Unidentified leak from bathroom into living room

Hello I wondered if someone could explain why a leak would come and go over time and also create stains on the ceiling in different spaces really far apart from each other. There is a leak coming from the bathroom, behind the shower area and leaving stains on the ceiling in the living room. Each time we've noticed a patch we've had a plumber come in, and he's temporarily fixed the issue but it's come back eventually. The first repair solved it for about a year, then it started again with small dark spots appearing - if you can imagine a space of around 60 cm and within it, there are about 7 circles, all far apart from each other which I can't understand - why isn't it just one big patch? Our plumber came in again, and then put more filler behind the shower. There was no more visible leaking for 5 weeks, and then it started again, with the same patches getting wider and darker. there are now also a few new spots, very small and again, away from the other ones. The plumber has told us to order a new rim for under the shower screen which he will fit. I am concerned this would be another temporary measure as he didn't spot this as an issue when he came in January. Is there a way to fix this once and for all. How do I know for sure that a plumber is fixing this the best they can and not incurring further jobs - very concerned about how this is getting worse and I'm not sure what to do or how to identify the true cause. thank you
