I have enough spare tubs for one rack, enough extra water bowls for everyone and then some, and a couple of extra hides.
When I'm doing cleaning I like to have a clean tub to just place the snake right into. So I get a clean tub all ready, place the snake in that and then put him and the clean tub back into the rack. I do this for a whole rack and then I go and clean the tubs. This way I can clean them and let them dry with out having to worry about doing it quickly to get them back in.
Same thing with the water bowls. I just take out the old one and put in a new clean one once a week. Then I can go clean the old ones. I only keep a couple of extra hides to clean if they get soiled. I have a couple that insist on pooping all over their hide; but most poop away from it so I don't have to clean those very often.
But as for thermostats and thermometers, I don't keep extras of those.
