How to Install a Toilet

Installing a toilet might seem like a daunting task, but fear not! With a little guidance and the right tools, you’ll be able to tackle this home improvement project with confidence. In this friendly article, we’ll take you through the step-by-step process of installing a toilet, ensuring that you have a smooth and successful experience.

Step 1: Gather Your Tools and Materials

Before you start, it’s essential to have all the necessary tools and materials at hand. Here’s a list of what you’ll need:

  1. New toilet
  2. Wax ring or toilet gasket
  3. Adjustable wrench
  4. Screwdriver
  5. Level
  6. Hacksaw (if needed)
  7. Closet bolts and washers
  8. Water supply line (if required)
  9. Plumber’s tape
  10. Sponge or rags

Make sure you have everything ready to go before diving into the installation process.

Step 2: Remove the Old Toilet

To begin, shut off the water supply to the existing toilet. Then, flush the toilet to remove as much water as possible. Use a sponge or rags to soak up any remaining water in the tank and bowl. Next, disconnect the water supply line and unscrew the bolts securing the toilet to the floor. Carefully lift the old toilet off the flange and set it aside.

Step 3: Prepare the Flange and Measure

Inspect the flange (the pipe fitting on the floor) to ensure it’s in good condition. Remove any old wax or debris using a putty knife, and check if the flange is at the correct height. If the flange is too low, you may need to use a flange extender or a double wax ring. Measure the distance between the center of the flange and the wall behind it. This measurement will help you position the new toilet correctly.

Step 4: Install the Wax Ring or Toilet Gasket

Place the wax ring or toilet gasket onto the flange, making sure it is centered. If you’re using a wax ring, it’s a good idea to warm it up by rubbing it between your hands before placing it. This helps ensure a better seal. Some toilets may require a specific type of gasket, so refer to the manufacturer’s instructions if needed.

Step 5: Position and Secure the New Toilet

Carefully lift the new toilet bowl and align the mounting holes at the base with the closet bolts on the flange. Gently lower the toilet, ensuring the wax ring/gasket is properly seated and compressed. Once in position, press down firmly to create a good seal. Place washers and nuts onto the closet bolts, tightening them alternately until the toilet is secure. Be cautious not to overtighten, as it may crack the porcelain.

Step 6: Connect the Water Supply

Reconnect the water supply line to the bottom of the toilet tank, ensuring it’s tightened securely but not overly tight. If your new toilet doesn’t come with a supply line, you may need to purchase one separately. Apply plumber’s tape to the threaded connections to prevent leaks. Once connected, turn on the water supply and check for any leaks around the fittings. Tighten as needed.

Step 7: Test and Adjust

With the water supply on, give your newly installed toilet a test flush. Observe the water flow and ensure it fills and flushes properly. Use a level to check if the toilet is balanced and adjust as necessary by inserting shims under the base. When the toilet is stable and level, trim off any excess closet bolts using a hacksaw.


Congratulations! You’ve successfully installed a toilet.
