What themes are popular for bathroom wallpaper designs?

Traditionally, bathrooms tend to have a nautical or watery theme, showing seaside elements, from light-houses to sea-horses, whales or seashells. Another favorite is a plant-based theme, using fern patterns, palm leaves, big jungle leaves or scatterings of leaf patterns. You don't have to follow those traditional ideas, or stick to a minimalist pattern that blends into the grey or white of the bathroom facilities. Decorators also like to use the unexpected or shocking - like a luxurious etoile or bright floral pattern, or a large modern cartoon image over four walls in bold colors. Choose what you will enjoy.
