Shower in the basement, do I dare?

Seems like every task I take on, gets more complicated.

This time, I'm adding a bedroom to a large portion of our finished basement.

We already have a half bath (toilet/sink) there. I'm assuming it was done correctly as every model of this house in our plan has the same half bath.

The question is however, how big of a deal would it be to add a shower stall? The stacks are about 10' away against the wall, the half bath is toward the middle of the house.

Is there a requirement to have a pump installed because the trap would be lower than the drain? I wouldnt think so as there is a drain very close by that I guess is there in case the water heater goes, I would assume that is trapped otherwise I would smell gas.

Could I simply break up the concrete up to the toilet and tie in there? My senses tell me NO and , that venting may be an issue. I still dont realize all this venting talk. None of our sinks/toilets is connected to vents that I can see. IE: I can see under teh unfinished part of the basement drain pipe coming from the kitchen sink, which runs to the main drain stack.

I really dont know where to start, and hate paying people to do what I could do but I think Im way over my head on this one.

 

In most places in the U.S., an install like this requires a permit and inspection. If you do not understand venting, you would not be likely to do this correctly, and it would probably in your best interest to get a licensed plumbing company on site.
