I have been known to make some points out of weird things when I get hard up for some good rock, but think I'll pass on the urinals and toilet bowls. I've used old TV screens, floor tiles(not really all that bad) bottle bottoms and glass plates.
I found some old red glass plates not long ago and made a few small points from the bottom of them. Those were pretty thin but looked good...red glass is really hard to find around here.
