    Hi.

    Just wondering what the length of overhang should be for a nice finish.

    I've left 7 inches ( 17.5cm)

    Is that too much or about right?

    Aiming for something like in pic.

    Cheers

    Any length you like within reason.

    This is one of those times when quantity is important.

    Totally agree. From your experience would you say 17.5cm is ok?

    Enough to fit a grill for the extractor fan in the toilet.
    That way you won't need to drill the walls and will have a neat finish.
