Whether or not bees repair comb to something useful depends mostly on what
sort of foundation you used.
 
In my experience, only the plastic foundations (e.g.; Pierco) will be redrawn
into "good as new" combs.
 
Duragilt will not in general be rebuilt, or worse, the bees will build burr
comb over it.
 
Wax foundation may get rebuilt, but will generally be rebuilt as drone comb.
 
I applaud the idea of setting the supers in a bathtub as an example of a big
disaster averted by forethought.   Honey in a bathtub is a lot easier to
clean up than honey on the bathroom floor.
 
When I give talks on handling honey, wax, and/or sugar syrup, I always stress
the principle of disaster control by containment.   Stuff will spill.   Make
sure that when it does, it will go into something that is easy to clean and
will keep the mess from spreading.
