Waste pipes distance from a wall

[geoffdg]

Hi all,

Can anyone tell me what the distance from the wall to the centre of the waste pipes would be for wc (would probably be a close coupled), hand basin and sink. Just trying to figure out out to get the position right as they come up through the raft

 

Thanks,

Geoff

This is difficult to get right, I got mine fairly close. I asked the plasterer how thick his scim was, put the toilet together with waste pipe and did the maths. I did the same with basins etc.  Different toilet connectors have slightly different dimensions so get the kit together and measure it.

Around an inch off the finished wall usually I think. @Nickfromwales?

100mm to the centre assuming you are using board on dot and dab which adds ~25mm to the  blockwork.

Main thing is not to make it too close. If its a bit further out you can always batten the wall before plaster boarding.
