Eastern style bathtubs in which the bather sits up modern bathtubs have overflow and waste drains and may have taps mounted on them. They can be built in or freestanding lines or sometimes sunken lines. Until recently, most bathtubs ideas were roughly rectangular in shape, but with the advent of acrylic thermo-formed baths, more shapes are available. Bathtubs are often white or black, although many other colors can be found.
