First: I have a floor Joist in exactly the wrong spot, and as a 10" or 14" rough-in toilet is about 3 times what a basic (Read Cheap) toilet cost, I have decided to solve this problem by setting the water closet back into the 2X6 stud wall. It is an Interior wall, so freezing will not be an issue. Is there any problem with this, other than asthectics...???
Second: I don't have a 4 1/2" hole saw bit for fitting the toilet mounting Flange through the floor. Is there any reason this can NOT be installed (the Hole) with a saws-all....?
