    I'm doing my bathroom myself and will soon need to choose a new toilet.
    Close coupled best I think like the old one.

    Just wondering if modern loos have a standard soil pipe connection height. I noticed in B&Q that some were low and others were up higher.

    The pipe is still in situ from the previous loo and is 115mm from the floor to the lower edge.
    A new top floor will go down so will raise the loo height a little.
    Any help appreciated.

    you’ll be ok, especially as the floor is going up.

    It’s a problem when it’s the other way round

    If you have a look at a few WCs online you will usually see drawings which show the height to the midpoint of the outlet, then you can plan accordingly.
