Hi /diy/. This is my first time posting here. I have an old toilet that I want to replace in my bathroom. I think that this project might be harder than it sounds. I don't want to tell my landlord, because I have a feeling he would make it a bigger deal than I think it has to be. My bathroom already has problems with the tile, I think there is a bit of mold under it. But anyway, this is an old toilet that has really nasty stains on the bottom that don't come out, no matter how hard you'd scrub. Plus, the seat, I found out, is wooden, and I just want a new toilet.

I've looked online at some videos of replacing toilets. It looks moderately simple, but I think it might turn out to be harder than it seems. Does anyone have any experience with this? I'm mostly worried about the wax seal (I have no idea what it will be like), I'm worried about the tile (I don't know how mad the mold is, or if there will be problems with placing the toilet based on the height of the tile), and I'm worried that it might just be an old design that will be difficult to remove.

Here is a link to some videos I've already watched:

After writing all of this out, I think I might just tell my landlord. Thanks for your help /diy/.
