Get in there then....chop chop!

 

@Nickfromwales, I took the plunge five days ago, nervously monitoring the state of the ceiling below the shower afterwards.  So far, there's no sign of water, but if there's a leak from the shower and it's only a slight leak then it may take several weeks to penetrate the plasterboard ceiling of the room below.  But so far so good, and I'm inclined to think the problem was the leaking tank in the cupboard directly beside the shower.  I've checked the point of the leak on the tank and it's still dry.  So I'm hoping that in a couple of weeks' time it will be safe to paint some stain-block over the brown stains on the ceiling of the room below, and then paint over that.

 Thanks for nudging me into summoning up the courage to test the shower!  😅
