Mine cost $10 and takes up less space and holds just as much shit as the round cans. Not as much as the one that fills up every nook and cranny but it doesn't require a loan.
Legal on the MF, not sure about the GC.
Not to put down the fine work of the toilet manufacturers but it's overkill for me.
You can see it here in between my girls.
Five gallon bucket. Free.
Gamma lid. $7
Toilet seat. $3 at building thrift store.
Milk crate. Free.
Watching my girls play run around the poop bucket for an hour while I drink gin and tonic. Priceless.
