toilet floor flange

ideally, the underside of the flange ring should rest on top of the floor, and the ring screws down into the floor. But it is fine to have the flange be slightly below the finished floor surface so long as you get a thick wax ring so that there will be a solid connection of wax between the underside of the toilet and the flange to prevent leaks. When you do buy a wax ring, make sure you spend the extra couple of bucks and get the thicker kind with the plastic horn/funnel that helps direct water down into the flange opening. Don't just get the cheap small wax only ring.

just curious and not to go off topic but is there anything wrong with using the rubber gasket ? I hear you mention wax but not the rubber one .Thanks

I've personally never used one, but I understand that those newer type rubber toilet seals work just fine. Only problem with them is that codes have not approved them yet in many places, so technically only wax ring types are approved.
