Huge bathroom with a wall-sized window, stylish plank beds and view of veranda with Japanese rock-garden is impractical dream for the large majority of us. In limited urban environment all we often have is just four-squared box. And even rather large bathroom sometimes is not enough for realization of all our design plans. As well-known stepmother from a fairy tale "Cinderella" had said - "The kingdom is small, there is no room to be on the loose". You can't enlarge your bathroom even at the expense of your neighbours because of chief wall. But maybe it's better to solve this problem with the help internal reserves and to expand your bathroom environment visually? Maybe, it'd be better to help out missing square meters just virtually, by creation of their visibility?
Design. You've got to start with bathroom design for competent disposal of available space. Development of modern installation systems allows placing of all bathroom and lavatory equipment not in its common places but in places where you need it to be; you can save some tens of inches or even a few meters and free some space visually. For example, you may save some space with angular installation of not only bath and shower cabin, but wash basin or toilet bowl. The bath or shower cabin may be completely or partially hidden in a niche if such technical feasibility is available.
Bathroom and lavatory equipment. If space available is not as huge as you want, you can easily save it by choosing of small bathroom equipment specially designed for small bathrooms which consumes much less space than standard equipment. In that case the doll's house effect is triggered and the environment around diminished pieces of equipment seems to be larger. By the way, many people think that space-saving toilet bowls and bidet are even more convenient, than standard ones. Of course you can't say that about a small wash basin or a bath. Hanging bathroom equipment is of interest, too, as it visually frees some space; bathroom equipment like "two in one", for example, tandem of shower and bath, is popular as well.
Walls. The walls play the most important role in visual enlargement of bathroom space. You should never use shadow toned ceramic tile and other types of covering in small rooms, especially in combination with large decors and wide borders. The tile is to be light toned. In was considered for a long time that large ceramics was to be used in small rooms. Nevertheless, practice shows, that mosaic makes even a small room visually larger.
Necessary effect of depth is achieved with ceramic tile and furniture of light, deep tones and shades in combination with medium-sized and soft-core decor, narrow decorative borders especially placed not horizontally, but vertically. Panels are outside the fold, even the large ones, but only those including perspective view: landscapes, especially marine, imitation of view from a window, the sky and so on. Your look does not die against them but flies away. Photo panels are the latest thing in decoration of rooms.
