Piccadilly Circus has toilets, but again outside the barrier. I
suppose they might have more to do with the local authority than TFL

riverbank. As I recall they were once voted the best in London. Though
judging by the smell when I passed by the other week, I would think
that accolade is no longer theirs.

Westminster also has some within the station (but outside the barriers)
under Parliament Street (head for the exit next to the Treasury).
