I like the first wallpaper, especially if it's on a narrow wall rather than a wide one.
I am planning a bathroom at the moment and am swinging between two extremes, either cool and refined, even slightly austere, like a posh boutique hotel or Victorian over-feminine, again like a posh boutique hotel. The feminine version would feature wallpaper on an end wall and geometric decorated tiles on the floor, along with pretty towels and lots of candles.
