• I posted this floorplan not long ago and thought it'd be an idea to move the toilet from the back wall to under the stairs to open up the back room more - but I think I omitted the fact that it's a mid-terrace.

    Does that rule out the possibility of such a shift, as the soil pipe wouldn't have sufficient drop to cover 5m or so to the back wall/main soil pipe?

    The other option would be using a saniflo/macerator type system - anyone had any experience of them?

  • Hard to say without knowing the pipe work but I can't imagine it will be an issue as its not a massive difference.
    Macerators are hell on earth, I'd avoid.
    How much work are you getting done? Because that floor plan is screaming out to have the kitchen rearranged and big doors put in the back.

  • Doesn't rule it out, but does make it awkward. I managed to fit a toilet under my stairs in a very similar setup to yours , with the soil pipe boxed in at floor level -rather than underneath- until it gets behind what for us is the kitchen units.

    Everything I've heard about macerator toilets seems to agree, hard no.

  • You could use a saniflo, but be prepared to change it in 2 to 3 years as they just dont last for some reason.

  • Depends on how the soil pipe runs under your flooring.
    If you follow 1:40 drop, then its 25mm every metre, and 5m length (I imagine it would be less than this) would be 125mm.

    You should be ok I would think?
