GC's architect calls for bathroom exhaust fan /w light in shower/tub area in his plans. I told the architect that the installation is not per code, due to the fact that the unit is not marked "Wet Locations". I refused to rough-in/ wire this unit, but cannot find the correct section of the code to site. There is no rubber gasket or other protections. Can anyone assist me in finding something here. I don't mind putting this unit outside the confines of the shower/tub area. Thank you.
