Flange Extender

I didn't do any tile in the bathroom today, rather I started to deal with some outstanding issues. One of which was the toilet flange. The toilet flange should sit on top of the tile, but the cast iron flange in my bathroom sits level with the floor because I built the floor more than 1/2" with the cement board, mortar, tile, etc. Given this, I needed an extender. My cast iron flange is a bit weird because it's offset, and the only thing I could find to fit it well was the Sioux Chief gasket flange. I checked it out today, and it seems like it will work. I was concerned about the PVC on cast iron, but according to the manufacturer these piece was designed to sit on top of cast iron flanges. I guess we'll see tomorrow. The red gasket at the bottom makes the flange fit snug, and I'll be sealing the PVC to the cast iron flange with some adhesive silicon, and bolting both the original and extender flanges together to make sure they're solid.
