I’m renovating a bathroom. The top of the toilet flange sits ½” below a newly finished floor. I was planning to use a flange extender that fits inside the existing closet flange, but someone told me that it was important not to narrow the hole. They suggested a flange riser (aka spacer).
Why? The flange extender narrows the existing flange diameter from 2 9/16” to 2 5/16” still larger than the 2 1/8” toilet trap diameter, the limiting dimension. Why would the extender be an issue for the ~7” from the toilet bowl horn to the 3” waste pipe?
Am I missing something?
