How to Install a Toilet Flange Spacer
Toilet flange spacers are used when there is a discrepancy between the level of your floor and the base of the toilet. These are most often employed when a new tile floor has been laid in a bathroom, leaving the closet flange (the sewer opening in the bathroom floor) below floor level. Installing a toilet flange spacer on top of the existing flange will bring it up to the level of the rest of the tile, allowing for an even foundation for a new toilet.
Clean off the closet flange area. Scrape up any old putty with the putty knife and clean any remnants of previous wax rings with a rag and alcohol. Clear away any dirt or construction debris to give the toilet a solid foundation.
Install the closet flange bolts. Insert the T shaped end of the bolt into the slot on the closet flange. Turn the bolt so that the T locks it in place in the slot.
Slip the flange spacer over the closet flange and the bolts.
Press the wax ring into place on top of the spacer.
Turn the toilet bowl over. Roll out a thin strip of plumber's putty. Press this into place along the bottom of the bowl. Turn the toilet bowl back over but hold it up so that the putty doesn't rub against the floor. Have a friend or assistant help you if it is heavy.
Guide the toilet bowl so that it fits over the flange, aligning the outlet in the bottom of the bowl with the sewer inlet in the flange, while, at the same time, ensuring that the flange bolts poke up through the holes in the base of the toilet.
Press the bowl firmly against the floor to seal.
Slip the plastic and metal washers over the flange bolts. Thread on the flange nuts and tighten with the wrench.
