Thanks for taking the time to reply....

1. don't have enough tiles to re-tile, sadly, and can't find anymore
beyond what I need to extend the tiled wall area around the new shower
enclosure. However, if I was to re-tile we wouldn't manage to lose the
fact that the corner is 90 degrees, so there would still be the gap.

2. When you say "quadrant trim" ... would a plastic quadrant trim,
siliconed on, be much better than, say, cementing a row of quad. tiles
and grouting them? For some reason a convex plastic trim not entered
my mind!
