I would like to know any pros or cons to installing and using a ceiling infrared heat exhaust fan in a bathroom to take the chill off when stepping out of the tub.

Infrared heat lamps provide spot heating. They heat up fast, but but some people may find the hot, direct beam harsh.
It's important that your exhaust fan have adequate capacity. The Home Ventilating Institute (HVI) recommends that the fan be capable of exchanging the air at least eight times every hour. To determine the required fan capacity in cubic feet per minute (CFM) for a bathroom with an 8-foot ceiling, multiply the room's length and width in feet by 1.1. For example, if your bathroom is 6 by 9 feet, you would calculate the required fan capacity as follows:
6 x 9 x 1.1 = 59.4 CFM
Rounding off, you would need fan capacity of at least 60 CFM. If your fan must exhaust through a long duct or several elbows, you'll need greater capacity to overcome the increased resistance. Follow the manufacturer's recommendations.
Most fans have a noise rating measured in sones: the lower the number, the quieter the fan.
