If you are setting up a new toilet in a new place, you will need to run (or have someone run) a water supply line and a drainpipe, which must be connected to the drain or vent system in compliance with code, or even if you are just replacing an existing toilet, you should replace the water supply tubing as well.

Replace A Toilet In Your House.

Required Tools:

  • Hacksaw
  • Slip-joint pliers
  • Putty knife
  • Rubber gloves
  • Adjustable wrench
  • Rag
  • Plunger
  • Caulk gun (if needed)

Required Materials:

  • Two-piece Toilet
  • Plumber's Putty (if needed)
  • Supply Tube
  • Toilet To Floor Bolts
  • Toilet Seat
  • Flange (if needed)
  • "No-Seep" Wax Ring
  • Shut Off Valve

Step 1: Disconnect with the water supply.

After shutting off the water, flush the toilet to clean off most of the water from the tank and bowl. A little water will still remain in the bowl. Use a force-cup plunger to force it down the drain line. Remove the water left from the tank with a sponge and a bucket. Disconnect the supply line from the base of the tank.

Step 2: Remove the old toilet.

To remove the old toilet, pop off the trim caps at the base of the toilet. Then, loosen and remove the nuts and washers on the closet bolts securing the bowl to the floor. If the nuts are rusted, you might need a hacksaw to cut them off.

Now that you've removed the nut and washer on each side of the bowl, gently move the toilet back and forth until you can lift it free. Once you've removed the toilet, there will be an open line to the sewer system. Put a rag into the hole to stop sewer gases from running up into your house and to prevent stuffs from falling into the hole.

Tip for you: If you are working alone, disconnect the tank from the bowl before disconnecting and removing the bowl. Lifting the two pieces separately will be much more easy.

Step 3: New wax seal installation.

A putty knife will be used to pry up and remove the old wax seal. Check the flange beneath the seal to ensure it is not cracked. If you've inspected the flange, take the rag from the hole. Once the flange is damaged, get help from a plumber. If the flange is fine, remove the rag from the hole and take the closet bolts out of the flange. Set the new wax seal and hook the new closet bolts into their slots on the flange.

Tip for you: Remove the rag before installing the new wax seal. Leaving it in is a common and costly mistake.

Step 4: Attach the bowl and tank.

With the closet bolts and seal are ready, you can attach the tank and bowl together to set up the new toilet. Slip the tank bolts through the opening in the bottom of the tank. Line up the shank of the bolts with the holes in the bowl and drop the tank into place. Secure the tank to the bowl by tightening a nut onto each tank bolt. Evenly tighten all the nuts until the tank stays firmly on the bowl. Be careful not to over tighten the bolts and crack the toilet. Get the right balance between sealed and too-tight.

Tip for you: The toilet used in your project weighed around 120 pounds. Make sure to have enough help on hand to move, lift and place it or any other heavy item for your own safety.

Step 5: Install the toilet and hardware.

In this step, you have to secure your toilet and complete the installation. Set the assembled toilet onto the flange assembly, you have to ensure that the closet bolts protruding from the floor line up with the holes in the base. Slightly press the toilet in place to form a good seal with the wax ring.

Put a couple of washers and a nut on each bolt. Secure the nuts with a small wrench but please do not over tighten them. If the bolts extend too far over the top of the washers and nuts, use a hacksaw to cut off the excess.

Pop the trim caps in place to cover the ends of the bolts. Secure the new seat and lid to the bowl with mounting bolts. Then, a slip-joint pliers will be used to reconnect the water supply line to the bottom of the tank.

Step 6: Connect the water supply.

Wrap the threaded connectors with Teflon tape and link back the water supply to the toilet according to the instructions of manufacturer. Turn on the water at the supply shut-off and allow the tank to fill. Check for leaks and adjust the fill valve so that the water meets the fill line.

Tip for you: Keeping toilets in good repair condition will help you save your budget. Just a small leak may waste as much as 40 gallons of water per day.

Step 7: Caulk the Base (Optional) 

Caulk around the base of the toilet to ensure a good seal. Beside that, you can choose to caulk the base of the toilet or not. On the one hand, caulking the whole base can lead to undetected water leaking for some time. On the other hand, caulking the base can make for a more polished look. If you make the decision to caulk the base of the toilet, leave a gap or “weep hole” on the backside, in case of the water leaking, you will find it sooner.
