It should tell you the max wattage inside the fixture.

I am having an ICAT recessed 6" can put into my bath/shower area. It will have a shower trim over that. What is the largest Par30 watt bulb a person can put in that type of enclosure? Thanks.

Usually it's 60 watts and it would be a regular bulb, not a flood light.
As said, it should be stated on the can. just look for the trim your using as that's what will dictate the bulb size and type.

Keep in mind most of those can lights these days have a thermo-disconnect and will shut off if a too large bulb is used.
