Be sure to put a "P" trap in the condensate drain line, what ever you do
with the water.

Why does the condensate need a trap if there is already
a trap in the shower drain?

I don't have a trap on mine.
It's all 3/4" PVC running to the sump.
All gravity.
If you have a condensate pump and tank, your idea of going to the
closet drain is fine. *Check your local codes.
You are talking about running the condensate line from near the
basement floor to ceiling height, right?
If the condensate pump check valve is near the pump, the line going to
the shower drain will always be full.
So you can use a saddle instead of a Y above the trap.
Saves space and work.

In your setup you dont have to worry about any obnoxious gases backing
up into it. Not only is sewer gas stinky it is corrosive. Dont trust
the check valve on the condensate pump. We use them here at work on
our humidifiers and both failed within a year. I think we put in a
Watts check valve and it has had no problem since. Use a trap anyway
it keeps things out of the pump you dont want in it as condensate is
often contaminated with mold and algae.. Use some couplings so you can
take it apart if it ever becomes clogged.. The other line of thought
is glue it all up and put the couplings in when and if you ever need
them.
