Ironically, I appear to have a toilet flange that was properly installed on the finished tile floor (back in 1989??!!). My quandary is the top of the flange is 1/2" above the floor, exceeding the 3/8" to a 1/4" height standard. Measuring the toilet clearance (TOTO) this leaves about about 1/4" of wax gasket squish clearance (assuming a standard 1" thick gasket). Doesn't sound good enough. Should I worry about this, if the toilet sits level right on the floor?
It surprising to see that every replacement flange I've found is 1/2" high when it is properly installed on the finished floor.
1) I've searched in here and I've seen a discussion about the problem, but I didn't see a specific model recommendation that meets the requirement. Can you recommend a specific stainless steel model - less that 1/2" tall - that can get me to the correct height?
2) Should I use the horn in the gasket? Considering the lack of squish space, I am concerned about wax squeezing and obstructing the drain.
3) Do I need to put a gasket below the new lower flange? The additional height would kind of defeat the purpose.
3) Do I really need to reinstall a new flange incorrectly below the final surface to get this right? Kinda weird.
Thanks,
Beerski

1. 1/16 is plenty of space. You just don't want an interference fit.
2. No horn.
3a. Unclear. Are you saying that the bottom of the plastic ring is higher than the floor under it? Are there screws holding the ring down?
3b. Probably not. How about a photo. Note, it is usually better remove the rag in the hole for a closet flange photo, tho that probably does not matter for this purpose.

Hi Reach4,
Please is photos attached. The toilet flange sits on top of the tile..... the top being .5" from the tile floor surface.
I measured the inside of the toilet base and the bottom is flush with the integral raised ceramic ring and that measures .7" high.
Thanks for the quick response.

When using wax, try the toilet first without the wax. See if there I any wiggle or rocking that you can do. If there is, put shims in place, to stop the rocking, mark the positions, and lift the toilet. Drop the wax onto the closet flange. Make sure the shims are positioned, and then drop the toilet.

OK, I will give it a shot. Thanks!!!

It sounds as if the real experts have already provided you with a solution, but my two cents (from a DIYer, not an expert) is to use the Korky Wax Free Seal Kit. I've installed at least 4 toilets using it, and it is very forgiving with regard to flange height. Also, for the DIY installer, it allows you to move the toilet if you fail to drop it onto the flange bolts in the correct position. For a flange greater than 1/2 inch above the floor you simply remove one of the foam rings from the kit. I had to do that on one of the toilets in my new house, and it worked perfectly.
