The material doesn't really matter there - that's what the waterproofing membrane is for. My bathroom has a plywood subfloor with a 5 cm concrete slab cast on top, floor heating cables embedded inside it. Then there's a waterproofing membrane painted over that, followed by the tiles. There's even this rubber "funnel" over the floor drain that's fully embedded in the waterproofing layer, making it virtually impossible for water to go anywhere but down the drain.
I guess it depends on where you live. Here in the Netherlands those kind of membranes are rather new techniques, if I want something like that I wouldn't even know where to get it. I would probably need to buy it in Germany. As a consequence, nobody knows how to use the stuff properly. On the other hand, these days we have composite floor trays in any color which lay on the same height as the rest of the floor, and they're pretty nice.

That's anything but dull! Correctly installing a shower pan is difficult, even for professionals. Nice work!

What is this, a shower for ants?

Why shower tray instead of floor drain?

Good question. It's OSB subflooring with wooden beams underneath, also it's the upstairs bathroom. Floor drain isn't worth the effort.

Wet rooms are way harder/more expensive. (Here anyway)

Good call, looks like OSB subflooring? I would only do a floor drain on a concrete subfloor to avoid leakage. And probably not even then.
