[Avodah] Showering during shiva

[Zev Sero]

Does anyone know whether there's a general consensus among contemporary 
American rabbonim about showering during shiva, for the average American 
who is used to showering every day, or at the very least every other 
day?  Surely we are not less astheneses in this regard than Rabbon 
Gamliel.  During the 9 days most if not all American rabbonim seem to 
pasken this way, but do they do the same for shiva?
