A full sized standard tub or combination shower and tub measures 32 inches by 60 inches. A standard toilet is 20 inches by 25 inches and the vanity is usually 19 inches deep and space will determine the width of the sink vanity. There are many small bathroom floor plans that easily incorporate these fixtures in a bathroom as small as 5 feet by 8 feet. Of course, a larger area naturally provides more options. An additional 2 feet of space will allow for a very useful linen closet, perhaps placed at the end of the tub. However, storage can be taken into account to include spacious medicine cabinets and narrow depth cabinets for the wall above the toilet. Lighting and ventilation must also be looked at ahead and if a window does not already exist, fluorescent lighting is available in abundant styles, some with ventilation fans incorporated into the design.
One of the most appealing things about the traditional bathroom is clutter gives it more of a lived-in effect, thus enhancing the traditional look. Don't be afraid to put plenty of pictures on the walls - black and white family portraits in gold frames are a good look. A chest of drawers or corner table with scented candles, aromatherapy oils or flowers will really bring the room to life. As a finishing touch an old style set of weighing scales, a large framed mirror or bulky traditional radiator will give the room that cozy old-fashioned feel.
As with the country and traditional bathrooms, cast iron baths are a must. Either a roll-top or slipper bath will do, and although you don't want holes or rust, the more dilapidated it looks the better. Even consider running sandpaper over the paint work and claw feet. It's always worth looking out for old fittings at antique shops and car boot sales.
