How do you get water out of a toilet before removing it?
I will usually pick the toilet straight up and set it in the tub if there is one. Put a towel in first to protect the tub finish and then tip it front to back several times to cause the water to come out. You can set the toilet into a pan big enough to hold the bottom and then carry it outside or rock in in the pan. There is only about a gallon at most in the base of the toilet after you have flushed it.
