Replacing an existing toilet is a straightforward task because the supply and waste pipes are already in position. If you want to install a toilet in a new position, it requires more complex rerouting that is best done by a professional plumber.

Before you begin gather the right equipment. You will need newspapers or old towels to set the toilet on after you remove it. A mistakenly dropped toilet could crack a ceramic tile floor. Also, make sure the new toilet fits inside the space occupied by the old toilet. Some newer models are available in longer and larger sizes than traditional designs and may not fit within the room.

Drain the water

Shut off the water supply to the toilet. After the water supply is disconnected, flush the toilet several times. Flushing repeatedly will remove the water from inside the tank and most of the water from the bowl. If there is any water left in the bowl, use a container to scoop it all out. If you leave any water in the old toilet it may leak out when you carry it through your home to dispose of it.

Disconnect the toilet

Unscrew the nuts that attach the toilet to the water supply line. Then, remove the caps that cover the bolts on the base of the toilet. Unscrew the nuts located under the caps. Lay out your towels or newspapers, then lift the toilet from its position, being careful to hold the bowl, not the seat. Place the toilet on the towels or newspapers.

Loosen the Seal

Use a utility knife to score the between the bowl and the floor and then free the toilet by rocking it from side to side. Lift the toilet away onto some old towels or newspaper. Remove the wax gasket using a putty knife or similar tool. Block the drainpipe with a rag to prevent sewer gas escaping.

Apply Caulk and Set

Apply a bead of caulk to the base of the toilet. Remove the rag from the drainpipe. Lower the bowl into place on top of the flange and press down.

Fasten Bowl to Floor

Gently tighten the washers and nuts onto the bolts. Tightening too hard can crack the porcelain.
