Easy job. Requires: one wrench (or specific socket), two rags, one $2 putty knife, one new $5 wax "donut," preferably a small wet/dry vac or a bucket with sponge, one plastic grocery bag, and someone strong enough to lift toilet up and set aside and able to repeat process in reverse. Gazillion YouTube videos on this.

1. Turn off supply valve and disconnect water line to toilet. Valve is often a diamond-shaped or plastic pop-out looking thing;
2. Flush toilet. Remove remaining water (as much as reasonably possible) with vac or sponge from bowl and tank;
3. Remove nut caps (2) and unbolt toilet from floor. Lean toilet over partially;
4. Quickly stuff a rag half way into bottom toilet hole where it connects to floor this is to limit dripping;
5. Quickly stuff a rag half way into hole in floor to which toilet connects. This is to prevent you from enjoying the odor of sewer gas. And from dropping anything into the abyss;
6. Leave bolts in floor in place, the ones that are standing up about 2-3 inches;
7. Lift up and set toilet aside. Adjacent tubs work great for this, but don't crack porcelain;
8. Use putty knife to scrape away existing wax donut ring. Plastic bag helpful here;
9. Replace wax donut ring with new;
10. Remove both rags.
11. Set toilet on new ring. "Smoosh" around a little to settle it and achieve a good seal;
12. Re-attach nuts to standing bolts, and nut bolt caps;
13. Re-attach water supply line, check for leaks and turn on water supply valve;
14. Allow tank to refill. Flush a couple times, ensure water-tightness around toilet base and supply lines;
15. Throw out plastic bag with old wax donut ring. For those of you who like to sniff kids' hair, Do not eat this kind of donut.

Yeah- pretty much it, done yourself for under $10 and a half-hour.

Hope this helps.
