Location of hair dryer in bathroom and hotel
The purchase and installation of an electric hair dryer, particularly in a place open to the public, is not without risk and must be done by a knowledgeable professional.
Class II
Only class II hair dryers with double electrical insulation may be installed in bathrooms. These hair dryers are identifiable by the standard symbol.
Hair dryer IP rating
The IP index consists of two numbers:
- the first number represents the level of protection of the hair dryer against solid bodies (e.g. IP 2 1);
- The second number represents the level of protection of the hair dryer against liquid elements (eg IP2 1).
For installation in volume 2:
- IPX 3 minimum (flexible device)
For installation in volume 3:
- IPX 1 minimum (extension cord, hair dryer must not penetrate volume 2)
The 4 bathroom volumes are defined by the installation rules of the NFC 15.100 standard.
Technical characteristics of the electric hair dryer
Hair dryer flow rate and power
These parameters determine the speed of the hair dryer drying. Higher numbers increase the speed of the hair dryer drying.
ON/OFF switch on the hair dryer holder
It allows you to cut off the general power supply to the hair dryer.
This system is required by safety standards in some countries.
Differential switch on hair dryer
It eliminates the risk of electrocution even in humid environments by instantly switching off the electric hair dryer.
The differential switch has been mandatory in France since 1991 in all new or renovated electrical installations. In this case, the differential switch on the hair dryer is unnecessary, as the electric hair dryer is already protected.
Otherwise, a differential switch is essential.
Shaver socket on hair dryer
This option offered on the hair dryer wall mount avoids an additional specific electrical outlet.
The shaver socket is limited in power to 20 W for the exclusive use of electric shavers or phone chargers.
It accepts all types of cards:
- with transformer: 230 V and 115 V output;
- without transformer: 230 V output only.
Left/right positioning of the hair dryer gun
This feature allows for easier use and installation of the electric hair dryer in perfect harmony with the layout of the bathroom.
Hand-held operation
This safety system automatically cuts off the power to the hair dryer when it is no longer in use.
How to read the IP protection rating?
First digit: protection against solid objects
| IP0X | no protection |
| IP1X | protected against solid bodies >50 mm (e.g. hand contact) |
| IP2X | protected against solid bodies >12.5 mm (e.g. finger) |
| IP3X | protected against solid bodies >2.5 mm (e.g. tools, screws) |
| IP4X | protected against solid bodies >1 mm (e.g. small tools, wires) |
| IP5X | protected against dust (no harmful deposits) |
| IP6X | completely protected against dust |
Second digit: protection against liquid bodies
| IPX0 | no protection |
| IPX1 | protected against vertical drops of water |
| IPX2 | protected against water drops up to 15° from the vertical |
| IPX3 | protected against water drops up to 60° from the vertical |
| IPX4 | protected against projections from all directions |
| IPX5 | protected against water jets from all directions (water lance) |
| IPX6 | fully protected against projections (similar to sea waves) |
| IPX7 | protected against the effects of immersion |
