Installing an attach-to-floor toilet?
Hi everyone.
I'm having trouble figuring out how to install a toilet that is bolted directly to the floor (rather then bolted from the toilet flange).

It's a toilet that has vertical sides with no flanged section where you normally see the bolts. There are bolt holes on the inside though (accessible from the rear) which I believe line up with the regular toilet bolt holes.

But the instructions show the bolts go into the floor on the outside of the toilet, but I can't figure out how these actually attach to the toilet itself. The supplied hardware is bolts with plastic sleeves to drill directly into the floor.

Anyone deal with one of these toilets before? Any ideas?

Is this a 4-bolt toilet?

I don't think so. 2 holes in the toilet, 2 bolts included...
I think it may be a no-flange toilet? Seems to sit high when put on the flange, plus I see that the holes are not lined up with the drain, they sit behind the drain.

The toilet must be sealed to the flange with a wax ring to prevent waste water and sewer gas from leaking into the bathroom no matter how the toilet is mounted.
I'm not a pro plumber (just a long-time DIYer) and I am not familiar with a toilet like that, but if the bolt holes line up over the bolts sticking up from the flange, then that is how it goes on.
A flange should sit flush on top of the finished floor level (and be bolted to the floor) with only the thickness of the flange (1/4"+/-) above the finished floor level for a wax ring to seal properly. If the flange is too high, it will likely cause the toilet to rock and leak.
Good luck!

Thanks for the advice everyone.

I've think I've determined that it's just the instructions that are wrong, the bolts must go inside the toilet into the floor even though the instructions show them on the outside. So I'll just be leaving the flange unattached to the toilet, and making sure the toilet level with the floor as you suggest mike.

Make sure that the drain horn on the bottom of the toilet base is lined up with the flange opening and wax ring to seal it well.
