I'm doing a remodel of a bathroom in an older house. The existing bathroom was notched out of an existing bedroom, and the waste pipe goes through the exterior wall, meeting up with a waste stack for a downstairs bathroom. The supplies and waste were all just recently roughed-in by a plumber, with the exception of the exterior waste pipe (cast-iron).
The rough-in for the toilet is now very high -- a good 2 1/4" higher than the joist. My intent for the finished floor will add about 1 1/2", leaving about 3/4" difference. If the closet flange adds any height to the rough-in, then the difference will be even higher.
Can I saw off any part of the rough-in sanitary tee or flange to reduce this difference? The rough-in waste is PVC, which mates up to an old copper Tee then meets up to the cast-iron that goes through the exterior wall.
The plumber suggested raising the floor around the toilet, but I'm trying to avoid that, as I think it would be weird looking. I could raise the whole bathroom floor too, but that would end up WAY over the height of the adjoining bedroom floor, and I'd have to cut down my door to fit this new height. I guess the exterior waste pipe could be moved a little too, but I think that would be expensive, and would have to disturb the roof line of the bathroom downstairs, not to mention putting another whole in my asbestos shingle walls.
Any suggestions? If I do raise the floor just around the toilet, what's the best way to do this? Also, I've seen one forum that says that a sanitary tee can't be used horizontally, is that true? How would we fix this?
I will post pics to help clear up my descriptions.
Attaching pics of the plumbing rough-in. The shower is off to the right-side, out of the pic. The vanity will be on the left-side, and the vanity waste is what comes into the back of the sanitary tee. It comes in as 2", the closet comes down as 3", and the drain is 3". I'm not sure what size the cast-iron is.
