If an old toilet is giving you frequent trouble, replacing it may be the best option. A new toilet can solve many problems and should provide years of trouble-free service. It's also a good opportunity to install a model that saves water. Removing the old toilet is the first step in replacing it with a new one. Both processes are moderately easy projects to do on your own.
Before You Begin
Shut off the water supply to the toilet by turning off the shutoff valve located on the supply pipe below the toilet tank. The valve may also be mounted on the wall behind the toilet.
If your valve is as old as your toilet, it might be a good idea to replace it as well. Replacing the valve is easy to do while removing the toilet. If you plan to change the valve, you will have to shut off the water to the entire house at the main shutoff valve.
Watch Now: How to Drain & Remove a Toilet
Equipment / Tools
- Tongue-and-groove pliers
- Flathead screwdriver
- Utility knife
- Putty knife
- Latex or rubber gloves
Empty the Toilet
Remove all of the water from the toilet bowl and tank. After you've turned off the water, flush the toilet to get the water out of the tank. Hold down the handle until the water stops draining. Remove any remaining water out of the tank and bowl, using a large sponge and bucket. Put on rubber gloves and use the sponge to soak up the water, then wring it out in the bucket.
Prepare the Toilet for Pulling
Disconnect the water supply tube from the toilet tank, using tongue-and-groove pliers to unscrew the tube's mounting nut from the tailpiece on the water inlet valve, located on the bottom left side of the tank. Remove the plastic bolt covers at the base of the toilet bowl, prying them up with a flathead screwdriver. Use pliers to remove the nuts and washers from the toilet floor bolts (called closet bolts).
If desired, disconnect the tank from the bowl by removing the nuts under the tank that fasten the tank to the bowl. You may need to use a screwdriver to hold the slotted heads of the bolts inside the tank in order to turn the nuts. Pull the tank up and off of the bowl to remove it.
Cut the Caulk Along the Floor
Cut through the layer of caulk around the base of the toilet, using a utility knife. Be careful not to damage the flooring. Wiggle the toilet from side to side to break its bond with the floor.
Pull the Toilet
Lift the toilet bowl straight up and off of the closet bolts to remove the toilet. If you didn't remove the tank, you might want to have a helper for this step. Be careful not to stress the tank bolts, which could crack the porcelain.
After removing the toilet, place it in a large, durable trash bag to keep any remaining water from dripping on the floor.
Clean up the Floor and Flange
Using a putty knife, remove all of the old caulking from the floor. Be careful not to damage the flooring. Remove the wax around the toilet flange, the plastic or metal fitting at the top of the toilet's drain pipe (where the closet bolts sit), and scrape away the residual wax as best as you can. You are now ready to install the new toilet.
Keep in mind that the new toilet may have a different footprint than the old one. If the new base is smaller, you may be able to see the outline of the old toilet. Clean all residue and discoloration so the outline of the old toilet is not visible; this is easiest to do when the toilet is removed, rather than after you've installed the new toilet.
