First, it is excellent that you are willing to make changes for a disabled family member – too many of us disregard this. One feature you should focus on, though, is Worthing disabled bathrooms. Your home will become much easier to use, and your grandfather will likely feel more control and more independence by being able to use the toilet themselves.
These little features can be easily installed by professionals. You could use one of the many local companies, such as Plumbit Ltd, to resolve the problem quickly and easily. They can help you set up, plan, and manage your disability bathroom.
This is highly recommended as a feature, and your grandfather will find life much easier. It is one small step to ensuring he retains his independence and free will.
