In the United States, "bathroom" commonly means "a room containing a toilet.” In America they are categorized as full bathroom, containing a bathtub, a shower, a toilet, and a sink; half (1/2) bath containing a toilet and a handbasin (lavatory); and 3/4 bath containing a toilet, a handbasin (lavatory) and a shower.
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 low-level access step is essential as is some form of built-in seat as part of a walk-in bathtub The addition of a shower curtain around the tub will make the walk in bathtub into a shower and bars or rails can be added to make the bathtub accessible for those with disabilities and for seniors.
A bathtub (or simply bath) is a plumbing fixture used for bathing. Most modern bathtubs are made of acrylic or fiberglass, but alternatives are available in the form of porcelain-coated steel or wood. Older western bathtubs are usually made of galvanized steel or iron. Traditional Japanese bathtubs were usually of a wooden construction.
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.
Steam showers are generally found in self-contained enclosures that don't allow the water vapor into the main part of the bathroom, thus avoiding damage to drywall, paint, or wallpaper. Most steam shower rooms are sold as stand alone shower units with between 12 and 30 jets, while many have additional features such as foot massagers, ceiling rain showers, radios, telephones, and CD players.
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.
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.
Sinks generally have faucets, usually cold and hot, and a drain. When a sink becomes stopped-up or clogged, a person will often resort to use of chemical drain cleaner or a plunger.
Jacuzzi is a company producing whirlpool bathtubs and spas. Its first product was a bath with massaging jets. The trademarked Jacuzzi name is commonly misused to refer to any bath with water jets, and can thus be considered a genericized trademark. Sometimes spas and hot tubs are also mistakenly referred to as Jacuzzis.
Until recently, most bathtubs were roughly rectangular in shape but with the advent of acrylic thermoformed baths, more and more shapes are becoming available. Bathtubs are typically white in color although many other colors can be found.
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.
Jacuzzis are commonly found in bathrooms in residential homes, hotels and aboard cruise ships and have become popular in high-end spas around the world. Jacuzzi products are distributed in about 60 countries.
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.
In its literal sense it means "a room with a bath", but as bathtubs have partly made way for showers and steam showers, the more general sense of "a room where one bathes" makes more sense. There can be just a shower or just a bathtub or both, sometimes combined and sometimes separate (in which case the bathtub may have a second shower). Usually, it also contains a handbasin or sink and often also a toilet.
