A decent sized walk in bath, with a normal height seat, and a Jaccuzi function, but not so narrow that your hips touch each side of it, and your knees are pressed right up to the tap end! Oh, and a nice wide door that you can walk forward into and not have to squeeze sideways! They make some lovely ones for the American market, but for some strange reason they are not available in the Uk!
Swivel car seats that allow you to sit down straight into the seat, without having to struggle to sit and pull yourself in and straighten up sideways afterwards. I say watching people arriving and departing at our Local Covid vaccination centre yesterday, and felt really sorry for the elderly people struggling to get in and out of a car and straighten up into the seat sideways themselves, a swivel seat would be so much simpler.
