Install a bathroom exhaust fan, go to the hardware store and ask them will give it to you, the bath bomb can be installed in the back, and the power cord can be reserved in the ceiling, and then consider increasing it if you feel that it is not warm enough in winter.
The bathroom is too closed, there is no place for ventilation, the "vacuum resistance" of the exhaust fan is very large, and the air is basically not pumped, resulting in a large amount of fan blade shaking, which is a normal phenomenon, and it will be discharged only when the door is opened for ventilation.
If you are using an aluminum gusset and have been informed that there are exhaust fans and ceiling lights for the installation, then you are reserving the skeleton for installation.
Probably not, the heating exhaust fan in the bathroom is on the bath bomb, and the ventilation exhaust fan should be installed on the wall to pump the air out of the bathroom.
The hose of the normal exhaust fan is 100, press this to leave it.
