Question about leveling toilet.....

I'm setting a bowl in an old house.

The floor slopes towards the front of the bowl by about 7/16" over the front-to-back of the bowl footprint. But the top of the bowl--where the seat goes--is close to level. (It's level side to side)

Wondering if the top is supposed to slope back and I need to shim the bowl in front. It would be a little bit of a job to do that neatly.

Can anybody advise if this situation will have any effect on the functioning of the toilet?

Thanks.

The toilet would likely still function just fine, but I would be concerned about feeling like I was at risk of sliding off at the front. Personally, I would find some way to level that bowl fron to back, and that *might* even include some grinding on the bottom of the bowl.

I would still set the bowl flat on the floor.
You wind up with more water in the bowl, but that's not so bad.
