The Basics of Installing a New Toilet


Installing a new toilet isn’t super difficult but it’s good to know the process.

Nothing lasts forever—and that even applies to the porcelain titan, your toilet. Eventually, it may develop cracks or leaks that just aren’t fixable. Sometimes old toilets use too much water per flush. Whatever the reason, you may find yourself needing to replace your old toilet with a brand new one. A quality plumber like us at Mahon Plumbing can certainly help you get the job done, but if you want to know how the job is done, we’re here to shed some light on the process.

What Materials Are Needed?

Here are the things you’ll need to get that new toilet up and running:

  • That new toilet, of course!
  • Tools including an adjustable wrench and a screwdriver
  • Leveler
  • Wax ring
  • Toilet supply line
  • 2 Self-adjusting closet bolts

Basic Assembly

It’s easier to assemble the toilet before bolting it to your floor, so start off by doing that. Attach the tank to the toilet bowl and while you’re at it, attach the toilet seat as well. After this is done, it’s time to prepare the flange. Slip those two closet bolts into position on the flange then twist the washers on so those bolts are held in place tightly. Put the wax ring right on the flange. Now that your toilet is assembled, it’s time for installation.

Installing the Toilet

Hold the toilet over the flange and line up the holes with the closet bolts so you can simply press the toilet down against the floor. Using a level, check to see that your toilet is positioned correctly—if it isn’t, you may need toilet shims, steel washers, or even pennies to place underneath the base of the toilet to level it out. Then, take washers that came with the toilet and put them over the closet bolts. Tighten them and attach bolt caps so the bolts are no longer visible.

Hooking Up the Water Supply Line

Typically toilets use a water supply line that has a ⅜” connector. You’re going to attach the connector to the bottom of the toilet tank and water supply line, using your adjustable wrench to make sure all connections are secure and prevent any potential leaks. Now that it’s secure, you should be able to open the supply valve, let  the tank fill, and flush the toilet without any leaks. If necessary, you may need to adjust the fill valve. That’s how a toilet is installed!
