Elderly people as well as the disabled get a sense of security when they are able to use walk in bathtubs. These tubs are designed with many special features that ensure the safety and security of the user. The basic features of a bath tub that one must look for are as follows.

The design should be such that the user walks into the tub and does not have to climb over its side.
The doors of the walk in bathtub are configured in such a way that they lock and seal to prevent any leakage of water on to the bathroom floor. There is a choice of doors which open either to the left or right as also doors that open outwards or inwards.
The safety seat in a walk in tub is such that it is built in and provides a seamless design. It is convenient especially for a person who cannot stand and bathe.
The non skid or a non slip bathtub floor and safety handles or railings on the side of the tub will not only enable the user to enter and leave the tub easily, but also reduce the risk of injury due to a fall
The walk in bath tub has soothing interiors and the controls are placed in such a way that the user has easy access to them. Such a tub is made of fiber glass and acrylic which makes it easy to clean.
Quick fill and quick drainage are other basic features of the tub.

Besides the above mentioned basic features, some walk in tubs also have some non basic features like:

Optional Showers: These showers can either be fixed to the faucet as a hand held shower or can be free standing showers.
Jacuzzi Jets: Walk in bathtubs with Jacuzzi jets which are installed inside make bathing a more enjoyable and therapeutic experience.
Spa: For those who enjoy spas, and aromatherapy massaging jets and spa like treatments can be fitted into the tub.
Hydrotherapy: Some walk in tubs also boast of features like hydrotherapy jets, and whirlpool bath options.
