Keys to the successful design and construction of an accessible bathroom:
Many bathtubs now come with grab bars molded into them.
For safety sake the bathtub chosen should have a non-slip, flat bottom. If grab bars are not part of the bathtub they should be installed on the wall.
The bathtub can present accessibility problems even for those without any disabilities. Falling while getting in or out of a bathtub is one of the most common accidents in homes. Both vertical and horizontal grab bars should be installed, as shown in Figure 33.

The intent of the grab bars in the bathtub space is to aid in getting in and out of the tub. For that reason, a grab bar should be installed horizontally at a height of 7 to 11 inches above the bathtub rim, running the full length of the tub.
A second horizontal grab bar should be installed the width of the tub where the water control valves are located.
A third vertical grab bar positioned at the entry point of the bathtub allows the individual to grab something while stepping over the side of the bathtub.
If grab bars are pre-installed in the bathtub you have chosen, ensure that they are capable of taking the pull weight of an adult.
If you are providing for accessibility to the bathtub for an individual that cannot easily step over the sidewall of the bathtub, there are numerous styles of bathtub lifts that can be placed in most bathtubs, as shown in Figure 34.

Having a portable or Folding bath seat available, as shown in Figure 35, for placement in the bathtub, should also be considered.
Walk-in bathtubs, as shown in Figure 36, are a relatively new product. They provide easy access to the bathtub by providing a watertight, lever handled, door on one of the sides.

These walk-in bathtubs can be purchased as basic bathtubs or can be equipped with all of the extra features such as water jets. All models have integral seating. In fact these walk-in bathtubs are being installed in high-end homes, as shown in Figures 37,38 and 39, they are no longer considered only a fixture for the elderly or disabled.

Walk-in bathtubs are however, the perfect answer for individuals with mobility problems who are still capable of bathing on their own.
It is still important to consider the installation of grab bars in appropriate positions to aid the individual in standing and gaining access to the walk-in bathtub, if they do have any balance problems.
