Walk-in bathtubs are also referred to as safety tubes due to the fact that users need not raise their legs to climb into them. They can just enter the tub and due to the watertight doors, there is no danger of any water leaking out once you are in the tub. They come with all the facilities associated with conventional bathtubs including Jacuzzi-style water jets.
Walk-in bathtubs were conceived to make things easier for the old, infirm as well as physically challenged individuals. They are usually taller as well as narrower and this makes them an easy fit into smaller spaces.
