Title says it all. Who knew there were so many options - seat height, gpf, flush technology, etc. I like the idea of the "comfort height" toilets, which I think is different handicap height ones. I have a small bathroom, but will likely switch from the existing round to elongated. Beyond that, I dunno. I'm not really understanding the difference between $100 and $400 crappers. It seems like I can get a pretty good Kohler for under $200. I just want to make sure I'm not missing some great pooper feature. Mods: I couldn't find "smelly things" so I am posting in shiny things.
