New Bathroom

I am thinking about adding a bath on the second floor. I am not new to this type of work. One thing Im not sure of is tapping into the drain for the toilet. Can someone tell me the best way to do this.

Is there already a bathroom on that floor? If so, how far is the main drain from where you want to install the new bathroom? Is it cast iron or PVC?

There is nothing there.
The toilet will be about 24" from the main pipe.
It is cast iron.
The main is vertical that I want to tap into.

24" isn't bad at all. I would use a PVC T or Y connected to the cast iron with a rubber coupling. I'm sure you have to vent that pipe too. If you can't cut the cast iron with a carbide blade, you'll have to rent a cracker to do it.

Thank you

The PVC will hold the weight of the pipe?
Does the pipe continuing out the roof need to be permanently supported?

There shouldn't be that much weight transferred to the PVC from the cast iron. The cast iron pipe is already secured to the studs &/or joists. I would secure all pipes, including the vent.
