Really don't need a combined light and extractor opening. A product created for the sake of creating somethingVery kind of you, I'm not in the UK for a couple of weeks but if you still have them when I get back, I might take them off your hands.
I didn't realise you could get those, I thought they all came as part of a ceiling extractor fan. Will look into that thanks. Think someone previously suggested something similar above and it went over my head, if they meant the same thing.

Ahhh ok, similarish type sealing system. I like a big seal behind the the tray to the tile backer board on the wall, then you have the tile over the surface of the tray that's the siliconed as normal. Uber belt and braces with these systems.Ha yes I think I've watched all of Roger Bisby's relating to bathrooms. They're very good.
I got an Abacus No More Leaks shower sealing kit from Rubber Duck. I preferred it to the classiseal because from what I can tell, it forms an upstand rather than going behind the tray, which I thought sounded better.
Also got a full tanking kit with tape etc. from Nassboard.
Just found out my floor dips 24mm over the course of the 1.4m tray, so I'm going to sister on some 6x2" joists to the older ones to give me my new levels to attach the subfloor to. The rest of the floor will be left to dip down gradually as getting it level across the 3.6 length is just silly IMO.
