Forced ventilation in the bathroom - install exhaust fan in the bathroom

The so-called natural ventilation, equipped in the bathroom combined with the toilet, is usually a regular hole located in the upper part of the wall and connected to a common vent pipe.

In a separate bathroom, the ventilating hatch may be completely absent due to the fact that its space is partially combined with a toilet (due to the incomplete partition between them).

In the separate bathroom

Examinations of ventilation systems of this type, carried out by users in the order of private initiative, allow to draw the following conclusions:

1. Ventilation of the bathroom through a niche in the wall is absolutely not effective.
2. The air duct of the ventilation duct in the toilet does not provide the required thrust necessary for the normal functioning of the system.
3. The dimensions of the hatch connecting the air duct to the riser ventilation shaft, most often do not correspond to the norm.

The results of the survey convincingly prove that the organization of forced circulation air in the bathroom is vital.

Selection of system elements

In the bathroom

In our review we will try to acquaint you with how to make forced ventilation, taking into account the drainage channels already available in the bathroom (toilet). But, first of all, it will be necessary to decide on the basis of which components the future system will be constructed.

The following materials and equipment will be required for its construction:

• plastic pipe, selectable by the size of the mounting hole;
• electric fan of a suitable size and power;
• plastic decorative grille.

The choice of the shape of the ventilation duct is determined by the shape of the exhaust fan. The plastic box itself is necessary so that in place of the unformed ventilation hatch it is possible to prepare a normal drainage channel, laid directly to the riser.

We remind you that before installing the pipe it will be necessary to remove the remains of construction debris accumulated in it from the mine.

Installation Procedure

Fan Installation

To organize forced air circulation in the bathroom the room will require an electric fan, which is placed directly in the ventilation duct and ensures the creation of the necessary thrust in it.

After cleaning the duct from debris and dirt, a plastic pipe is laid into it, the installation dimensions of which are selected in accordance with the dimensions and length of the ventilation hatch. In this case, the diameter of the pipe is usually taken so that it is installed in the channel with a small amount of tightness, ensuring its rigid fixation in the aperture.

At the end of the design of the channel, it will be possible to start fixing the fan casing, which (if possible) should correspond to the diameter of the pipe already installed. In case of mismatch of the installation dimensions, it will be possible to adjust them by placing billets with a smaller diameter in the pipe or, by increasing the size of the fan, by using additional gaskets.

Immediately before installing the fan, a strong adhesive is applied to the wall section around the pipe (for example, liquid nails). Since modern fans are made of lightweight materials - such an attachment is quite enough for reliable fixation of equipment in the ventilation duct. From above, the front panel of the device can be covered with a decorative grille attached with the same liquid nails.

Plastic pipe

The electrical connection of the ventilation equipment to the existing residential network should be made in accordance with with instructions for connecting it. In this case, it is necessary to comply with the requirements for the safe installation and operation of electrical equipment in rooms with a high level of humidity.

Connection

In the final part of the narrative I would like to remind you that in order to minimizing labor costs installation of exhaust ventilation is usually performed simultaneously with the repair of the premises. Such a combination will save you from a number of inconveniences associated with the repair work in the auxiliary premises.
