    My missus wants one, I'm concerned there's not enough space or room for the plumbing etc ie the WC waste.

    It's a pitched roof, insulated with 2" PIR between rafters and 2" insulated PB below (when I get round to fixing).

    What are peoples thoughts on Saniflows or better makes etc?

    If you can’t get a pipe from the second floor to the drains then you shouldn’t be a plumber or a designer.

    Saniflow is noisy, needs replacing, ugly to clean out and to be avoided.

    Agree with Tony.
    +1 with the noise from Saniflow, especially if it's located above bedrooms.
    I can drop it through to the bedroom below and out that wall and box it in no problem. Can you get roof slates that allow the soil pipe to exit horizontally?
    Off topic, but as you have not fitted the 2nd layer of insulation yet, can I encourage you to make it thicker? Lay-up as described would not comply with part L1B.

    I have always been able to route the pipe through the eaves and soffit by notching into the wall plate a bit then nothing shows in the bedroom. I have see others go out through the gable and wiggle round onto the side of the house.
    I can go to 3" and I have a load spare. But I then need to add PB...

    What's the best way to fix this? Foaming the PB on would take up more space..

    And best fixings? 5" PB screws? Seem expensive
    I usually fix with 25 x 38 battens, to allow me to space exactly for 1800 x 900 plasterboards. If you do not need the service void you can fill it with 25mm Pu. I use standard screws.
    Tony I won't be able to go through the eaves as I have retrofit EWI so the new gutter system is right in the way.

    I think I'll just add in a roll top bath and wash basin
