I have no where for the transformer to go, it won’t have an 3point isolation point. It will be straight from light fitting and will come off once the light is off. There is no way to get a 3core from switch without destroying the room. It’s a flat roofed , no access from above the room, joists run across meaning a big strip would need to be taking out of ceiling along with a chase down the wall to the switch. So going from the light fitting to the fan is only way without destroying my house. The fan is at opposite side of bath, so about 1m from shower and about 1.5m from bath bowl.
