I agree with Hazel, bed and couch -peeing is a really common problem. Some people have had success with putting a plastic shower curtain under a blanket as the “top” layer on the bed, as the plastic blocks some of the smell, so the bun is less likely to pee, and then your bedding is at least protected if they do. But I don’t think that would be very comfortable for sleeping, so you might need to block access unfortunately.
As Hazel said, it’s not so much a dominance issue as territorial marking, I’m guessing triggered by the rearranging and cleaning of everything. Restricting her space temporarily and then gradually increasing it also might help.
Glad you got the ringworm under control, it is such a pain! One of the foster moms at the rescue I volunteer at ended up covered in it because her foster babies got it.
