I am having to re tile a portion of my shower cubicle which leaked. I
have replaced the lower section of damp plaster board with Aquaboard.
I was wonder whether it was worth using bath trim for the joint
between the bottom of the tiles and the shower tray, or just a bead of
silicon. If I use the trim what do I do at the inner corner, just cut
at 45 degress and lots of silicon?
Any thoughts appreciated

Thanks

Good move - showers always have problems with the odd bit of water seepage
through dodgey sealant, or a failing grout line - if not now, it will happen
eventually.

Can't comment on the trim but for silicone, I would:

a) Clean out and re-silicone the tray to the panel.

b) Tile (use water resistant adhesive rated for domestic showers) and a good
grout - powder mix is better than readymix IME. Leave a 4mm gap between
tiles and tray and rake out any grout thet gets in here to the full depth

c) Pump the tile-tray joint full. It matters little what sort of bevel you
use as long as there is a good plug of silicone in there. I like radius
beads, others like the 45 degree flat finish. Ultimately having a deep plug
of silicone will give strenght and long life to the joint even if the suface
finish deteriorates a bit.

It's when you apply a surface bead only (to a tight tile-tray joing) that
the problems happen (ie cheap fitting job where they forgot to leave a gap
between tile and tray or tile and bath). Should you end up in this position,
then I would be tempted to investigate the trim option - but a nice bead of
silicone looks neater IMHO.

Any thoughts appreciated

Use the trim that fits under the bottom tile (is actually tiled over)
and juts out over the tray. Fill the trim with decent quality silicone
- not the cheapy universal stuff. For the corner, mitre, as you say.
