I would like to move my toilet in my second floor bathroom so it is in the opposite corner of the current location. My problem is I don't know if it's even possible because I would have to go through 5-6 joists. My home is 100+ years old with 2x8 joists. I do have the option (if it even helps) if I can go through the joists to have the holes be over top of the sill plate (I think that's the right term) that is sitting on a block wall.
If someone could let me know if this can be done or if I'm totally out to lunch it would be great. I would most likely get a plumber in to do the job if it can be done.
