I have just installed a rectangular Wedi shower tray (www.wedi.co.uk for 
those not in the know) and am about ready to tile it with white ceramic 
mosaic tiles.
I`ve done one before with large tiles and you basically have to cut the 
tiles so there is a line from all four corners to the small square drain in 
the middle. This is so the tiles don`t 'bridge' the valley from all four 
corners to the drain and potentially break if stood on.
The mosaic tiles are 4.5cm by 4.5cm and appear to be small enough not to 
need a line cutting from each corner to the drain in the middle. If so this 
will make the job a hell of a lot easier.
Has anyone else had experience with tiling a shower tray with mosaic tiles 
and what did you do?

Also, the tile adhesive I`m using (Dunlop waterproof ready mixed) doesn`t 
recommend using it for the floor tiles. Why is this?, should I be using a 
cement based adhesive for the shower floor? The Wedi tray itself has a 
cement based surface so I presume the bond would be better?

Just built a wetroom myself and the mosaic tiles were simply laid ontop
of my aquadec using normal tiling practices. I actually got a mate of
mine to do the tiling for me this time due to time constraints but he
suggested I use mosaics for the very reason you mention above. Awesome
job the tiles simply follow the built in falls of the tray.
