I must get a heated seat for home.. you simply can't imagine!
In Japan I was familiar with toto, the toilet room is in fact called the toto.
In large department stores there the seats automatically flush, and cover the seat with a new plastic sterile liner. It's on a tube that shifts it's way over the toilet seat..
I think it's a nice feature.
This is one, I am not sure how many the park has of the Bio Toto, but this was at Cougar Mountain Campsite.
