Hello,
I've been looking to buy a terraced house. In many of them, the
bathroom was originally downstairs behind the kitchen and over the
years, owners have converted a bedroom into a bathroom. I was thinking
it must be harder doing this work to a terraced house as you cannot
run any pipes along the side of the house (though with a semi detached
you only have access to one side).
I guess if the property had a front or back garden you could try and
install a new soil pipe but often terraced houses open straight onto
the street, which I guess means adding a soil pipe to the front is out
of the question.
Could you add a bath, basin, or shower to the front of the house if
the soil pipe was to the back? I am thinking that you could fit 40mm
waste pipe under floorboards if the joists ran the right way (front to
back but I guess they probably run side to side). But even if the
joists ran the right way, would you be able to get sufficient fall? If
the joists run the "wrong" way, I wouldn't feel keen on notching
joists.
At least 32mm or 40mm pipe is small enough to run under floors or
along walls. I'm guessing this isn't possible for 110mm pipe. Does
this mean that the only way to fit a toilet to the front of a terrace
house is to use a (dreaded) saniflo?
Thanks,
Stephen.

In terraced houses joists usually run from front to back, this avoids problems with party walls especially if they are only one brick thick as I mate of mine discovered when drilling into one only to go through into next door.

There would have been either an outside toilet, usually outside the kitchen,
or a privy at the bottom of the garden depending on the era.

Far more likely that there was no bathroom at all when originally built.

(Part H)
If your joists ran front to back:
The minimum slope of any drain inside is 18mm fall per metre (Dia 3,
Page 9 in the above doc).
So if you have about 5" to play with (50mm pipe in 8" joists) yoi have a
max run of about 7m.
In practise you can get away with a little less (I did) on 50mm pipe as
long as it is consistently falling (no "dips" that trap scunge) and you
have rodding access just in case. I'd say 10m is not really a problem
but it's not quite up to Part H.
So Bath/basin/shower no problem - there's plenty of fall available
assuming 8" joists. I would use 50mm pipe for the main run and include
an allowance to let it expand (uPVC does, a lot, when hot water goes
down it). This could be achieved where it does the 90 degree bend to
come up through the bathroom floor - allow that entry to be sloppy to
allow movement.
Toilet - you didn't mention, but I wouldn't. Less fall to play with and
you really do want a decent fall on soil pipe.
If your joists run counter, then you have really 2 solutions:
1) Sump+pump (like saniflo but less horrible). This is a standard
solution but it's not my favorite.
2) Drop 50mm pipe down through the ceiling and run it along the room
wall front to back. Box it in. This is actually a reasonably stadard
solution.

ceiling). I did not think of this as I was assuming a shower was
involved. It's just about possible to get the required fall (almost) for
a bath - I have one running above a solid floor).

macerator,which chops everything up and pumps it to wherever you want. You
can get one that fits right on the WC outletpipe.

Saniflo for many years. As long as you didn't put anything stupid down it
(like wet-wipes), it was trouble free.

Boxing in any other pipe work would be unobtrusive, soil pipe would be

much bigger but it's the only way, I don't mind doing that. What fall
does soil pipe need? The height of the outlet on the toilet isn't that
high to start with.

Thanks. I think I posted that question in reply to another poster
before I had read your reply. Next time I will read all new posts
before replying to any. 18mm/m is much less than I was expecting: I
was expecting much steeper angles, so it might be do-able after all.
Thanks again,

As I mentioned, if it were just bath water, you can use less (I think
mine is more like 10mm/m - BUT I would not use such a shallow run for a
toilet pipe and I'd be dubious using it for a basin or kitchen sink as
you get a lot of solid matter (toothpaste blobs, richards and food)
which can easily settle out in the middle and start an obstruction.
Because my soil pipe comes up through a solid ground floor, I could not
connect the bath to it (too low, major risk of back-flush) so I took
that "the long way" through the house to a grey-water-only 110mm drain
that serves the kitchen and a rear shower. The basin and the loo went
direct to the local foul pipe.

install an internal soil stack to the first floor to a new branch
under the ground floor. Take it either directly to a new inspection
chamber on the existing drain to the rear, or onto a new connection
onto the existing soil stack. The new stack will need to be
ventilated; either an open vent 900mm above the uppermost windows, or
an air-admittance (a.k.a., a "Durgo") valve.
If its not a joisted floor, the above could still be done but it would
involve digging up the ground floor slab.
