Installing a toilet may seem like a daunting task, but with the right tools and know-how, it can be a straightforward process. Whether you’re replacing an old toilet or installing a new one, this step-by-step guide will help you complete the job efficiently and correctly.

Tools and Materials You’ll Need:

  • New toilet
  • Wax ring
  • Adjustable wrench
  • Screwdriver
  • Closet bolts
  • Level
  • Shims
  • Bucket
  • Sponge
  • Towel

Step 1: Remove the Old Toilet

  1. Turn off the water supply: Locate the shut-off valve behind the toilet and turn it clockwise to shut off the water supply.                                                
  2. Flush the toilet: Flush the toilet to remove most of the water from the tank and bowl.
  3. Disconnect the water supply: Use an adjustable wrench to disconnect the water supply line from the bottom of the tank.
  4. Remove the bolts: Unscrew the nuts from the closet bolts located at the base of the toilet.
  5. Lift the toilet: Carefully lift the toilet off the closet bolts and set it aside.
  6. Remove the wax ring: Remove the old wax ring from the flange and inspect it for damage. Replace it if necessary.
  7. Clean the area: Use a sponge and bucket to clean the area around the flange, removing any old wax or debris.

Step 2: Install the New Wax Ring

  1. Prepare the new wax ring: Place the new wax ring on the flange, ensuring it is centered and properly seated.
  2. Install the closet bolts: Insert the closet bolts into the slots on the flange, making sure they are aligned properly.

Step 3: Install the Toilet

  1. Position the toilet: Carefully lower the toilet onto the closet bolts, ensuring that the bolts come up through the mounting holes in the base of the toilet.
  2. Secure the toilet: Place a washer and nut onto each closet bolt and tighten them evenly with an adjustable wrench. Be careful not to overtighten, as this can crack the toilet.
  3. Attach the water supply: Reconnect the water supply line to the bottom of the tank and tighten it with an adjustable wrench.
  4. Turn on the water supply: Turn the shut-off valve counterclockwise to restore the water supply to the toilet.

Step 4: Test the Toilet

  1. Check for leaks: Inspect the base of the toilet and the water supply line for any leaks. If you notice any leaks, tighten the connections as needed.
  2. Flush the toilet: Flush the toilet several times to ensure it is working properly and that there are no leaks.
  3. Check for stability: Sit on the toilet and gently rock back and forth to check for stability. If the toilet is unstable, use shims to level it.
  4. Adjust as necessary: Make any final adjustments to the toilet’s position and tighten the closet bolts and water supply line as needed.

Step 5: Finish Installation 

  1. Trim the closet bolts: Use a hacksaw to trim the closet bolts if they protrude too far above the nuts.
  2. Install the bolt caps: Place the plastic bolt caps over the closet bolts and snap them into place.
  3. Apply caulk: Apply a bead of caulk around the base of the toilet to create a watertight seal and improve the appearance.
  4. Clean up: Clean up any tools or debris from the installation process and dispose of them properly.

Congratulations, you’ve successfully installed a toilet! With proper care and maintenance, your new toilet should provide years of reliable service.
