I have an unfinished basement that has rough-ins for plumbing. I would like to finish it some day, and I'm trying to envision what a bathroom would look like.
What purpose are the pipes for? Toilet? Tub/Shower? Sink? Wetbar?

The small one in the top left coming out of the floor is likely for a shower or tub. The larger diameter pipe coming out of the floor is almost certainly for a toilet. The smaller pipe to the right of the toilet that continues up is for the lavatory (i.e. sink).
You can tell these things because:
- The toilet requires a 3" rough-in.
- Showers and tubs require rough-ins within the floor and the rough-in must contain a P-trap. So you can confirm that pipe in the top left is for a shower or tub by taking off the cap and pouring some water in it. If it "fills up" some before draining, you'll know it has a P-trap and is indeed for a shower or tub.
- The sanitary tee in the pipe that continues up is placed approximately correctly for a vanity sink.

Works for me the stubs look a bit tall but better tall than two short.– Ed BealCommented Aug 3, 2018 at 23:34

I don't think it merits a dedicated question -- but is there a standard way to pop that cap off, to test if there's a trap? I don't want to cut the PVC yet :)– jglouieCommented Aug 6, 2018 at 16:13
