The previous owner had the bathroom carpeted which went around the toilet but not under it.
Install vinyl plank around or under toilet.
I removed the carpeting and installed some vinyl plank flooring lifeproof from home depot.
Whether you re laying ceramic vinyl wood or something else on your bathroom floor you ll deal with the toilet in the same way.
Install the vinyl plank flooring.
Installing under a toilet after you remove the toilet which is often a two person job you need to measure the position of the flange and cut a hole for it in the flooring using a jigsaw.
Then the toilet is reset so the base covers the cuts around the drain.
If you are installing vinyl planks in a bathroom you may need to temporarily remove the toilet or you can install around it.
If the subfloor is unlevel you can fix low spots with a self leveling product and sand or grind down high spots.
My question is about the mounting flange that was on the floor specifically regarding the height relative to the toilet.
Install full vinyl tiles on the bathroom floor stopping when the full tiles will not fit next to the toilet flange.
The toilet has to be removed and the flooring cut to go around the floor drain.
This will leave you with an uncovered area around the base of the toilet.
