Happily I have a backup litter box chest. Back when I had a very old cat, I needed one in the living room and one in the sewing room. PetCo had a plastic (easy to clean) collapsible one at the time and it was perfect. When I didn't need it any longer for litter, I used it in the closet to store blankets.
Since I cleaned out that same closet not long ago, I had places for all the blankets and could just recommission the chest for litter! I also remembered to grab an old shower curtain liner to line it so that it will be easier to make ready for blankets again. I found a picture of what I'm talking about - cat not mine :)
It will be replaced by the new one from Etsy soon. This is what is coming - mine will be painted white.
Anyway, now the deed is done. So yeah!
