Had occasion to remove and replace a toilet this week. My first time but it didn't look too difficult on You Tube. Big guy, lightweight 2 piece toilet, just line it up and set. But mine is a heavy 1 piece fixture in a tight spot, and I'm not a big guy.
Trial Setting
Could not get the bolts to stay standing while I tried to get it into position.
Placed it with the bolts removed. Put 3 pieces of blue tape on the floor; left right and front, to show where it had to land.
Made some wood blocks to set it on then rocked it down one side at a time. Success!
Now with the wax ring in place
The wax knocked the bolts out of position.
Stuck straws down thru the holes in the fixture and over the bolts to keep them lined up.
Rocked it down from the 2" blocks to the 1" blocks on one side at a time then to the floor. Success!
Notes
The blue tape worked great, I use it for everything.
Did not have any straws in the house so made them with paper and tape.
8 blocks worked great, 6 would be ok.
If you can find a Sumo Wrestler, he will have the skills to do all this without the props.
Or you could hire a plumber.
