Do most recommend a 20A GFCI outlet in a bathroom as a result of the potential wattage used by hair dryers and other small electrical appliances that use a great deal of watts?
There is no need for a 20 amp slot GFI in a bathroom. You will not find appliances in a residential setting that need the T-slot. Even a 15 amp slot GFI is rated for 20 amp thru-put.
