Forced ventilation in the bathroom
The so-called natural ventilation, equipped in the bathroom combined with the toilet, is usually a regular opening located in the upper part of the wall and connected to a common ventilation riser.
In a separate bathroom, a ventilation hatch may be absent due to the fact that its space is partially combined with a toilet (due to the incomplete partition between them).
Surveys of ventilation systems of this type, conducted by users as a private initiative, allow us to draw the following conclusions:
- Ventilation through a niche in the wall is absolutely not effective.
- The air duct of the ventilation duct in the toilet does not provide the required thrust required for the normal functioning of the system.
- The dimensions of the hatch connecting the duct with the riser ventilation shaft, most often do not correspond to the norm.
The results of the survey results convincingly prove that the organization of forced air circulation in the bathroom is vital.
Selection of system elements
In our review, we will try to acquaint you with how to make forced ventilation, taking into account the drainage channels that already exist 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.
For its arrangement the following materials and equipment will be required:
- plastic pipe, selectable by the size of the mounting hole;
- electric fan of suitable size and power;
- decorative grille made of plastic.
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 an unformed ventilation hatch it is possible to prepare a normal bypass channel, laid directly to the riser.
We remind you that before installing the pipe it will be necessary to remove from the mine the remnants of debris accumulated in it.
Installation procedure
To organize forced air circulation in the bathroom, an electric fan is required, which is placed directly in the ventilation duct and ensures the creation of the necessary traction in it.
After cleaning the canal 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 in such a way 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 channel design, 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 in the pipe billet with a smaller diameter or, by increasing the landing size of the fan due to the use of 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, this mounting is quite enough for reliable fixation of equipment in the ventilation duct. From above, the front panel of the device can be closed with a decorative grille attached with the same liquid nails.
The electrical connection of the ventilation equipment to the existing residential network should be made in accordance with the instructions for its connection. 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.
In the final part of the narrative, I would like to remind you that in order to minimize labor costs, the installation of exhaust ventilation is usually performed simultaneously with the repair of the room. Such a combination will save you from a number of inconveniences associated with the repair work in the auxiliary premises.
