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.
[3] Many accessible bathtubs are available with hydrotherapy or whirlpool features, internal grab bars, anti-slip floors and seats, and handheld showerheads that, in some cases, can also be wall mounted to enable a person to take a standing shower.
[citation needed] However, the advantage is that an inward opening door is "self-sealing" due to the pressure of the water inside the bath assisting in maintaining a water-tight seal.
This type of walk-in bathtub can be helpful to wheelchair users and to others with mobility impairments.
There are also smaller walk-in tubs that offer front and side entry for a less-than-standard space.
