Step 1: Remove the Drain Cover

Note: The toilet installed in this project was fully assembled. If installing a toilet that's not already assembled, read and follow the manufacturer's instructions for assembly.

Remove the drain cover from the toilet drain. Make sure there is no residue from the old wax ring or caulk remaining.

Step 2: Install the Wax Ring and Closet Bolts

Carefully unwrap the wax ring and center it on the toilet flange. This ring compresses under the weight of the toilet to form an airtight, watertight seal.

Slip the closet bolts into place in the toilet flange. Try to position them so they will line up easily with the bolt holes on the toilet base.

Slip a nylon washer over each closet bolt, sliding it down to the bottom of the bolt.

Step 3: Position the Toilet and Finish Installation

Lift the toilet over the drain and gently set it into place with the closet bolts coming up through the bolt holes in the toilet base.

Note: This part of the toilet installation always works better with a helper. Toilets are heavy, and it's hard to see the closet bolts when lifting the toilet into place. Try to have a second person on hand to do the heavy lifting or to guide the toilet into position.

Slip a nylon washer over each closet bolt, followed by a metal washer and a nut. Tighten down with an adjustable wrench. Be careful: Over-tightening can crack the toilet base.

Attach the water supply line to the toilet, turn on the water at the shutoff and let the toilet tank fill.
