Hello! I’m working on the bathroom and have finished with the drains and pipes.
Now I’m going to pour concrete into the "pit" where the pipes are.
Any tips on concrete? I was thinking about some type of cellular concrete.
It’s about 160x30x20 LxWxD. I'm going to lay water loops over it and then level it.

I would probably have used "regular" concrete, like coarse concrete from byggmax or similar, I think. EPS concrete probably doesn't provide much insulation value on that small area.
Reflecting a bit on your routing of the sewage pipes, it looks a bit hard to clean..? Or is it just me who thinks so?

Sometimes two 45s can be easier from a cleaning perspective. But as mentioned, 90 bends work too.
By now, you've probably already finished the bathroom, but it might be good to know that it's not allowed to splice tap water in the wall without having an inspection hatch. But maybe you have one?
They are no better than anything else, so they are not allowed either. It's okay to build in heating pipe joints, but not water supply joints. They must be inspectable from the outside, otherwise you might get serious water damage.
