How To Install A New Toilet

Posted on: 16 August 2017

Whether your old toilet is leaking, uses too much water, or is outdated, you can replace that old toilet and install a new one yourself. This is a fairly simple job, but it may require an extra pair of hands to help you carry the toilet and guide it in it's place. See below for instructions on how to install a new toilet.

Tools And Materials For The Job:

  • New toilet
  • Crescent wrench
  • Wax ring
  • Level
  • New water supply line
  • Towels
  • Screwdriver
  • Bucket


  1. Remove the old toilet by turning off the water at the back of the toilet. Then flush the toilet to get rid of as much water as you can from the toilet bowl and from the reserve.
  2. Next, remove the bolts holding the reserve tank to the bowl. Use a bucket to drain out any more water that may be inside. When the water is out, haul the tank out of your home.
  3. Now you can begin removing the bowl. To remove the bowl, you'll have to remove the nuts around the bolt in the floor (holding the base of the toilet in place). Pull up on the toilet base and set it to the side. 
  4. Remove the wax ring that was below the base and stuff a rag into the pipe in the floor to prevent the sewer smells from coming out into your home. Once the rag is in place, take the bowl outside of your home as well.
  5. Take your new wax ring and set it in place (after you take out the rag).
  6. Set the base of the toilet in place over the wax ring, lining up the bolts with the new base.
  7. Once the base is set, use the level to level the toilet base and make any necessary adjustments. You can use shims to help get the toilet level if you need to.
  8. After the toilet is level you can install the tank to the back of the toilet and add the new water line.
  9. Turn the water back on and allow the tank to fill up with water. Flush the toilet to test out your handy work and look for any leaks around the toilet.

The toilet is one of the most used seats in the house, so it can wear out over time. Call a professional plumber if you need help or more information on various plumbing repairs.
