A sauna is a small room often part of a bathroom or adjacent to a bathroom designed as a place to experience dry or wet heat sessions.
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 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.
Ground-fault circuit interruptor electrical sockets can reduce the risk of electric shock, and are required for bathroom socket installation by electrical and building codes in the United States and Canada. In some countries, such as the United Kingdom, only special sockets suitable for electric shavers are permitted in bathrooms.
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.
Modern bathtubs encompass an overflow and waste and may or may not have taps mounted on them. They may be built-in or free standing or sometimes sunken.
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.
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.
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.
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.
In the UK you can buy bathroom fixtures and accessories from Plumbworld, Cotswold Co and Roper Rhodes.
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.
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.
Walk in Bathtubs with outward swing doors can be more compact (holding about the same volume of water as a regular bathtub) and allow for emergency access or exit. There is no fear of the door seal allowing water to leak in either inward or outward swing doors.
In addition to acting as a normal shower, a steam shower produces water vapor using a humidifying steam generator. These types of showers provide a pleasant bathing experience that is becoming more and more popular in many countries.
