It's funny peculiar, not funny haha. No toilet humor here. In renovating the 345 we just purchased I removed the toilet and the ten inch riser that it was placed upon by the PO, which put the toilet seat 26 inches above the floor! The riser was necessary because the three inch pipe that goes into the holding tank is about seven inches from the back wall in our coach and the toilet required an eleven inch spacing from the wall. So the PO had installed two 45 degree elbows to accomplish this but the elbows required the need for the riser.
So, what am I missing here? The ten inch riser is not factory and it seems that RV toilets require eleven inches from the back wall to the center of the sewer pipe/toilet flange. Was the factory Airstream toilet different? I can't seem to find a toilet that requires only seven inches to the wall. Has anyone encountered this before? What is my solution here?
