G'day, we're replacing a toilet suite in a late 60's house in Sydney. It currently has a ~6"(??) cast iron waste with a 230 mm set out. Firstly, does anyone know of any close coupled/BTW style suites that can handle such a large (S trap) set out? Obviously that's a more contemporary and cleaner look, but from what I've ben able to find it looks like a connector style only would be available with that set out. The floor has not yet been retiled, so it's certainly possible to replace the cast iron with PVC by punching up through the floor at lesser set out and plumbing that into the gully, but that changes the job from 1 hour to 1 day (at least)!! ie PIA factor is big.
HOWEVER part 2 of the question relates to plumbing into that cast iron using a pan collar. The current trap is exposed and mortared into the cast iron, easy-peasy if we wanted to replace with a retro style pan. I'm just not sure how to tackle a skirted pan and wondered what adaptors are available for the cast iron where I also won't have access to the trap outlet when bedding the pan?
Hopefully that's all clear, and thanks in anticipation.
Edit: On further thought, would it be possible to cut the soil pipe flush with the existing floor and use an offset pan collar to bring it back toward the wall? It would need to go back around 80 mm. Just not sure how to couple the pan collar to the cast iron???
