    I'd like to buy an individual box spanner rather than a set of them to remove this backnut from a small bathroom basin. What size box spanner would do the job?

    Thanks

    Hard to judge but looking at other items to get a scale of things, I’d say 17mm. Won’t an ordinary 17mm spanner fit on it?

    Ah, I was looking at the wrong nuts! I think the one single brass nut is 11 or 12 mm. As S666 says, that set would be cheap enough to do what you want.
