On what model throne do you do your two?

[AFTT47]

I never paid attention to make and model but maybe I should have. They always seem inadequate. I'm afraid I make heavy demands on a toilet.

It would be helpful if toilets were of standard shapes and sizes so they could be matched with a plunger. Perhaps most people haven't noticed but some plunger shapes are not compatible with certain bowl shapes. This is known to me because of my aforementioned heavy demands on toilets, often necessitating the need of a plunger.
