. Everything nasty from the bathroom is being trapped in the carpet. This is a major health issue as it's flowed into the galleys where there's food. Passengers and crew are breathing in this stale air which is a health and safety issue. My sinuses were going crazy on takeoff and finally started to clear up as I was luckily working first class. Mechanics said it was not leaking though the carpet was wet and soiled. (Once again it was written up before today). If it leaves on the next leg it will not be fixed until at least tomorrow. This needs to be addressed before it becomes a bigger health issue. Phase 2 (sent after landing in ZZZZ). I know they mentioned the sink not shutting off; but the pilots said it had flooded before. Which; I believe as you don't get that kind of a smell from a first time leak. We reported the flight had made the flight attendants (all of us) feel sick on the way to ZZZ. They said they would shut off the water. We explained we didn't think that would help as the smell was coming from the soiled carpet. The solution they came up within ZZZ was just spraying lavatory spray on it. This actually made it worse. We then had to fly the plane to ZZZZ and once again the smell gave the crew headaches; sore throats; stuffy noses; itchy eyes (much worse than on the first leg). We explained this wasn't going to get fixed in ZZZZ. Now we are going to have to work this plane tomorrow. That's three times making us feel ill. Tomorrow will most likely be the worst as it will have been sitting overnight. We left early out of ZZZ because they didn't want to find us another plane and got into ZZZZ 45 minutes early. This needs to be fixed as it's a major health concern not only for the crew but the passengers as well. As we all know health and safety should always come first.phase 3 on this plane. (Supervisors stated they would have cleaners and others in ZZZZ try to get rid of the smell on aircraft before we arrived to take flight back next morning).they contacted ZZZZ officials don't know what they did (if anything). Flight was better due ZZZZ crew or the soiled carpet drying overnight. Crew was better off this leg.
