I am replacing a basement toilet that had developed cracks on both sides of the base. The toilet was not level, but it did not leak. The basement floor is concrete (1960s) and the waste line is 4-inch cast iron.
There is no flange, which I’ve learned is not rare for toilets installed on concrete floors. However, it looks like there are threaded sleeves installed in the concrete, and the bolts that secure the toilet go into the sleeves. At first, I thought there might be tile on top of an old flange, but you can see the sleeves rise above the floor a little, so I don’t think there is a flange. The sleeves are secure and do not wobble. Given that the previous toilet (from 1981) did not leak and the bolt sleeves are solid, is there any need to install a flange or do any other repair?
The toilet I removed was installed with a standard wax ring and an extended plastic horn (see image). I was planning to use a wax free gasket (e.g., Fluidmaster 7530P8 or Korky 6000BP) for the new toilet (Toto Entrada b/c small space), because I’m not confident I’ll be able to shim the toilet level on the first try. Please let me know if you think wax free will work in this situation with no flange and a recessed (1/2-inch or so) waste pipe.
Thanks for your help.
