Cast Iron Flange and Installing New Toilet
I am trying to install a new toilet in a second-floor bathroom, built 1950's. The bathroom floor is ceramic tile. The cast-iron flange is connected to a 4" soil pipe. The flange is rusty and deteriorated, but seems like it will still hold new closet bolts.
The problem I'm facing is that the flange doesn't rest on the floor; there's a 1/4" gap (partially filled with some ancient, dried putty that I can scrape out) between the flange and the ceramic tile. Top of the flange is 3/4" above the floor. The toilet base has only 1/2" of depth. So when I put the new toilet on the flange, the toilet isn't resting on the ceramic tile, and it shifts and wobbles.
Should I use a bunch of shims? Try to grind down the flange with a grinder? Find another toilet -- do they vary in depth? I'm new at this.
Thanks for any help!

sometimes , when all you got to work with is what is laid before you
you simply have to improvise to get yourself out of a mess.
Very few old floors are completely level, ect... so you work with what you got. Some floors I have seen were so rotted out their was very little support left to work with, and of course the customer didnt want to spend the extra money to do it right. You do what you gotta do.
As far as the toilet having to sit completely on the floor, yes that is best, but this is next to best and we both have seen it work fine all the time.....
Unless someone is going to make love on the damn thing, their is never going to be enough bounceing to ever compromise the seal or crack the china.
And if the dap is used liberally, it is basically all one with the floor level or not..
Once, in a dirty old rental dump long ago , I got myself into big trouble. Their was literally no crawl space, and only a 4 inch lead pipe stareing up at me through the mud.
No crawl space and no decent flange either. No way to do anything right.
I had to wood screw down a PVC flange onto the old lead lip into the wood ,
Then around the bottom of the toilet bowl, I spread a 1/2 inch bead of clear silicone very liberally. Then I set the toilet onto the flange, and I pressed the silicone under the lip of the bowl with my finger, basically glueing the toilet bowl down onto the floor.
I wiped off the excess silicone and it looked very , very good.
I screwed down the bolts till they were snug. Then I got the hell out of there. That was 20 years ago and I never heard any complaints.
That toilet was never ever comming up again., and I pity the next poor bastard who has to mess with it.
