When the bathroom became a standard part of the house in the 19th century, the bathroom was very plain and almost sterile in appearance and white was the dominant colour. Gradually, as the century progressed and became the next, the décor followed that of the time, though white still remained a colour associated with bathrooms. When you design a bathroom, the décor and the space must be considered.
The space is very important. If the room is small, then this will affect the design of the bathroom. Make a floor plan of the space by making a to-scale drawing on graph paper. The squares will each equal an inch. By doing the drawing, you will be able to figure where everything will go, whether you will have room for the bath shower, the bath cabinets, the toilet and the sink. More than one person using the bathroom Keep in mind the flow of the room or how it will be used. The sink can be across the room from the toilet, for example. Try to take into account that perhaps more than one person might be in the bathroom at the same time and allow for that as well.
The bathroom fixtures are next. These will also be affected by space as well. If the bathroom is small, then space-saving toilets and sinks are available. Perhaps, the sink will have to be pedestal sink rather than a sink and a vanity. A shower If there is room enough for a shower, perhaps you will have to go with a shower stall than a shower and bath combination. If there is enough room for a bath, then the style of the bath should be considered.
The décor of the house should reflect the house's overall style. If it is Victorian, then like the bathrooms of the period, the bathroom could be plain with a lot of white and some black - especially in the tiles. If it is a thirties house, then you can add colours such as robin's egg blue, pink, yellow and light green. If the house is modern, then anything goes. It could be any style or a combination of many. When you design your new bathroom, try to tie in all the elements: the space, the fixtures and the décor to create a room that works well together, no matter the size.
