Accessible bathtubs are bathtubs that can be used by people with limited mobility or the disabled. A bathtub can be made accessible for some people by the addition of grab bars or hand grips, or through the use of lifts that lower and raise the bather in the water. Other bathtubs have been specially designed for accessibility. These may include walk-in bathtubs, tubs with built-in transfer benches, or, more recently, tubs with raised beds and sliding doors to allow for a seated transfer.
