Moving a soil pipe to another room - anyone had this done?


Recommended Posts

I was told years ago that it would be prohibitively expensive to move a soil pipe, but I'm now rethinking.


I'm in a small mid-terrace, 2/3 beds.


At present, my rooms are in a weird configuration such that you go up the stairs to be faced with the toilet in the bathroom. This is a relatively large room overlooking the back garden. Except of course it doesn't, because the window has frosted glass.


The third "bedroom" is a very small single (just about) bedroom with the door on the left as you go towards the bathroom, and is presently used as an office.


I quite like having a large bathroom, but more and more it seems ridiculous to have the rooms this way round. If I changed them over, I could make the "new" bathroom even smaller and the "new" bedroom even bigger quite easily as the internal walls are partition walls.


I'm not intending to sell in the near future, but an estate agent has advised me that changing the rooms over would increase the value of the house as people want three double beds and aren't bothered about having a large bathroom. Obviously whether it would be worth it from a financial point of view would depend on the cost of doing it.


I could re-use some of the existing bathroom fittings, and the window at the side of the house isn't ideally placed but not impossibly so, so the sticking point would seem to be the soil pipe. I've googled it but there are so many variables it's hard to tell. I realise it would depend to some extent on the new position of the toilet.


I know I'd need to get somebody to come and look at it, but before I do, I just wondered what people's thoughts were and if there's anybody in a similar house in East Dulwich who has had it done?

I'm guessing (and this is only speaking as an absolute DIY bodger with many a plumbing disaster behind me) that if you didn't mind a boxed in soil pipe running across (as I can visualise it) the left hand wall of the new bedroom it wouldn't cost much at all? Hole in the partition wall and new external hole. Sounds awful but if it was at the back of a built in cupboard or the footing for a bookcase nobody would know...doubtless more informed people might know if that's allowable under building regs but...
I did something similar as part of a major house refurb to our house which was dilapidated when be bought it. The cost should be just the normal cost of fitting out a brand new bathroom plus a few grand to relocate the soil pipe. How complicated the new run needs to be depends on your existing plumbing though so the first person I'd speak to is a plumber who can let you know what solutions are feasible. I agree though that if its possible, its worth doing.

Thanks!


I can't really visualise what you are suggesting. Wherever the loo went in the new room, it would be on a diagonal to the existing one. Maybe I should draw a plan and attach it (not tonight!)

Thanks.


Yes, I will ask a plumber to have a look and then I'll have a clearer idea what would be involved and the likely cost.

LM's suggestion to talk to a plumber is far more helpful, I'm known for my Heath Robinson probably totally against regulations solutions! But I really don't think it should be too difficult - maybe 10% on top of the cost of a new bathroom? Good luck anyway, sounds like a good plan, never understood why people want large bathrooms, as long as there's room to bathe, brush one's teeth and (deleted for reasons of delicacy) then why does one need more? Far better to free up space elsewhere.

Sue if you want me to pop round for 10 mins I can probably answer your questions, I've relocated a few bathrooms previously so not rocket science to me - you could call it a free quote, without the quote. If you like that idea text me sometime.

Hey you're a star, will do!


Thanks!

Spend some money and do it properly via a qualified builder etc and stop being a boring tightwad on edf looking for cheapskate solutions ffs.



Well well, the lovely Grok having a go at me again.


As charming online as in real life.


KidKruger is a friend and neighbour of mine and I would value his advice if he has experience of moving bathrooms, so that I have some knowledge of what may be involved before getting builders and/or plumbers to quote.


He is hardly likely to give up his day job (not involving building or plumbing) to come and work on my house :))


Obviously I would get qualified tradespeople to move the soil pipe and the bathroom if I decide to go ahead.


FFS indeed.


ETA: Ah, I see the lovely Grok has edited his charming post.

Thanks Jeremy.


How much destruction was involved?!

Unfortunately it isnt.


The existing bathroom takes up the whole back wall of the back extension or whatever it's called, and the toilet is immediately in front of you as you come up the stairs.


It is on the side of the room adjoining my neighbour.


The new bathroom has an external wall at right angles to the back wall and on the other side of it, above the path down the side of my house.

What ed_pete said about the SVP, shouldn't require any digging/trenches.

I wouldn't make the new bathroom too small, when you eventually come to sell you want it to appeal to families.

Some other costs to allow for:


Building Control application fee and signing-off the works (maybe a planning issue too)


Making good the existing bathroom, holes, sub-floor, removing tiles = possible re-plaster/skim, changing opaque glass, extra electrics esp power sockets etc...

It would help to know where the existing SVP is located. If the toilet is on the party wall side it should either drain out towards the back wall to connect into an external SVP, or go straight down via an internal SVP.

Also, the position of manhole(s). If there's one in the side return then it would be easy to connect a new SVP into it from the new bathroom and ignore the existing SVP. If the manhole is adjacent to the end rear elevation then it's digger time...

Does that conform with any relevant regulations KK?

The Regs don't appear to make specific reference to going around 90 degree corners of buildings, probably because it's considered bad practice to begin with. When it's done underground they use what is called an 'easy bend', a very gradual 90 degree turning so that you don't get blockages. If a Building Control inspector did accept it he would probably insist that you have an access point for rodding out any blockages...

Also worth checking beforehand that the fall of the soil pipe running from the WC to the SVP doesn't clash with any door/window openings...

    • Does anyone know when the next SNT meeting is? I am fed up with my son being mugged on East Dulwich Grove! 
    • The issue must be everywhere at the moment. I was visiting a friend last week in Bermondsey, think we were walking  down Linton Rd & we dodged 7 dog poos. It was disgusting. 
    • Thanks for your message — I actually took the time to look into what CityHive does before posting my original comment, and I’d encourage anyone with questions to do the same. Yes, the Companies House filings are overdue — but from what I’ve gathered, this seems likely to be an accountant or admin issue, not some sign of ill intent. A lot of small, community-based organisations face challenges keeping up with formalities, especially when they’re focused on immediate needs like food distribution. Let’s not forget CityHive is a not-for-profit, volunteer-powered CIC — not a corporate machine. As for the directors, people stepping down or being replaced is often about capacity or commitment — which is completely normal in the voluntary and community sector. New directors are sometimes appointed when others can no longer give the time. It doesn’t automatically mean bad governance — it just means people’s circumstances change. CityHive’s actual work speaks volumes. They buy most of the food they distribute — fresh produce, essential groceries, and shelf-stable items — and then deliver it to food banks, soup kitchens, and community projects across London. The food doesn’t stay with CityHive — it goes out to local food hubs, and from there, directly to people who need it most. And while yes, there may be a few paid staff handling logistics or admin, there’s a huge volunteer effort behind the scenes that often goes unseen. Regular people giving their time to drive vans, sort donations, load pallets, pack food parcels — that’s what keeps things running. And when people don’t volunteer? Those same tasks still need to be done — which means they have to be paid for. Otherwise, the whole thing grinds to a halt. As the need grows, organisations like CityHive will inevitably need more support — both in people and funding. But the bigger issue here isn’t one small CIC trying to make ends meet. The real issue is the society we live in — and a government that isn’t playing its part in eradicating poverty. If it were, organisations like CityHive, The Felix Project, City Harvest, FareShare, and the Trussell Trust wouldn’t need to exist, let alone be thriving. They thrive because the need is growing. That’s not a reflection on them — it’s a reflection on a broken system that allows people to go hungry in one of the richest cities in the world. If you're in doubt about what they’re doing, go check their Instagram: @cityhivemedia. You’ll see the real organisations and people receiving food, sharing thanks, and showing how far the impact reaches. Even Southwark Foodbank has received food from CityHive — that alone should speak volumes. So again — how does any of this harm you personally? Why spend time trying to discredit a group trying to support those who are falling through the cracks? We need more people lifting others up — not adding weight to those already carrying the load.
    • Well, this is very disappointing. Malabar Feast  has changed its menu again. The delicious fish curry with sea bass no longer exists. There is now a fish dish with raw mango, which doesn't appeal. I had dal and spinach instead, which was bland (which I suppose I could/should have predicted). One of my visitors had a "vegetable Biriani" which contained hardly any vegetables. Along with it came two extremely tiny pieces of poppadom in a large paper bag.   This was embarrassing, as I had been singing Malabar's praises and recommending we ordered from there. The other mains and the parathas were OK, but I doubt we will be ordering from there again. My granddaughters wisely opted for Yard Sale pizzas, which were fine. Has anybody else had a similar recent poor (or indeed good!)  experience at Malabar Feast?
