I do something similar - except I use a couple of big plastic tubs from Bunnings, each of which is big enough to take a fermenter sideways.
On brewday, EVERYTHING lives under about 10 litres of iodophor solution (1 capful) in one of the plastic tubs - thermometers, spoons, hydrometers, airlocks, o-rings, tubing, spigots etc. This means no little sticky puddles around the place, nothing gets lost (its always in the tub), and everything is clean and sanitary at all times (including my hands). The other tub just has warm water in it and is used to give sticky things a quick dunk before they go back in the iodophor.
During the boil, the fermenters go into the iodophor and get rolled around from time to time. I figure this way everything (including the tap sockets, neck threads etc) gets a good soak.
When I'm finished both tubs are emptied and dried, one tub nests inside the other one and a lot of my brewing stuff goes inside with a single lid to keep the crap out.
It sounds more complicated than it is :beer:
