How to Install a Toilet Seat


Toilet seats are a bathroom plumbing fixture that has a long lifespan. Many people get decades of use from their toilet seats with only minor problems popping up such as replacing the wax ring or interior toilet parts. However, if the toilet starts to wiggle from side-to-side or the bowl becomes stained or cracked, it’s likely time for a new toilet seat.

Toilet replacement isn’t a difficult job, and it’s something handy homeowners might want to try their hand at. Of course, we always recommend professional toilet replacement because it protects your investment and ensures the new toilet’s installed correctly. That being said, if you want to attempt to install a toilet yourself, here are some tips:

Begin with a Clean Area

Give yourself plenty of room to work. Remove any items around the toilet and clean the toilet before removing it. Use an antibacterial cleaner to sanitize the hinge and toilet bowl area and the toilet seat. Bacteria and viruses live on toilet seats, and you’ll be quite up-close and person during the removal process.

Gather Your Tools

Next you want to get all your supplies ready. Having everything within reach makes the job go faster and staves off frustration. You’ll need the following tools:

  • Lubricating oil
  • Tape measure
  • Adjustable wrench or a pair of pliers
  • Flathead screwdriver
  • Toilet seat kit

Once you have all your tools, it’s time to start the installation process.

DIY Toilet Installation

  • The toilet seat connects to the bowl with bolt caps. You need to remove these using the flathead screwdriver. If there aren’t any bolt caps, loosen the nuts using the adjustable wrench.
  • Next remove the bolts. Sometimes the bolts are hard to get out because there is years of rust or grime on them. Use your lubricating spray to make this part go easier.
  • Once you remove the bolts, take off the toilet seat and hinges. Get rid of all the old pieces.
  • Line up the new hinges on the new seat where the old hinges were.
  • Put the bolts into the hinges’ holes and make sure that the head of the bolt points up.
  • Thread the nuts onto each bolt and then use the adjustable wrench to tighten more.
  • Did the toilet kit include plastic caps? If so, snap them into place over the hinges. Press them down to make sure they’re secure.
