My new girlfriend just bought a place (hell I might make this my own thread). I saw it for the first time. I noticed the two showers have this lego like modular ceiling.
My concern is moisture or water going in the gap.
I have never seen anything like this and it could be nothing. But should I plug the gap with some sort of sealant..? Is this normal..?
