The bathroom is a room of water, you do not learn anything ... So do not connect any device anywhere. It is for this reason that the NF C 15-100 Standard requires four zones or safety volumes.

The bathroom is divided into four safety volumes:
Volume 0 is the bath or shower: any appliance are tolerated (however, there are spas or complete shower cubicles with integrated spotlights).
The volume 1 corresponds to an area of 2.25 m from the bottom of the tub or shower pan. Above each of these health, we only accept light fixtures and switches Safety Extra Low voltage 12 V, NF certified and protected against water protection (IP X 4 minimum).
Volume 2 vade 3 meters from the bottom of the tub or shower pan 60cm around. In this area, the electric lights or heaters shall be class II, carry the NF mark and be protected against rain (IPX 3). Only sockets are admitted "razors" equipped with isolating transformer.
Volume 3 is the entire area of the bathroom that is distant from over 60 cm are permitted volume of 0. electrical equipment and electrical equipment class I, plugs the type 2P + and boxes connection. They must bear the NF mark and be protected against vertically falling drops of water (or IPX 1).
The protection class (IP) is an international standard of the International Electrotechnical Commission on the seal. This index ranks the level of protection offered by a material to solids and liquid intrusion. The index format, given by IEC 60529 is IP 55 where the letters are 55 two-digit and / or letter. The numbers indicate conformity with the conditions summarized in the tables below. When no criteria are met, the figure can be replaced with the letter X.
1st digit index (ten) = Protection against dust 2nd digit (unit) = Protection against water
0 No protection. No protection.
1 Protected against solid objects greater than 50 mm. Protected against vertically falling drops of water.
2 Protected against solid objects greater than 12.5 mm. Protected against water drops falling up to 15 ° from vertical.
3 Protected against solid objects greater than 2.5 mm. Protected against spraying water up to 60 ° from vertical.
4 Protected against solid objects greater than 1 mm. Protected against water spray from all directions.
5 Protected against dust. Protected against water jets from all directions to the lance (12.5 mm nozzle, 12.5 l / min).
6 Totally protected against dust. Protected against water jets from all directions to the lance (22.5mm nozzle, 100 l / min).
7 - Protected against the effects of immersion (up to 1 m).
The ingress of water in harmful quantity is not possible when the equipment is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).
8 - submersible equipment under specified conditions (prolonged immersion) beyond 1 m for 30 minutes
Normally, this means that the equipment is sealed. However, with certain types of equipment, it can mean that water can enter but only on condition that it does not produce harmful effects. Protection against flooding.
9 - submersible equipment under specified conditions (prolonged immersion) beyond 1m and protection against high pressure cleaning.
Normally, this means that the equipment is sealed and it can withstand a high water pressure.
9K - submersible equipment under specified conditions (prolonged immersion) beyond 1m and protection against high pressure cleaning.
Normally, this means that the equipment is sealed and it can withstand a high water pressure. Standard Food / Kitchens / etc ...
