Because the bath is level, the water on the rim can flow in all directions,
including towards the floor side of the bath, where it runs round the ends
of the shower curtain and down the the bath panel onto the floor.

My 'next time' fix would be to slope the bath towards the tiled wall a
little so any water on the rim ran inwards, then drained into the bath.

Being reluctant to hack off the tiles and re-slope the bath now, I am
looking for a neat alternative to stop water on the rim of the bath running
off the edge onto the floor.

Cloths placed at strategic locations, as long as regularly squeezed, can do
this but they are unsightly and can be forgotten by those not initiated into
arcane showering rituals.

I was looking for something which could be used to produce a slight ridge
(couple of mm would do) along the exposed edge of the bath so that any water
would run into the bath instead of down the bath panel.

I have seen in one of the catalogues, a white plastic, self-adhesive corner
piece. It attaches to the top edge of the tub, and the side of the
wall/enclosure, and is specifically designed to solve the problem you
describe.
