I am planning to install my new bathroom subfloor today. I have a 3" PVC riser for the toilet, and I originally cut a 4 1/4" hole. I had seen 4” - 4 1/4” recommended when I was reading other posts. The flange will fit fine, but I realized that I will have a difficult time getting primer and cement applied. I am wondering if I should have used 4 1/2", but I just want to make sure I don't go too large (which I know is bad). I am going to wait until the tile is in place before gluing the flange, so that it sits on top of the finished floor.
Here is a picture with a dauber for reference. This is a larger dauber, so perhaps with one from the smaller cans, I can make it work. I've also seen that they have brushes, so maybe I could use one in this instance. In hindsight, I wish that I had asked my plumber to use a 4x3 closet elbow, so that he could have stubbed up a 4" riser and I could have used an inside flange.
I appreciate any advice!
