A friend of mine wants to change his cloakroom toilet into a shower.
The existing toilet pan waste exits vertically downwards into the
floor, in almost exactly the same place I'd be fitting the shower
tray. Which is handy.
Once I remove the toilet and it's pipe work I am left with the mouth
of the sewer at floor level - like a big round hole in the floor. It's
an old ceramic waste. So if you can imagine it, I'm left with the
mouth of a waste pipe pointing straight up, at floor level.
As it happens, it's almost exactly where then shower trap will exit -
so my question is, whats the best way to interface the shower trap to
the existing waste pipe?
You can get a soil pipe to <various smaller> converter - looks like a flat
end plug with a single small socket in the top, offset from centre. Quite
slim. unfortunately screwfix don't do one, so you may need to hunt around.
I can't remember if it was more of a plug (pushes into the pipe, which would
be ideal for you) or a cap (soil pipe goes into it) which would require you
to adapt it in, probably making it too proud of the floor.
Anyway, from the side it looks like this:

Fit an old-fashioned French squat WC tray? ;-)
BSF, problem if the new shower waste is too close to the soil pipe is that
you can't fit any sort of trap with a side exit (because the exit needs to
be underneath the trap, not to the side). I'd be thinking in terms of
those traps where there's a dip tube that can be removed from the top of
the trap (i.e. from the tray, when all installed) and the trap body is a
sort of sump. The tube forms a trap when it's inserted but when removed you
can clean the sump out. I'd be thinking of constructing a sump out of
solvent-weld pipe and fittings of a bore intermediate between the soil
pipe i/d and the dip tube o/d (e.g. 40, 50 or 67mm) that would seal to the
base of the shower tray and to the soil pipe. Difficulty would be
assembling and sealing it all, whilst laying the tray.
Possibly a constructed tray, a la wet room (or even a full wet room) might
be easier to engineer.

Yes that's a possibility that had crossed my mind.
I thought there would be a 'waste reducer' such as the poster above
mentioned, but I can't find one anywhere.
It's looking like I'll use a low profile trap and some concoction to
seal it's output to the soil pipe.
How about if the OP uses one of those traps and then fit an elbow from
the output straight down into the soil pipe hole. Or to be really
cheap, lash up an 's' bend with 4 elbows! Have seen that done with a
condensate outlet before.
