Our toilet paper roll upstairs in the main bathroom is behind a trash
can which is wedged between the toilet and the vanity. She can't get
around it and she can't get around the toilet - or doesn't try upstairs.
She hasn't taken an interest in the toilet paper yet in the smaller
bathroom (touch wood...)

I used to pet-sit for some relatives and one of their
cats shredded toilet paper and paper towels. Both had to
be hidden in a cabinet and the cabinet "locked" because
Ginger also liked to open things. Frequently I'd come in
after work and there would be clothing in the hallway
where she'd opened a drawer/closet/hamper and fished it
out and carried it around the house. Big things, too,
like once she pulled a bath towel off the rod and dragged
it downstairs. One day I forgot to lock the kitchen
cabinet where the paper towels were kept and came home
to a huge mess in three different rooms. She unrolled
the whole roll, apparently dragging it from room to room
(almost like kids "TP'ing" a house), then shredded a
bunch of it, and the tube. At least it kept her out of
the underwear drawer that day. :)

She grew out of the habit. Maybe yours will, too.

It has been said in this group that cats do not like citru small and for
that reason it makes a good cat repelant.  Perhaps a small plug-in citrus
deoderizer would discourage the cat from going into the bath room.

Citrus scented toilet paper might have the same or maybe better effect.
