You can get waste pumps, but that is only if you HAVE to pump it uphill or something. Otherwise, plumbers will saw-cut through the concrete to lay the plumbing lines and then fill it back in with concrete when the work is done. In any case, they have to get down under the concrete, saw they will have to cut. Pump is probably not necessary unless you really do have to go uphill to your waste or leach fields.

If you want to install a typical 3 unit bathroom, you will probably need a sewer ejector. You drain all sewer to the sewer ejector and sewer ejector will pump it up to the closest 3" or 4" sewer line in your house. From there, it will drain as rest of the house.
It will cost you few bucks. Go to Zoeller.com site and see what they have to offer. But I would not install anything less than Zoeller 267 pump.

Milo is spot on! Zoeller is all I ever install (26 years now)... very few issues ever.

No indication this is a basement so pumping may not be an issue. Where does your current sewer leave the building?

Good point Bob...
Maxum... maybe you have drain pipes under slab that you can trench over to and connect into and gravity drain this bathroom..? Gravity drain always trumps pump!
Let us know...

As a non professional, I Just finished plumbing in a basement, at first I was considering a pump system just because of the thought of breaking up the concrete, however I HIGHLY recommend Gravity as Mark and Milo have said. I spent more time messing around trying to get the pump system height to drain. Granted my installation had the waste line right in the same room, it was not that difficult breaking up the concrete once its initaly broken( I used a 10lb sledge on 30yr old concrete). These guys are more than prepared and willing to help you, seriously consider it if possible :)
Just a basic knowledge will get you a long way and you will be much happier once your finished, took me about 2 days between breaking the concrete and pouring that fresh new concrete.
