feng shui can be applied to any number of areas I designed a garden on feng shui principles for example. the bog seat thing is more to do with having negative area in one of the points of influence , by closing the lid you close off an area where energy flows can get caught up in a negative zone, Especially inportant if the toilet is positioned in an important area for wealth or romance etc the link explains it better

Yeah but if the lid is up and there's wee on the other bit, you may touch it when putting the seat down, meaning you get someone elses wee on your hand . . .yuck
