Bathtubs are large containers with a tub shape that hold water. Applications for bathtubs include bathing and cleaning of persons and animals, medical therapy, recreation, and relaxation. Bathtubs vary in size and color based on décor and intended use. They mount on the floor or another flat platform either directly or free standing with feet for support. 

Types of Bathtubs

A standard bathtub is found in many residential homes. It is usually large enough to accommodate one adult person, and comes equipped with plumbing fixtures to add hot or cold water to the tub as well as a closable drain to keep the water in the tub. 

A whirlpool tub is similar to a standard bathtub in size and function but provides water jets in the tub to provide a therapeutic or relaxation function while bathing. 

A hot tub is a large bathtub that is not intended for bathing and cleaning purposes. A hot tub is sized to fit two or more adults and can included integrated seats within the tub. Hot tubs will also have integrated pumps and heaters to circulate and heat the water in the tub. 

Materials

Bathtubs are commonly made of porcelain or composite materials such as acrylic or fiberglass, but may also be constructed using cast iron, copper, marble, or ceramic tile.

Configurations

• Clawfoot—The bathtub has four curved feet that the tub will rest on.
• Corner—The bathtub is mounted in the corner of a room with a wall on two sides of the tub.
• Alcove—The tub is a drop-in insert for a small alcove built into one wall of a room. The tub will have a wall on three sides.
• Walk-in—The bathtub has a door for entry. This configuration is accessible, safe, and is often equiped with a built-in chair and textured floor.
