Preparing the Floor and Closet Flange
Before installing your new toilet, inspect the floor and flange to ensure a solid, leak-proof setup.

Installing the New Toilet Bowl
Now you’re ready to install the toilet bowl with these steps:
- Insert brass closet bolts into the flange slots and slide on brass washers.
- Press the wax ring firmly flat-side down onto the flange.
- Carefully lower the toilet bowl onto the flange, aligning bolt holes with bolts.

- Place washers and nuts onto the bolts and tighten alternately, but avoid overtightening to prevent cracks.

- Slowly turn on the water supply and allow the tank to fill.
- Place a dry cloth around the base and check for leaks at all connections and the base.
- Flush the toilet several times to verify no water seeps from the wax ring or plumbing joints.
