Well I s'pose the first thing is to try and avoid having any gap
betwixt bath and tiles but presumably in your case that's not
possible. When I had my previous bath the two walls ( one long ,one
short) were not at right angles to each other so it meant there was
quite a large gap so what I did was secure the bath,fill the gap with
loads of silicone ( I happened to have several tubes handy) and then
got a plastic trim ( heavy duty stuff from Homebase..I think Trend
/Trent ? made it ..possibly it was intended for above a row of tiles
as a substitute for border tiles ....it was about 3-4 cm deep and I
siliconed it across between bath and wall (using a mitred join at the
meetings of the walls) so it sat at about 45 degrees from vertical and
this allowed the water to run off in to the bath .

Fill the bath with water before sealing it.

You can buy an 'L' shaped plastic extrusion with flexible edges in B&Q
http://www.homelux.co.uk/index.php?l=product_detail&p=78 which will cover
fairly large gaps. I use Evode Nail & Seal to stick it down. They do
corner & end caps as well.

Always been told that myself and always done it - but isn't there a danger
that the sealant bond will be damaged when the bath's emptied and raises
back up to its 'empty height' (and the sealant is compressed)?
In a lot of setups the bath forms a sliding joint against a wall, rather
than the wall protruding over the bath a little, so (unavoidable)
compression or tension seems equally bad.
I've wondered before if it's better to half-fill the bath so that it's
halfway between its maximum and minimum height...

What I have always done to date is first of all level the wall,
typically with an MDF sheet plus battens if the wall is seriously bowed,
then butt the bath hard up to that, then silicone to it and then TILE
OVER the seal.
This has proven to be 100% effective

the bloody thing flexing in the first place, or buy a better bath..

That's exactly what I do... seems do work fine.
