Just as a note when Ken and I built out house the main thing we wanted was two toilets in the bathroom. We have his and hers. We still joke 9 years later that we can "do our thing" at the exact same time without leaving our bathroom.
Mine is very feminine with a oval top no squared off corners anywhere and his is a big squared off masculine model. People always comment on this they can tell which is which. Seriously we have loved having both it is very practical.
When Ken buys ugly items on trips (which those of you who have traveled with us have witnessed) the jug at the Monastery with Suzanne & Olivia for instance. Then I always say they will look great in his toilet. I looked in there the other day and he as a tiki from the Marquesas, the "jug" and a few other items on the floor. If we ever build again I think I will put shelves in his toilet for his treasures.
