I'm doing a new bathroom, with 9' ceilings. I'm planning on running crown moulding around the top, and this ideally will extend over the shower stall. the stall glass/door etc will not go all the way to the top, but I'm planning on having the tile go all the way up. how do i think about the crown? I've seen exa,plea where the crown sits right on top of the tile? any suggestions would be welcome! thx jp
