A bathtub also simply called a bathtub or bathtub, is a container of water in which a person or animal can bathe.Most modern bathtubs are made of thermoformed acrylic, enamelled steel or cast iron or fiberglass reinforced polyester.The bathtub is placed in the bathroom, either as a freestanding fixture or in combination with a shower.Modern bathtubs have an overflow and a waste drain that may have a faucet attached to it.They are usually built-in, but may also be freestanding or sometimes recessed. Almost all tubs used to be roughly rectangular before acrylic thermoforming allowed for other shapes.Tubs are usually white, but many other colors can also be found.

Two main styles are common: 

A Western-style bathtub in which the bather lies.These tubs are usually shallow and long.Oriental style bathtub where the bather can sit up. These are called furo in Japan and are usually short and deep.

Types

Clawfoot tub:

Considered a luxury in the late 19th century, claw-foot bathtubs were originally made of cast iron and lined with porcelain.Modern technology has led to a drop in price for claw foot bathtubs, which may now be made of fiberglass, acrylic, or other modern materials. Clawfoot tubs generally require more water than standard tubs because they are usually larger.While authentic antique clawfoot tubs are still considered collectibles, remodelers and new home builders opt for new imitation clawfoot tubs, and much like Western-style tubs clawfoot tubs can also include a variety of shower head options.

Clawfoot bathtubs come in four main styles:

• A classic roll-top bathtub, also known as a roll-top or flat-top bathtub, as shown in the picture at the top of this page.

• Slipper Tub-One end is raised and angled to create a more comfortable lying position.

• Double slipper tub-raised and sloped at both ends.

• Double-Ended Bathtub-The tub is rounded at both ends, as opposed to the classic roll-top tub, which has a rounded end and a fairly flat end.

Pedestal tubs:

Pedestal tub rests on a pedestal, many called it Art Deco.Evidence of pedestal baths dates back to Crete around 1000 BC.

Baby bathtub:

Baby bathtubs are used to bathe babies, especially those who are not yet able to sit up on their own.These can be small free-standing tubs filled with water from another water source, or a baby-supporting unit placed in a standard tub.Many are designed to allow the baby to recline while keeping the head out of the water.

Hot tub:

Hot tubs are common pools of warm water used for relaxation and sometimes therapy.Hot tubs became popular in America during the early hippie era (1967-1980), appearing in movies and music.

Whirlpool tubs:

Whirlpool bathtubs first became popular in the United States in the 1960s and 70s.A spa bath or hot tub is also known as a "jacuzzi" as the term became common after plumbing parts manufacturer Jacuzzi introduced the "Spa Whirlpool" in 1968. Air bubbles can be introduced into the nozzle via the exhaust venturi pump.

Freestanding bathtub:

Freestanding bathtubs have become popular in recent years due to the construction of larger bathrooms.Freestanding bathtubs can be made from a variety of materials such as resin stone, cast stone, acrylic, cast iron, fiberglass, porcelain, copper, and cement.

Soft tub:

Soft tubs are made of soft plastic or foam with a non-slip protective coating.While soft tubs have been available since the 1970s by the 1990s they were being sold by major manufacturers.These bathtubs are often marketed to children and the elderly to prevent falls and injuries.
