Basement bathroom plumbing question/concern

[aaron79]

Hi, Im a DIY Plumber

Im working on moving my plumbing in my basement to the other side of the soon-to-be bathroom. I've busted up the concrete and replumbed all the fixtures and was about to close it up and starting having anxiety that I did it wrong. Hoping someone can help me know whether my approach will work or not. I've attached photos and a diagram that I hope will help. My goal was to limit any additional concrete tear out since I returned the tool.

My concern is that everything is on the main line and not branched off from it (e.g. the shower run through the toilet. see pictures.

I really appreciate any help in this matter.

Your only saving grace is the shower is running through the toilet waste.
I would never run a toilet waste into an junction like you have installed, due to blockages.
I would do a 45 junction with a 45 bend on top,

You may want to run the shower while taking a 'number 2'

That being said. Blockages are rare and you always have the shower upstream to get an extra amount of water through the drain
