I'm about to install new vinyl flooring but noticed that the toilet flange is rusted a bit, slightly angled, and higher than the subfloor and the new floor. https://imgur.com/RjfDeRs

  • Should I cut out and replace just the metal ring? before I install the toilet? I might still end up with a gap though.

  • Instead of having the vinyl plank underneath the ring, I tried attaching a luan plyboard ring that I could place underneath/ like a wooden shim to keep it stable and then I could screw it in with some wood/deck screws? I'm doing this so that the vinyl plank is not affected... I will seal the gap between the vinyl and the plywood+ ring with siliconized caulk. Would that work? https://imgur.com/MH1gdRA

  • I've had no issues with the toilet rocking or anything like that.. so wondering if I should just let it be. Install a new Wax ring / Danco rubber+ wax ring and call it a day?

  • Hey @JohnPolo The first part worked but not sure about the Sani seal. First of all its not available and then I've found mixed reviews for that product so a bit hesitant to wait for it to be delivered. I was hoping to get more responses on the options available here - wax ring / Better than wax - fluid master seal. Is there a better way to do this?

  • I don't know much about plumbing in general or toilets specifically. There are several posts on this site. I recently had issues with replacing a toilet and there is lots of information on my post: diy.stackexchange.com/questions/298034/… and I see in the related questions for your question this: diy.stackexchange.com/questions/57432/…? Maybe you can find more information that can help you? I tried several different rings/seals and none worked well for my case.

If it were me, I'd do as you planned, however I would use this soft rubber seal.

I have used them on dozens of toilets and never had an issue. It makes having a flange that is high or low, or not level a non-issue. They are a little pricey, but well worth it. Some of the bigbox stores carry them too. Far better performing than other foam/ rubber rings. If you need to remove the toilet for any reason, the seal can be reused.

  • Do you mean go ahead with the plywood shim to level the existing flange and screw it into the subfloor right? Also, I checked, and this rubber seal you mentioned is available near me... I have standard or jumbo wax rings/Danco rubber+ wax / Fluidmaster better than wax/korky wax ring. these are the available

  • #1 yes use the plywood shim and screw the flange down, but not too tight to deform the ring. #2 NONE of the seals you mentioned work as well or have the soft forming properties of the SaniSeal. I don't recommend or use any of the ones you mentioned.

    Got it, thanks! The sani seal would have to be shipped out and it'd take a week, cant wait that long.. so I'd probably have to go with the standard wax ring I guess

  • It is normal/proper to have the flange/ring 1/4" proud of the final finished floor. It is not normal/proper to have the flange unsecured and supported only by the pipe. Commented Apr 12 at 3:42
