Hi- we are trying to figure out where is best to place an upstairs toilet when moving the main bathroom downstairs due to needing a third bedroom for our child. I hoped to ask people if they thought it could work for us to add a small toilet and sink in the bedroom 1 space with a new soil pipe going out the side (we are end of terrace on this side). If this was possible, can anyone advise what kind of quotes this may cost to add a new soil pipe in? Many thanks

One thing you’ll need to work out is where the drains are outside. Look for manholes etc.

As said - do the drains pass by that side elevation?
 
Probably cheaper if you can run into the existing stack above ground.
 
We have a manhole cover out by the kitchen window (marked x in red in the picture). The existing soil pipe runs out the back of the current upstairs toilet. With the manhole placed here form your experience do you think this could be possible? And any idea on how big of a job this is/how costly? Many thanks

You are surely looking at £20/25,000 for that work which is effectively a new bathroom, a new ensuite, and associated internal building and drainage works. It wont add much value to the house (people tend to move bathrooms upstairs) so it might be worth buying a 3 bed, or splitting one of the existing bedrooms.
 
We brought the house knowing we would need to move the bathroom downstairs to make it a three bed (this was a property we could afford in the area we need to be in) and so had budgeted for the bathroom to be moved downstairs already. We are just trying to keep a toilet upstairs and hope to put this in the bedroom 1 as it is the largest room and would mean the other rooms are then still an ok size. We have things lined up for the bathroom moving downstairs into the conservatory area but just hoping to get an idea of how much extra it will cost / if it’s possible to add that small toilet into the upstairs area taking a small amount of space from bedroom 1…
 
It's a bit of a faff to say the least, and losing the upstairs bathroom won't be popular with future buyers.
What about knocking down the conservatory and making it into a proper extension? Which could then be used as a 3rd bedroom/whatever.
Depends on the age of the children really.
 
Thanks for the thoughts- we know it is upheaval :( the children are very young (toddler and baby) hence needing to be on the same floor. Just wondering if possible and if there was any idea of costing to add the toilet upstairs in that kind of space
 
As the kids are small you may be able to split the bottom bedroom similar to the below and keep the bathroom where it is

If I've got the scale roughly correct they shouldn't be too small rooms (single beds in blue for scale) Storage in red.

If they're so young, surely they can share?

I had to share for the first ten years, the road my dad grew up in had a family with 8 kids, in a two up two down terraced!
 
The house is needing to be renovated so we have been thinking to try to renovate it with the floorplan changes to future proof as far as possible to hopefully then just have to do this type of work once
 
Love them or hate them. I think a Saniflo might be your best option. unless the drain conveniently comes along beside your end wall. Even if it does you'll then have a shared pipe to join to which will add cost.

It will depend massively on the drains. Best case £3 - £5k
