So I decided to try and tackle this installation job only to find that it is non standard. My old toilet has a regular floor flange, but the parma does not appear to work with that. There are 2 holes in the body for "lag bolts" which appear to go into the floor. The toilet came with a new wax ring as well. So if I were to guess, I would think that this toilet does not attach to the floor flange at all and just sits on the wax ring and the floor and is held into place with 2 lag bolts which must be drilled. Close? I am hoping someone else on this forum has installed this toilet and can provide me some assistance. The instructions are not that great as they provide not detail.
