Cuts on orbry tray - Tile Advice

[Oldshore]

Hi. I have just bought a orbry 30mm wetroom tray. 1200x900. It has a linear drain. I am looking for advice on the cuts as it has a 2degree fall but the sellers reckon I need to make a mitre from each corner to each corner of the drain? I have not decided on 300x300 or 400x400 so any advice would be good.
Thanks David

The sellers are correct. 'Envelope' cuts from corners of drain to corners of tray would not be affected by tile size as it is all about how you want them to be set out.
