We have a two story house with a basement, so there are a lot of steps. My wife did have the foresight (and she gets ALL of the credit) to design the floorplan so that all of the living space is on one floor. We don't have to use the steps very much.
We have a frame very similar to this one on one toilet. They are available from Amazon. Just enter toilet frame, and search. The toilet in the master bathroom has handriails installed in the wall. They are definitely a help. As you know some days are worse than others with gimpy knees. Hope this helps.
