In this article you’ll learn:
- why bathroom sockets are subject to special installation rules and how humidity affects installation safety,
- which electrical safety zones apply in a bathroom and in which of them sockets may be installed,
- at what height sockets and switches should be installed so they are comfortable to use and compliant,
- where best to plan the socket for a washing machine to avoid water contact and future problems,
- which sockets are suitable for bathrooms, including which IP rating is essential,
- which mistakes to avoid so the bathroom electrical installation stays safe for years.
Why do bathroom sockets require special rules?
Water and electricity are a combination that requires control. In a bathroom, the risk of the electrical installation coming into contact with moisture is much higher than in other rooms. That’s why regulations define exactly where and which types of sockets may be installed.
Correct socket planning:
- increases household safety,
- reduces the risk of electric shock,
- makes everyday device use more convenient.
Which electrical safety zones apply in a bathroom?
The basis for planning bathroom sockets is dividing the room into safety zones. Each zone defines which electrical equipment may be used there. Below is a simplified overview of the most important zones.
Zone 0 – inside the bath or shower tray/shower enclosure
This zone has direct contact with water. Installing sockets and standard electrical devices is prohibited here.
Only devices with a very high protection rating (at least IPX7) intended for underwater operation are permitted.
Zone 1 – immediate area around the bath or shower
This zone includes the space up to 60 cm around the bath or shower enclosure, as well as the area above it.
Only equipment protected against water jets may be installed here (at least IPX5). Sockets are still not permitted.
Zone 2 – increased moisture zone
This is the area from 60 cm to around 2.25 m from the bath or shower, and also the area around the washbasin.
In this zone, selected electrical components with an appropriate protection rating can be installed, but standard sockets are still not recommended.
Zone 3 – safe zone for sockets
This is the “driest” part of the bathroom, away from water sources. This is where space is intended for:
- sockets,
- light switches,
- connecting the washing machine and other appliances.
Bathroom sockets should be installed only in Zone 3. Ignoring this rule creates a real danger to health and life.
At what height should sockets and switches be installed in the bathroom?
Besides zones, installation height matters too. The right position improves safety and comfort. The most common solutions are:
- sockets – approx. 120 cm above the floor,
- light switches – approx. 140 cm,
- lights – at least 200 cm.
This layout reduces the risk of water contact and makes everyday use easier.
Washing machine socket – where should it go?
The washing machine socket must also be in Zone 3, at a safe distance from water sources. It’s often placed:
- behind the washing machine,
- in the adjacent cabinet,
- in a furniture cover/niche.
This keeps the installation safe and the socket less exposed to splashes.
Which sockets are suitable for bathrooms?
Any socket installed in a bathroom should be protected against moisture. Standard practice is models with a protective flap.
In practice, that means:
- IP44 rating or higher,
- a spring-loaded flap that closes automatically,
- a housing resistant to water splashes.
These solutions significantly improve everyday safety.
Why is correct bathroom socket installation so important?
A poorly planned bathroom electrical installation isn’t just an aesthetic issue. It’s a real risk of faults, electric shock, and costly rework after the renovation is finished.
Well-planned sockets:
- work reliably for years,
- help avoid improvised extension leads,
- give everyone at home a greater sense of safety.
Bathroom sockets require a thoughtful plan and compliance with applicable standards. The right zones, the right mounting height, and splash-protected fittings help keep the bathroom safe and comfortable for everyday use.
It’s one of those details you don’t notice at first glance, but it makes a big difference over the years.
Check out the Rea range and plan your bathroom in one place — from fittings and lighting to solutions that support safe everyday use. This helps you avoid random decisions and achieve a cohesive, well-thought-out result.
FAQ
Can you install a socket near the washbasin?
Yes, but only in Zone 3 and with sufficient distance from the water source.
What IP rating should a bathroom socket have?
At least IP44, i.e., protection against water splashes.
Can the washing machine socket be behind the appliance?
Yes, that’s one of the most common and safe solutions.
Can sockets be installed in Zone 1 or 2?
No. Sockets are permitted only in Zone 3.
Can you install bathroom sockets yourself?
The installation should always be carried out by a qualified electrician — it’s about safety.
