I got so sick and tired of sitting on a toilet that was the size of one you probably sat on when you were getting "potty trained". I had enough, bought a full size marine toilet a few years ago. No more feeling like your sitting on the floor, you can also do #1 and #2 at the same time, no more one or the other, but not both at the same time! Cost a lot, a real lot, first trip crew picked on me for spending that much, until, "it was their time". When they emerged from the head, they looked.......happy. They even go down there with the newspaper now (try that with a bucket). After the first trip, they never mentioned the cost again. It's the little things in life..
