The design of a bathroom must account for the use of both hot and cold water, in significant quantities, for cleaning the human body. The water is also used for solid and liquid human waste to a sewer or septic tank. Water may be splashed on the walls and floor, and hot humid air may cause condensation on cold surfaces.
A shower may refer to a bath in which water is showered down on the body. A Showerhead is a fixture used for the act of bathing and a Shower Filter is a fixture used to remove chlorine & chloramines from shower water.
A walk in bathtub differs from a conventional bathtub in that not only is it smaller and deeper, but it also has an inward-opening or outward opening door which is self- sealing. Those with inward swing doors may require more water to fill as the tub must be larger to accommodate the door. An inward opening door may be considered a disadvantage due to the fact that emergency access is impossible since the pressure of the water on the door holds it closed.
Steam showers have become a more common bathroom fixture in recent years, primarily due to technical innovations resulting in lower costs, along with an overall increase in the appearance of luxury spa products in the bathrooms of middle and high income families.
Electrical appliances, such as lights, heaters and heated towel rails generally need to be installed as fixtures, with permanent connections rather than plugs and sockets. This minimizes the risk of electric shock.
In plumbing, a sink is a bowl-shaped fixture, usually made of porcelain (or, especially in the kitchen, stainless steel), that is used for washing hands or small objects such as dishes, nylons, socks or underwear. Old sinks were often made of enameled steel or cast iron.
A Belfast sink is a large ceramic sink with a traditional appearance, often set under work surfaces. An automatic sink is a sink fitted in a public restroom that is motion-sensored and detects motion beneath its surface.
From a decorating point of view the bathroom presents a challenge. Ceiling, wall and floor materials and coverings should be impervious to water and readily and easily cleaned. The use of ceramic or glass, as well as smooth plastic materials, is common in bathrooms for their ease of cleaning. However, such surfaces are often cold to the touch and so water-resistant bath mats or even bathroom carpets may be used on the floor to make the room more comfortable.
Today there are a wide variety of sauna options. Heat sources include wood, electricity, gas and other more unconventional methods such as solar power. There are wet saunas, dry saunas, smoke saunas, steam saunas, and those that work with infrared waves as described above.
