it is essential to contact the galvanized to discuss with them the problem (also depends on the size of their galvanizing tanks).
so "nose" I don't see it impossible, maybe you will have to give a minimum of "pendence" to the horizontal traits to avoid the accumulation of zinc.
Another problem is the temperature of the bathroom, very high, which could deform the artifact (although in such an application I do not see it so problematic).
