Concealed toilet unit and soil pipe

[CAESAR32]

I have a concealed toilet unit with a depth of 220mm I need to drill to bring the soil pipe in to the room at a right angle to it. Do I do this so the pipe will come through the middle of the unit or further back?

This is the layout

I'd go further back, just to give yourself more space to work with.

Thank have brought it in so when plasterboarded and tiled, the back of the 110mm pipe will be about 25/30mm from the finish wall

Does that sound okish?

 

[denso13]

Yea, sounds ok.
