Sheila, are you thinking to separate the bowl and tank and bury the bowl like that ... and then do something else with the tank? As I said, I hate to throw away things like this that I know are not biodegradable. I know they will smash them at the dump, but still, the pieces aren't readily biodegradable either. I really would like to repurpose it, if I can. I'm liking the idea of a "throne" bed.
