A bathtub, also abbreviated as bath or tub, is a container for holding water in which a person or another animal may bathe. Modern bathtubs can be made of thermoformed acrylic, porcelain-enameled steel or cast iron, or fiberglass-reinforced polyester. A bathtub is usually placed in a bathroom, either as a stand-alone fixture or in conjunction with shower plumbing.

👉 Bathtub in the context of Bathroom
A bathroom is a room in which people wash their bodies or parts thereof. It can contain one or more of the following plumbing fixtures: a shower, a bathtub, a bidet, and a sink (also known as a wash basin in the United Kingdom). A toilet is also frequently included. There are also specific toilet rooms, only containing a toilet (often accompanied by a sink), which in American English tend to be called "bathrooms", "powder rooms" or "washrooms", as euphemisms to conceal their actual purpose, while in British English they are known as the "loo," "water closet" or "WC", or just "toilets" or possibly "cloakrooms" - but also as "lavatories" when they are public.
Historically, bathing was often a collective activity, which took place in public baths. In some countries, the shared social aspect of cleansing the body is still important, for example with sento in Japan and, throughout the Islamic world, the hammam (also known in the West as a "Turkish bath").

Bathtub in the context of Greywater
Greywater (or grey water, sullage, also spelled gray water in the United States) refers to domestic wastewater generated in households or office buildings from streams without fecal contamination, i.e., all streams except for the wastewater from toilets. Sources of greywater include sinks, showers, baths, washing machines or dishwashers. As greywater contains fewer pathogens than blackwater, it is generally safer to handle and easier to treat and reuse onsite for toilet flushing, landscape or crop irrigation, and other non-potable uses. Greywater may still have some pathogen content from laundering soiled clothing or cleaning the anal area in the shower or bath.
The application of greywater reuse in urban water systems provides substantial benefits for both the water supply subsystem, by reducing the demand for fresh clean water, and the wastewater subsystems by reducing the amount of conveyed and treated wastewater. Treated greywater has many uses, such as toilet flushing or irrigation.
Bathtub in the context of Hard water
Hard water is water that has a high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.
Drinking hard water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water.
Bathtub in the context of Hydrotherapy
Hydrotherapy, formerly called hydropathy and also called water cure, is a branch of alternative medicine (particularly naturopathy), occupational therapy, and physiotherapy, that involves the use of water for pain relief and treatment. The term encompasses a broad range of approaches and therapeutic methods that take advantage of the physical properties of water, such as temperature and pressure, to stimulate blood circulation and treat the symptoms of certain diseases.
Various therapies used in the present-day hydrotherapy employ water jets, underwater massage and mineral baths (e.g. balneotherapy, Iodine-Grine therapy, Kneipp treatments, Scotch hose, Swiss shower, thalassotherapy) or whirlpool bath, hot Roman bath, hot tub, Jacuzzi, and cold plunge.
Bathtub in the context of Reuse
Reuse is the action or practice of using an item, whether for its original purpose (conventional reuse) or to fulfill a different function (creative reuse or repurposing). It should be distinguished from recycling, which is the breaking down of used items to make raw materials for the manufacture of new products. Reuse—by taking, but not reprocessing, previously used items—helps save time, money, energy and resources. In broader economic terms, it can make quality products available to people and organizations with limited means, while generating jobs and business activity that contribute to the economy.
Bathtub in the context of Drowning
Drowning is a type of suffocation induced by the submersion of the mouth and nose in a liquid. Submersion injury refers to both drowning and near-miss incidents. Most instances of fatal drowning occur alone or in situations where others present are either unaware of the victim's situation or unable to offer assistance. After successful resuscitation, drowning victims may experience breathing problems, confusion, or unconsciousness. Occasionally, victims may not begin experiencing these symptoms until several hours after they are rescued. An incident of drowning can also cause further complications for victims due to low body temperature, aspiration, or acute respiratory distress syndrome (respiratory failure from lung inflammation).
Drowning is more likely to happen when spending extended periods near large bodies of water. Risk factors for drowning include alcohol use, drug use, epilepsy, minimal swim training or a complete lack of training, and, in the case of children, a lack of supervision. Common drowning locations include natural and man-made bodies of water, bathtubs, and swimming pools.
Bathtub in the context of Shower
A shower is a place in which a person bathes under a spray of typically warm or hot water. Indoors, there is a drain in the floor. Most showers are set up to have adjustable temperature, spray pressure, and showerhead nozzle angle. The simplest showers have a swivelling nozzle aimed downward, while more complex showers have a showerhead connected to a hose that has a mounting bracket; this allows the showerer to hold the showerhead by hand to spray the water onto different parts of their body. A showerhead can be installed in a small shower stall or bathtub, with a plastic shower curtain or door.
Showering is common due to the efficiency of using it compared with using a bathtub. Its use in hygiene is, therefore, common practice.
