: I am looking into addig a basement bathroom to my house. it currently has a solid cement loor and a septic system ( I should also mention that most of the pipe for the septic is cast iron, except for 1 piece of what looks like brass coming up from my current sump pit) I guess what I am asking is what is the best way to install the plumbing for a toliet, sink, and shower??
The first thing to do would be to contact a licensed plumber in your area to see if the bathroom could be installed where you want it. The are many issues concerning plan approval, permits, drain piping elevation, venting, etc.
Good Luck. e-plumber
