I have found Concrete Mixing tubs to be super useful for anything soil/repotting related work.

I have 3 three sizes that nest and use them for grading soils when sifting, capturing repot soil to sift, I also repot directly in them on a work bench to catch soil. All in all they are great "work containment" containers which can also be great for immersive watering during the height of summer.
bonus: I usually use heating beds after repots and towards the end of repotting season I can put a germination mat in them, dump some pumice on and expand my healing in area without too much fuss.
