The problem with a cellar is drainage. Prints need to be fixed, then
(ideally) washed for a LONG time under running water.

I used to put them in the bath and run water over them, I cut a bit of pipe to insert in the plug hole, drilled a few holes up the side so the water would go down the plug hole. I used some old net crutains on a wooden frame across the bath to dry the prints.

Unless you can get
a decent sized bath tub in there to collect the run-off, using the cellar
could be problematical.

dirt might be a problem in a cellar.
