I want to convert a fairly narrow room into a bathroom. It will have to
have a toilet and bidet opposite the washbasin, so to maximise the space
between I'd like a bog (and bidet) which doesn't extend too far into the
room. 500mm would be nice.
Simple! Use one with a high level cistern. Surely that means the bog
can be further back?
But from the ones I've seen, that doesn't make much difference. I'd
like to sit (typo?) with my back to the wall, and I don't want something
out of a doll's house or caravan.
We solved a similar problem by fitting a "back to wall" toilet
which only projects 480mm and "stealing" some space from the room on the
other side of the wall for a boxed in concealed cistern.
You need to be careful with choice of cistern to do this because the
cistern on the other side of the wall is fitted "back to front" compared
with the conventional arrangement. Some of these cisterns have a rigidly
fixed flush pipe which cannot be swung round towards the wall.
What about one of those posh Japanese toilets that have a bidet built
in with remote control, hot air blower, heated seats, etc. ?
(So only one unit rather than 2?)
My mother in law has one - it was installed when she had some wrist
issues (not sure exactly what it was, but she had an operation to fix it)
I've not used it but my wife likes it...
Further down this page is a humourous escapade involving expanding foam.
About 50 years ago a schoolchum of mine built a small sailing boat
(MiniSail) in his fathers garage.
Eventually comes the time to fill it with foam. Supplied by Strand Glass
Having read all the destructions the two parts are mixed, administered and
left to expand for whatever the stated period was.
After double that period nothing had appeared. So, whilst I shone a torch in
one of the filling holes, my mate Tony had a look in another. We hadn't
taken into account the coled temp that day.
You got it, at that moment the foam spewed from the hole like a hosepipe.
Fortunately he was wearing his specs but he was covered in the stuff from
head top to the waist. Of course he spun around so that his back got a good
dosing as well.
Hospital job. Cut his clothes off and shaved his head, eyebrows and eyelids.
Minor surgery to the nostrils.
Lucky he had his specs on otherwise he might have lost his sight. To this
day his hair and eyebrows look rather odd.
But we lived to tell the tale.
Thanks all for the input. This is on an outside wall, so 'back to the
wall' types aren't suitable. The best so far (including SWMBO approval)
is a high-level cistern type with the downpipe bend radius decreased,
which will get to about 580mm. I'd like a bit less ideally.
You can certainly trim the pre formed downpipe subject to not getting
too close to the bend - or make your own in plastic or copper with a
tight solvent weld/soldered bend.
However, with a rear facing spigot you are likely to only be able to get
the loo 2" further back than mine and that's still >4" out from the wall.
Following up to myself again.
Thanks for the thoughts again. The layout is such that the bog will be
opposite the washbasin across the 1700mm width of the room.
How much space between the two would I need without it being awkward or
looking very cramped? Are there regulations which apply?

It is a saniflo!! It does NOT have a proper grinder like Grundfos (better)
or Sanicubic, so has a miserable cutter & miserable starting torque. If Gru
ndfos would come out with a Grundfos compact toilet they have probably won.
The FRONT of the toilet will easily be 500mm, you might get to 480mm. That
is a GENUINE from the wall measurement, not from any rear partition to hide
pipework. With the front at 500mm, the rear of the ceramic is at 70mm and
pipework only extends a little into that area so it could be reduced furthe
r, non-concealed pipework allows you to shrink it right down or even elimin
ate it. You need a 300mm horizontal run from the sanicompact as I recall, h
ookup is via 3/4in BSP because I think it uses a washing machine solenoid v
alve to get around water reg restrictions - not the defacto 1/2in bsp that
every damn toilet uses. You might be able to get a custom hose made up if y
ou want a nice wall outlet rather than crappy washing machine hose or use a
3/4-to-15mm in-wall adapter and elbow etc.
If you run the saniflo mini soil pipe downwards outside (to a dedicated was
te stub stack) then you MUST either a) change to a larger diameter pipe to
break any syphon at same floor level as the Sanicompact or b) fit an AAV ca
pable of withstanding 10psi.
No manufacturer will rate any AAV to 10psi, the pressure a Sanicompact crea
tes against a blockage ... which would mean you know what will ERUPT from t
hat AAV inside any partition etc. So defacto BREAK the syphon by switching
to larger pipework.
Good thing about a Sanicompact is you can lift it up, encase in concrete an
d just go buy another. Do not send it to BNFL, they will not reprocess it,
send it back to France with no return address on it :-)
If you can use a Grundfos solution, they have proper grinders and SHOULD be
a world away in terms of actually engineered fit for idi^purpose.
Note that for a high level cistern, you need more resistance in the
flush pipe, or it empties into the pan too fast to go around the
U-bend, and you don't want that ;-)
This means you can use a narrower flush pipe than with a low level
cistern, and probably also a knuckle bend behind the pan. Maybe you
could even recess the knuckle bend into the wall.
With a modern pan designed for a 6 litre flush, and if you have a
good mains water flow rate, you might be able to rig something up
that flushes the pan direct from the mains, with no cisterm.

I would have to admit there is no restriction in my high level flush
pipe and it works fine - this pipe is about 40mm or the nearest standard
copper pipe size - I know because I have a standard pipe clip supporting it.
