Most toilets come with almost everything you will need to install it. Also, the "guts" as I call it in the tank is usually pretty much preassembled and installed for you. Working wise there is the base, the tank, the tank lid, the toilet seat, the wax ring and the two anchor bolts with wingnuts and the anchor bolts and screws to hold the tank onto the base. The only thing that you have to buy separately is the hose from the wall outlet to the toilet. I always change it out when I install a toilet.
The toilet above was from a bathroom renovation that I recently finished. You can find the details here
Now disconnect the water line leading to the toilet
You have a choice at this point, you can remove the tank or remove the entire toilet (tank still attached). I do it as one unit as I am always just disposing of the toilet anyway.
Loosen and remove the nuts at the base of the toilet (see picture above).
Rock the toilet towards you to loosen it and then pick it up and away.
I always replace those side bolts as new ones always come with the wax ring.
wax ring with anchor bolts if not included with the toilet
I turn the base of the toilet over and press on the wax ring just hard enough to make it stay. Then turn it right side up. Align the two bolts with the holes in the base and set the toilet down. You can actual feel when it is place. Push it down to set the wax ring.
When tightening the side bolts, just done't tighten one side down. Slightly tighten one side and then the other. Keep switching back and forth until the toilet is down all the way. Check to make sure it is not rocking.
Install the toilet seat and lid.
That's it. That's all there is to installing a toilet. Many toilets now include the wax ring, check the contents of your box before you buy. If not included be sure to buy the type that has the new anchor bolts for the bowl.
I hoped this helped.
