I'd like to get a bath with an 'upstand' around the 2 or 3 wall edges,
but I don't know if these exist. Failing that, maybe it's better to
chase it into the wall, and then tile down to it? Or not?With a a bath it is indeed better to chase into the wall (this adds
rigidity to the bath as well), and then tile down to it. This tends to
"hide" the roll edge of the bath, and leave a flat surface to tile to -
hence eliminating one of the potential moisture traps at the edge.

If you tile down to the bath, leave a tiles thickness gap at the bottom
of the tile. Then when sealing, fill the bath with water first (to set
it at its lowest position), and then seal with a good quality silicone.
Don't let the water out until it is fully cured. This will ensure the
natural state of the silicone is slightly under compression, relaxing as
you fill the bath, rather than streatching (and hence more likely to
fail) as you fill it. The tile's width gap will also ensure the selant
gets a good solid key.

Would you roughen the surface of the bath with sandpaper to help the
silicone to key? I mean the part that will be hidden under the
sealant of course!
