I removed the toilet and installed vinyl flooring in the bathroom. The flange is flush with the new flooring. I was advised by Home Depot to get a riser and the Fluidmaster (35B) Wax Extender Kit.

Do you think that the Wax Extender Kit will be enough for a good seal without the riser?

Thanks,

Flush with the floor is fine, do not need a spacer. Some HD guys know what they are talking about, your guy is not one of them

Thank you! This has made my life simpler.
