DIY ventilation installation in the bathroom

Do-it-yourself ventilation in the bathroom is usually an exhaust fan. It is mounted in the ventilation duct. The principle of operation of this ventilation scheme in the bathroom: a fan draws air from the bathroom into the general ventilation system of the house. The air in the room is discharged, so fresh air is drawn in from it from other rooms.

To check whether forced ventilation is needed in the bathroom, you should check for natural draft:

  • Take a small piece of tissue paper;
  • Open the bathroom door and any window;
  • Bring the sheet to the exhaust grill. If the paper holds and does not fall, the draft is normal. Otherwise, it is necessary to equip the forced ventilation in the bathroom.

How to choose a fan for the bathroom

The basis of the ventilation scheme in the bathroom is an exhaust fan. There are many modifications on sale, which one to choose?

  • The hum from the fan should be no more than 35 decibels;
  • Fan power should provide five to eight times air exchange per hour.

By type of installation, all fans are divided into:

  • channel (installed directly in the ventilation duct);
  • radial (at the entrance to the ventilation duct). They are most often used for arranging ventilation in the bathroom.

Before you make ventilation in the bathroom, you do not need to mount exhaust ducts. The fan is installed directly in the outlet of the exhaust duct. However, if the shaft does not pass near the bath, you will have to pull the duct pipe. If the mine outlet is located in a toilet located through the wall, you can make a ventilation hole in this wall, cover it with a grill and install a fan in the toilet shaft.
