Showers need to cover a certain diameter around you as you bathe, for the water to fully wet your body. The size of the bathroom should therefore determine the type of shower used, and electric showers ought to be generally used in capacious bathrooms as they require special installations. Shower enclosures can help space out the area for bathing and other ablutions such as brushing and washing, creating an economic and convenient bifurcation within the bathroom. Different types of shower enclosures include the quadrant shower enclosures (which come in 800, 900 or 1000 mm) and the curved shower enclosures (meant to be used in curtailed bathroom areas), though wet rooms, wherein there is no enclosure involved and the shower space is at level with the rest of the bathing area, is the most basic and suitable. Wet rooms have a slope for water disposal and water-proof tiles to prevent water seeping. A walk in shower is built on a wet room, and it is available in side panel, walk through, as well as side and end panel designs. Shower doors, necessary to cordon the water overflowing from the enclosure so that it goes only down the plug-hole, are classified on the basis of their of their fixture to the enclosures. Hinged shower doors eat up a lot of space, whereas bi-fold shower doors are made of folding panels and so conserve area. Quadrant shower doors are one or two in number and these are sliding or hinged; their use depends on the size of the quadrant shower trays, which are the bottom floor within the quadrant enclosure. Offset quadrant shower doors open sideways on rollers or outward on hinges.
