I'm adding a bathroom to my basement and want to make sure I don't screw-up.
Stool: The rough-in is 10" (?!!) and the drain is 3" and doesn't yet have a flange. There is also 1/2" ring of stirofoam around the pipe, maybe just filler to hold back the concrete. There are no supply lines. There is a 2 1/2" ABS pipe capped nearby, the vent, I'm guessing. What should I consider with the flange and the anchors? Do the anchors need to be fastened to the concrete? Being less than 12" off the main, does it require venting?
Sink: An auxilary stack has a Y for the sink drain. Again, no supply lines. I'm not sure what to ask about this part of the project.
Shower: There is a 10" opening in the concrete where I assume there is an attachment to the main stack. I need to dig in there and see. There is a capped 2 1/2" ABS pipe nearby, again, I'm guessing for venting. There are no supply lines. How do I determine where the drain should be placed? Are there any considerations other than adding the trap?
I'll fess up; I'm not a plumber. But I'm confident that I can handle this, given a fair amount of time and help.

Is the measurement from the toilet 10" from the center, or back edge?

10" from the wall to the center of the rough-in.

Follow-up: I finished the toilet and sink about ten days ago. I used a toilet with 1.5gpf and a (somewhat rare) 10" rough-in but was skeptical about its ability to flush clog-free. My family routinely clogs the higher flush units upstairs. After ten days of use, the basement unit has remained clog-free without a single clog-scare (that's where the water swirls and pauses before exiting the bowl).
The flange installed easily after I removed the stirofoam from around the outside, although some fool put duct tape around the outside also. I removed the adhesive residue with a solvent. I cut into the main stack and vented the toilet and the shower drain while I was at it. The supply lines sweated quite well, and, I have to admit, it was kinda fun to be sweating copper again. I used the old bread plug method to stop the residual trickle of water from botching the soldering effort. One thing I forgot was to remove the aerator from the faucet before filling the lines again. The aerator on one of the newest faucets upstairs has a screen so fine that the bread stuck almost invisibly into about half of the openings causing a strange stream that didn't clear out by itself.
This project took me several evenings to complete, and most of the time was spent getting the correct parts (starting with the correct toilet). Someday, maybe soon, I'll start on the shower portion of this project.
