Should I upgrade from Cast iron to pvc


Im at a point in a 1/2 bathroom remodeling project and need advice. This project was to overhaul a bathroom which the toilet was out use for 2 years. The faucet was used regularly. I replaced my subfloor, 3 shut off valves and painted. When I replaced the floor I did not run the subfloor under the cast iron flange to the pipe but instead directly around the outside of it because I cut a hole in the new wood to replace to rotted area around the toilet I have since replaced the wood which should exist under the flange but have not fastened anything down yet because im considering having the plumming replaced from toilet to sewer inlet with pvc and putting a newer style toilet flange. The cast iron flange is just fine after a steel brush cleaning and well intact but does have some area's where parts connect that seem questionable and somewhat corroded. should i consider just keeping as-is or go with new pvc

Depends on a lot of thing:

Cost vs. Budget (can you DIY or will you have to hire it done?)

Condition of cast iron

Access to old pipe (is the room below finished, etc)

Other "means" - can you get by without this bathroom for a while (guessing so, since you said....what?, 2 years? )

Can it be done in stages? Replace part of the cast iron now...more later....

how much would such a job cost? Cut cast iron pipe, about 1.5 feet of pvc str8 pipe, 45 degree elbow and then about another 1.5 ft of str8 pvc with a connection to the cast iron pipe. I can do the new toilet flange. The plumming I want to replace is easily accessible in a wreck room

Not a great idea to ask pricing when anyone ansewering could be from any country in the world and you have no idea what they even know.
Call localy and get pricing.

Best guess is piping materials would run about $60 assuming its 4", plus whatever you need for supporting everything. How are you connecting to the cast iron?

When a carpenter did our other bathroom he connected a rubber boot with 4 clamps to secure it to the cast iron portion and str8 pvc pipe. I have a picture of the setup but have a problem uploading it. I read that you can use a sawzall with a 8 inch 18 tpi blade to cut the cast iron but I know if I mess anything up it could be costly so I know not to get ahead of myself.

Don't believe everything you read. My Dewalt wouldn't do it in a time span measured in minutes not hours, although I've heard a Milwaukee will from a couple of people. You can rent a ratchet snapper or if you have room to get in there, a grinder with a cutoff wheel works great.

Do use 4 clamps on the rubber. If I have to use one of those on a horizontal, I also put a friction clamp on each piece, and run threaded rod through both sides, with fender washers and nuts on the ends past the clamps. When you tighten everything down real good, it all but eliminates the possibility of the pieces pulling apart over time.

Even if the cast iron is fine, considering the job would be simple and easy to get at, is it worth going with pvc at this stage of my remodel?

If you have the time, and its all wide open--if it were me, I would. Put down some new subfloor around the toilet with a zillion screws, a nice new closet collar and new pipe as far as you can reach--once you finish it all up, you won't have to touch it again as long as you are in the house, and everything will be rock solid. No leaks, no cracking tile, etc.. But if you just want to be done, let sleeping dogs lie and drive on. It'll probably be fine for a while.

check the fitting joints of your cast iron. If they show signs of leakage consider replacing. Examine the pipe closely for rust color on the outside. This indicates the pipe wall is getting thin and is about shot. Casual observation really doesn't tell you much as the pipe fails from inside out.
I'd really consider plastic if its something you feel you could do. Removing CI pipe does take special tools and is very heavy. You need to take precautions when removing it- the vent stack may come crashing down if not supported.
One nice thing about CI pipe is its quieter then plastic so you may hear water running down plastic pipe.

I've been on this project for a month already and before I complete the floor and put a toilet on I think I would rather get the CI replaced. Its at least 60 yrs old and the joints do have rust and corrosion around them and the inside of the pipe near the toilet flange certainly has corrosion inside
