Replace lead with pvc

[Brando79]

Goodafternon
I am going to be redoing my bathroom and currently the toilet is on shims I’m assuming because the flange is too tall. I want to replace the flange when I do flooring but I found it is lead underneath. I was wanting to cut it at the brass and use a no hub coupling to convert to the pvc. The OD of the brass is 4.25 and I read most recommend a 4x3 closet bend for toilets. Is a 4x4 closet bend a thing and recommended or should I reduce to 3” and use the 4x3 closet bend. Open to all constructive critism. Was hoping to not bother the cast iron hub and use a donut unless that’s the absolute best plan. Don’t wanna open a bigger can of worms. But all help is appreciated

Why not just cut off the floor flange and then cut the lead waste line to the proper height and solder in a new floor flange?

Are you presuming that the new flooring will not be higher than the old flooring?

How high off of the current floor is the bottom of the toilet?

I am thinking that might just be a 4 inch medium bend, but I am not sure.

You might be able to use a 4-inch Push-Tite flange into the lead pipe.
It is too bad the Sioux Chief 887-GPM Closet Flange has been discontinued. The 886-GP is available.
