A toilet usually consists of two main parts: a bowl and a tank. It is best to first install the toilet bowl. Prior to installing the toilet bowl, check if the toilet closet flange has been temporarily plugged with insulation or a rag to prevent sewer gases from escaping. Remove this.  Next install the toilet bowl on top of the toilet closet flange to determine if it sits level. If it does not, prepare some shims to use later. Next remove the toilet bowl, and insert the toilet closet bolts approximately 2” long bolts into the slots on the toilet closet flange.

Place the toilet bowl onto the toilet closet flange. Make sure the bowl is well seated by rocking the bowl down. Once the toilet bowl has been seated, place a level on it and use the shims as necessary. Next, using nuts and washers tighten up the bolts.
