How do I tile on top? Is there a pattern to follow?
The shower tray is 4-way slope, there's a line from the corner of the board to the corner of the drain. Your tiles have to be cut according to that.
You can see the technical diagram on the appropriate tab, it shows the slope. In general you should something which looks like an envelope once the installation is over.
I am happy to help if you have any further questions.
