Hey,
I am a handy home owner who would like to build a bathroom in my basement. I have only done minor plumbing at home. Here are some pictures of what the basement floor looks like. I was told by my home inspector that this is a rough-in but I don't know which pipes are for what. Do you know?

Here are some pics, in the rectangular shaped hole there is a 4" capped pipe, in one of the round holes there is another 4" capped drain then there is the long pipe sticking up but in the other 2 holes there is nothing inside.

That's kind of unusual. The orange capped pipe is probably a toilet.
The can located above it- tucked to the corner might be a shower.
The rest of it- I couldn't guess. Are the walls located per the drawings? The reason I ask is when you see a box out in the slab- you assume a tub or shower goes there but yours is in front of a door.
Have you dug down in the cans yet?

Orange is water closet
Tub is the one with wood around it
First pic is the floor drain
Other for the lav.

Room seems kinda small for a full bathroom. Maybe a pic showing the entire space could help give us better perspective.
