Toilet waste pipe location

[britishboy7]

Our toilet waste pipe currently runs about 5" parralel along an internal wall from outside, then a 90 degree elbow into the back of a very dated back to wall toilet, hidden by an old unit that incorporates the cistern.

We want to fit a modern, close-coupled toilet that sits right back to the wall, obviously be buying one with a side exit for the waste pipe, but most cutouts are only give 1" or 2" extra.

Is there any way around this, without needing to build a 3" or 4" deep false wall to allow the toilet to sit right back??

?

Not quite sure what you describe but the internal wall, what's behind it ? Maybe pics. of WC and soil pipe ( and the vertical boxing over pipe)

The internal wall (the one on right hand side of the image) is a solid wall (1930's build), only thin and behind it is a recently plastered bedroom. In this photo, as you look at it, the waste comes out the back of the toilet and out the external wall directly under the bottle of bleach and windowvac

I want to do away with all of that and fit a new, close coupled toilet right back to the tiled internal wall (basically push the current toilet position right back), but the waste pipe exits the external wall too far forward (about a 4" gap betweeen it and the internal wall)

Hope attaching the image works

Thanks for the photo . It's a difficult one to achieve as you suspect, without a false wall. Of course if it was sitting where the cardboard box is the soil pipe could go straight out the wall - but that would probably mean a new soil pipe ( assuming it's iron ) Not an easy one to solve, other than your false wall , as far as I can see.

Might be doable. Is it being pushed back in the existing place on that existing internal wall? Here’s what you need to do: measure existing from wall to centre of soil pipe, and compare this to the one you want to purchase.

One of these might get you a bit of extra space

OP,
If thats not the only WC in the house, & you dont have six kids then why not remove it all except for the soil pipe arm?
Then take pics of inside and outside and post here?
You would be left with the soil pipe arm, the basin waste, and the cold supply exposed in the room.

What might be an option is, as suggested above, swinging the new WC around to allow it to sit back against the outside wall with the cistern just below the window "board".

But without seeing the position and connection to the soil stack outside i find it difficult to advise you further.

note: before doing anything, make sure you have everything you might need on site - or at least know where you can still get stuff.
