You have partly been given the correct advice already, but I just wanted to clarify matters a little.
I agree that you need to have your home and your needs assessed by the Community Occupational Therapist (OT). They will be part of a team based within your local authority. You can ask your GP to rather you, or in most instances you can make direct contact with them yourself.
There is a host of different equipment available and part of the role of the OT is to match your needs to what is available and appropriate to you in your circumstances. In most instances small items (like basic bath aids, grad rails, etc) can be supplied for free from the local authorities 'minor adaptation budget'. There are regional differences to these budgets, see:
Larger adaptations, such as stairlifts can be funded via a Disabled Facilities Grant (DFG), these are means-tested for adults:
If you decide that you want to explore further about the sort of aids and adaptations that can be useful to disabled people there is a wealth of further information in the Equipment Section of the Scope website:
Another website that can be helpful for exploring equipment is AskSARA, it is interactive and can provide information tailored to your needs:
Hope this helps,
