    I am considering fitting a toilet in our utility room and need some advice/assistance.

    The house is a 1930's ex council house and the previous occupants have transformed what would have been the outbuilding into a decent utility room. There is water into it as the washing machine is housed in there. It is a good size and will accommodate a toilet and sink, partitioned off from the rest of the room.

    My initial thoughts were that I would have to fit a macerator as the soil stack for the house bathroom is on the opposite side of the house and it is not feasible to tap into that.

    Having never fitted one before I am not sure how the waste from the macerator should be routed.

    However, having looked further at the outside there is, what I believe to be, a sewer drain right next to the outside wall of the utility room, in our back garden. Having lifted the cover it appears that this is a shared drainage as there are pipes coming from the neighbours on one side and heading off in the direction of the neighbours on t'other side.

    So, am I best fitting a short soil stack to the rear of the utility room and running this into the existing sewer drain, rather than using a macerator?

    If so, what, if any, permission do I need? The info. I can find online is, to me, a bit confusing and I cannot determine if this is a private sewer because it's on my land, or if it's public because it's shared.

    If a macerator is the way to go, then where do I run the waste to?, the same sewerage drain?

    Any info/assistance gratefully received.

    your best option is to contact building control, as they will need to come and sign any works off

    i would if you can try and get it into main drainage

    Whilst macerators are sometimes the only reasonable solution to a WC locating problem, if there is a way to do it "properly" and it can be done within your budget, I would go with a standard toilet every time.

    Macerators have their place for sure but they should never be first choice.
