Code Requirement for Bathroom Vent Location | Bathroom Exhaust

Bathroom Vent Location | Bathroom Exhaust

Well, there’s no specific building code requirement for the bathroom vent location / exhaust fan installation. You can have it almost anywhere on the ceiling or wall (floors are forbidden due to possibility of vent flooding). The one you see on the picture is slightly above the floor level (it’s actually just a register, fan motor installed in the attic above), and I personally guarantee that in this location works like a charm (this bathroom has one more above the shower stall).

Bathroom GFCI Receptacles and Electrical Components

Bathroom GFCI receptacle protection is required by the NEC (National Electrical Code), and of course by the common sense – why would you risk getting electrocuted if you can secure your safety by installing GFCI outlet.
Since some bathrooms are currently equipped with many electrical current hungry devices, power supply requirements had to be slightly adjusted. We used to have a bathroom sharing an electrical circuit with exterior outlets, the kitchen, and a garage – not anymore.
Of course, the minimum requirement listed below is not going to work if you add a steam shower, heated electric floor, hydro-spa heater, several light […]
