Why Are Bathroom Light Switches on the Outside? Bathroom light switches are on the outside because it reduces the risk of electrocution, provide safety and protection, and are easy to reach.

Why are light switches on the outside of the bathroom?
Many interior designers and electricians recommend having them outside the bathroom to avoid any accidental situation for you and your family members.
Risk of electrocution
This place has a high moisture and humidity level because of the frequent water use in the shower, bathtub, and vanity areas.
Water and electricity are a deadly combination that can damage the bulbs, light fixtures, and other things connected to this circuit.
Moreover, it can harm you; even a big short circuit can cause death if you are in contact with the switchboard.
Water has many minerals and salts that are good conductors of electricity, and the wires in electric circuits are made of metal which is also an excellent conductor of electricity.
Water splashes or moisture can get into the switches, and the risk of electrocution increases if they are near the shower area and bathtub.
Severe electrocution can cause serious damage to you and your property if the condensation from your shower accumulates around the switchboards. In addition, there is a risk that you touch it accidentally without knowing about it.
Safety and protection
They are installed outside the bathroom for the safety and protection of the users. You can touch the switches with wet hands and a moist body after taking a shower or washing your hands.
This will increase the risk of getting an electric shock because water attracts electricity. The human body has a resistance of several mega ohms to electricity when it is dry.
Wet skin reduces the body’s resistance to 990-1000 ohms and allows electric energy to break down through your body.
It can reduce the chances of touching them with wet hands or body as you turn the light on or off.

These switchboards are easy to reach for you, your children, and guests.
However, the guests or visitors can fumble around or find it difficult to search the switchboard in the dark.

Standard building code
Many building codes restrict installing the light switches inside the bathroom or neat the bathtub and shower areas to avoid any accidental situation.
Standard building codes in the UK restrict the electricians from placing them inside and at a safe distance from the user, such as 2-3 feet away.
They mostly use long cords for switching the light on and off, keeping the wet hands and body away from dangerous spots.
Requirements in America are not restricted to the outside installation of light boards as they mostly use watertight boards covered with a waterproof shield to avoid any electrocution and at a safe distance from the bathtub and shower area.
In addition, they use AFCI-protected outlets that reduce the risk of sparking and are safe to install on the inside.
It is hygienic to have them outside because you might turn off the light of your toilet with germs on your hands when its switch is inside this place.
The person who enters after you can get the bacteria and germs from the switch if you touch it with dirty hands.
You can easily clean the walls, windows, and other things with wet clothes and cleaners without having the risk of water splashes and moisture in the electric boards.
You cannot clean the stains with wet sponges and sprays if the light switches are around the vanity and sink because this can cause moisture to enter the boards, and a short circuit can happen.
