After using the toilet some elderly or disabled people find it difficult to us the conventional methods of cleansing because of their inability to move freely. 
In such situations, bidets provide a more hygienic alternative to toilet paper as they are not only easier to use but also do not require much movement. 

A bidet gently sprays warm water towards the required area of the body, cleansing the area and reducing the risk of infection. 

Bidets have many advantages. Because it is a hands-free device, it may not necessary for a carer to present. This will allow a greater feeling of confidence, and dignity

Shower toilets
An automatic shower toilet combines the functions of loo and bidet in one unit, enabling many disabled people to use the toilet unaided. 
Purpose-built units, and various add-on "bidet toilet seats" which can be fitted to an existing toilet are available.
