Large container for holding water in which a person may bathe

A bathtub, also known simply as a bath or tub, is a container for holding water in which a person or another animal may bathe. Most modern bathtubs are made of thermoformed acrylic, porcelain enameled steel or cast iron, or fiberglass reinforced polyester. A bathtub is placed in a bathroom, either as a stand alone fixture or in conjunction with a shower. Modern bathtubs have overflow and waste drains and may have taps mounted on them. They are usually built in, but may be free standing or sometimes sunken. Until acrylic thermoforming technology permitted other shapes, virtually all bathtubs used to be roughly rectangular. Bathtubs are commonly white in color, although many other colors can be found. Two main styles are common:
Western style bathtubs in which the bather lies down. These baths are typically shallow and long. Eastern style bathtubs in which the bather sits up. These are known as furo in Japan and are typically short and deep.

Documented early plumbing systems for bathing go back as far as around 3300 BC with the discovery of copper water pipes beneath a palace in ancient Europe. Evidence of the earliest surviving personal sized bath tub was found on the Isle of Crete where a long pedestal tub was found built from hardened pottery. The clawfoot tub, which reached the apex of its popularity in the late 19th century, had its origins in the mid 18th century, when the ball and claw design originated in the Netherlands, possibly artistically inspired by the Chinese motif of a dragon holding a precious stone. The design spread to England, where it found much popularity among the aristocracy, just as bathing was becoming increasingly fashionable. Early bathtubs in England tended to be made of cast iron, or even tin and copper with a face of paint applied that tended to peel with time. The Scottish born inventor David Buick invented a process for bonding porcelain enamel to cast iron in the 1880s while working for the Alexander Manufacturing Company in Detroit. The company, as well as others including Kohler Company and J. L. Mott Iron Works, began successfully marketing porcelain enameled cast iron bathtubs, a process that remains broadly the same to this day. Far from the ornate feet and luxury most associated with clawfoot tubs, an early Kohler example was advertised as a "horse trough/hog scalder, when furnished with four legs will serve as a bathtub." The item's use as a hog scalder was considered a more important marketing point than its ability to function as a bathtub. In the latter half of the 20th century, the once popular clawfoot tub morphed into a built in tub with a small apron front. This enclosed style afforded easier maintenance and, with the emergence of colored sanitary ware, more design options for the homeowner. The Crane Company introduced colored bathroom fixtures to the United States market in 1928, and slowly this influx of design options and easier cleaning and care led to the near demise of clawfoot style tubs. In the 1960s fiberglass bathtubs became the standard for homes, being lightweight and inexpensive. James R. Wheeler and his brother Richard in 1979 adapted the acrylic being used for outdoor spas to make acrylic bathtubs. Working with Spartech Plastics, they developed the modern co extruded and durable acrylic bathtub. The company American Bath Factory was the first to expand the diversity of acrylic bathtubs to include whirlpools, clawfoot bathtubs, and a large variety of pedestal and modern bathtubs. The process for enamelling cast iron bathtubs was invented by the Scottish born American David Dunbar Buick.

Pedestal tubs rest on a pedestal in what many would term an art deco style. Evidence of pedestal tubs dates back to the island of Crete around 1000 BC.

A baby bathtub is one used for bathing infants, especially those not yet old enough to sit up on their own. These can be either a small, stand alone bath that is filled with water from another source, or a device for supporting the baby that is placed in a standard bathtub. Many are designed to allow the baby to recline while keeping its head out of the water.

Hot tubs are common heated pools used for relaxation and sometimes for therapy. Hot tubs became popularized in the U. S. during the early hippie era (1967–1980), appearing in films and music.

Whirlpool tubs first became popular in the U. S. during the 1960s and 1970s. A spa or hot tub is also called a "jacuzzi" since the word became a generic after plumbing component manufacturer Jacuzzi introduced the "Spa Whirlpool" in 1968. Air bubbles may be introduced into the nozzles via an air bleed venturi pump.

Freestanding tubs have become popular in recent years as a result of larger bathrooms being constructed. Freestanding bathtubs may be made from various materials such as stone resin, cast stone, acrylic, cast iron, fiberglass, porcelain, copper, and cement.

Soft tubs are made from soft plastic or foam with a protective non slip coating. While soft tubs have been available since the 1970s, by the 1990s they were being sold by major manufacturers.

Inflatable bathtub is a specialized bathtub that is portable, and can be used both indoors and outdoors. They are especially well suited for bathrooms that have shower, but don't have built in bathtubs. They are also inexpensive and save room space. with some models even having cup holders installed in them. Inflatable bathtubs usually consist of many smaller inflatable parts, together forming a bathtub.
