There may be times when you need to replace a bathroom toilet fixture. Perhaps the existing toilet is broken or cracked, or you may want a different style for a bathroom makeover because the old harvest gold toilet from 1972 clashes with your new garden wall decor or flowers wall decor. While you may need a professional to install a toilet in a new bathroom that was not previously plumbed, replacing an existing toilet is a job that is well within the skill set of an average do-it-yourself homeowner. Generally, the project will require basic tools and about an hour of your time.
Supplies Needed
Of course, you will need to purchase the new toilet and a wax ring with anchor bolts. You will also need a level and an adjustable wrench. When you purchase the toilet, take the time to thoroughly inspect it for cracks or chips and then transport it in a way that won’t damage the bowl or the tank.
Remove the Old Toilet
To remove the old toilet, start by turning off the water supply lines; flush the toilet a few times to remove any excess water. A sponge or old towels can be used to sop up any residual water in the tank or bowl. If there is any caulking around the base of the toilet, loosen it with a utility knife. Disconnect the water lines and unscrew the bolts that mount the toilet to the floor and lift the whole unit, preferably with help. Keep the toilet as level as possible to minimize spillage of water from the inner workings of the toilet and set it in a plastic bag or tub, then remove it from the house.
Scrape away any remaining caulk and any remnants of the previous wax ring to level the floor before installing the new toilet. You’ll be able to see the flange from the old toilet. New flange bolts should be included with the new wax ring: Set the flange bolts in place in the flange so that they are sticking straight up, then set the wax ring in between the two flange bolts, centered on the flange. With help, carefully lower the new toilet down onto the wax ring, making sure that the flange bolts are lined up and come through the openings on the base of the toilet. Gently set the toilet down on the wax ring; to seat the wax ring, gently sit on the toilet to press the toilet into the wax ring. Next, evenly tighten the flange bolts on both sides of the toilet, but do not over-tighten them: Note that the flange bolts do not hold the toilet down, they just keep it from sliding or moving. Check that the toilet is even and level by using a level; if necessary, carefully adjust the level with the flange bolts.
Attach the tank to the toilet: Turn the tank upside down, attach the rubber gasket and then set the tank back on top of the toilet. Next, attach the screws: On the inside of the tank, you’ll find three screw holes. Attach the screws with the rubbers on the inside of the tank. Then on the bottom side of the tank, where the screws come through the toilet, slide the rubber onto the screw, then the washer and then the nut. Tighten everything evenly taking care not to over-tighten.
Finally, reattach the water lines and turn the water on slowly and check for leaks; tighten and adjust the water line bolts as needed. Let the tank refill and flush to check that the wax seal is properly seated and then run a bead of caulk along the perimeter of the toilet where it meets the floor.
