Hi all,

First, please excuse my terminology in the following post...I am new
to the plumbing world.

Second, I want to add a bathroom to my unfinished (concrete floor)
basement. There are existing stubs for a toilet connection, and pipe
is already in place for a sink drain. My concern is for the toilet
connection.

1. If I simply attach a flange, wax seal, and toilet to the existing
stub (+ cold water supply line), will this be sufficient? I have
heard of 'venting', but have heard that each fixture requires a
separate vent to roof. It sounds expensive/unfeasable to run a
separate PVC vent to the roof for each fixture. Alternately, I have
heard that tying into the existing 4" stack maybe sufficient for
venting. I live in a 2-storey building. Is there any way to tell if
the roughed-in stub is vented correctly?

For what it's worth, there is a 4" stack in the corner of my basement.
The toilet stub is approximately 7.5' away from the stack. I also
see a cleanout and a drain.

2. For the layout I have in mind, ideal location for the toilet is in
the corner (right next to the 4" stack). This would mean *not* using
the existing toilet stub. Does anyone have any idea what would be
involved in this? Is it possible to dig up the concrete and connect
directly to the stack? Venting?

Wall-mount may be an alternative to breaking concrete, but I'm
interested in maximizing floor space (i.e. make the wall as thin as
possible).

I realize that any solution must comply with local plumbing codes
(fair enough...I am prepared to accept this). However, I am
interested in what options could potentially be explored before I
bring in a plumber for a 'free' estimate.

Best regards,
Dave
