I was planning on putting in a flow switch and timer. A little bit of training would be needed but-

Go into bathroom / toilet etc, turn on tap briefly, flow switch detects, circulation pump starts on timer, do something for a minute or so (e.g. go to toilet) and then use tap.

You could still use another timer to run the pump at times that the bathroom is normally used.
