I am replacing the toilet and tiling in my small basement bathroom.
Since I am doing tiling I will need to have the toilet off for several
days. After I take the toilet off, do I need to plug the toilet hole
in the floor so no sewage gases leak into my house? Please advise if
necessary to cover the hole and what should I use? And if I have to
cover the hole, how long can I keep it covered?

Stuff a rag into the top of the pipe. Keep it covered as long as you'd
like.
