I have a quick question.....I am finishing my basement and I have tiled the bathroom floor. I have the 4" pipe sticking out of the concrete. Do I cut the pipe level with the floor and then install a 4x3 toilet flange? If it is cut f\level with the top of the tile, it will be about 3/4" up from the concrete floor. Does this sound correct?
Cut the pipe off flush with the floor. Glue in a 4X3 FLUSH flange. That is a flange without the lip on the bottom where it glues into the pipe. If you use a regular flange it will sit up too high. You want the bottom of the flange sitting on the top of the tile.
