@hurricane:

I wouldn't go overboard on the waterproofing. The tiles/grout are
normally sufficient because the water is running off too fast to allow
penetration. It's the joint with the shower tray that causes problems,
and using silicone instead of tile adhesive for the bottom row is one
solution.

That's an idea. I have some fancy plastic angled strip that fits unter the
bottom row of tiles that nicely seals the gap between the bath and the
tiles.

No. it doesn't. It traps water UNDER itself and draws it up by capillary
action,

snip

so when you seal your bath to the untiled wall with silicone and then
attempt to stick tiles to the silicone (which won;t stick to the
silicone of course) - what stops water creeping up behind your bottom
tile row by the same capillary action, soaking the pboard and ending
up with the same net result?
