Step 1

Tools & Materials

Putty knife
Tank-to-bowl gasket
Attachment handles with nuts
Plastic washers
Bolt caps
Bowl-to-floor knobs
Wax ring
Water supply line
Toilet seat

Step 2

Removing the Old Toilet

Remove old toilet, rocking side by side to break seal.

Scrape flange clean and cover while working to block sewer gasses.

Square T-bolts for new toilet.

Pro Tip

In a four-person household, a 1.28-gallon toilet tank uses less than 7,000 gallons of water per year; a 1.6-gallon tank uses over 10,000 gallons per year.

For greater efficiency, get a toilet with a large outlet and flush valve which moves water faster and keeps bowl cleaner.

Step 3

Installing the New Toilet

Put wax ring on bowl, not on flange.

Set bowl over open flange.

Set tank on toilet and tighten attachment handles alternately by hand until you have china-to-china contact.

Attach water supply line by hand.

Pro Tip

Don’t over-tighten water supply nuts; this could break line and lead to flooding.
