Full Bathroom in Stubbed Basement

Please excuse my ignorance on this, and bad terminology which I'm sure I'll use - but here it goes....

I'm finishing my basement. In that we've built out a bathroom. This bathroom was stubbed when built (2000). What I have is a 4" drain for the toilet, a 2" drain for the sink(i believe), and then a drain for the shower with dirt around it.

My questions are:

Does the sink drain simply connect the 2" drain through the wall?

Do I need to worry about venting for any of the drains(or should it have been designed with a wet vent)?

My Dad and Brother-in-Law have been helping me with most of the work but they live a few hours away and haven't been able to come up lately. I have the supply lines tapped and simply have to tee them off and run to the shower, sink and toilet.

Thanks for the help - love this place.

Most if not all areas across the United States requires vents on your fixtures. Check with local codes to clarify this. You can use a 2" tee with a reducing bushing and turn out 1.5" for the drain; the top of the tee can be reduced to 1.5" as well serving the vent.

There should be a vent for the shower as well.
