Can I use a small ladder with rubber feet in a CI bathtub?

The tub floor is protected with cardboard.

While it's better not to, sometimes you have to. It should be ok.

If you have half inch ply, cutting it to fit the tub is an option. Any ladder feet may quickly rip through the cardboard. I've wrapped the feet with tape also for temp work.
