Bath renovation – how to restore an old cast-iron or acrylic bath?

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 clearly define where and which types of sockets may be installed.

Proper socket planning:

• improves household safety,
• reduces the risk of electric shock,
• makes everyday appliance use more convenient.

Which electrical safety zones apply in a bathroom?

The basis for planning sockets in a bathroom is dividing the space into safety zones. Each zone defines which electrical equipment may be installed there. Below is a simplified overview of the key zones.

Zone 0 – inside the bath or shower tray/shower enclosure

This zone has direct contact with water. Installing sockets and standard electrical devices here is prohibited.

Only devices with a very high protection rating (at least IPX7), designed to operate under water, are permitted.

Zone 1 – the immediate area around the bath or shower

This zone covers the space up to 60 cm around the bath or shower enclosure, including the area above it.

Only equipment protected against water jets (at least IPX5) may be installed here, but sockets are still not allowed.

Zone 2 – the higher-moisture zone

This is the area from 60 cm to around 2.25 m from the bath or shower, as well as 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 – the 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,
• connections for 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 a bathroom?

Besides the zones, installation height matters. Correct positioning improves both safety and comfort. Most commonly, the following solutions are used:

• 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 daily use easier.

Socket for a washing machine – where should it go?

The washing machine socket also needs to be in Zone 3, at a safe distance from water sources. It is most often placed:

• behind the washing machine,
• in the adjacent cabinet,
• inside a furniture panel/niche.

This keeps the installation safer and the socket less exposed to splashes.

Which sockets are suitable for a bathroom?

Any socket installed in a bathroom should be protected against moisture. The standard choice is a model with a protective flap.

In practice, that means:

• IP44 rating or higher,
• a spring-loaded flap that closes automatically,
• a housing resistant to splashing water.

These solutions significantly increase everyday safety.

Why is correct socket installation in a bathroom so important?

A poorly planned bathroom electrical installation isn’t just an aesthetic issue. It’s a real risk of failures, electric shock, and expensive rework after a renovation is finished.

Well-planned sockets:

• work reliably for years,
• reduce the need for improvised extension leads,
• give everyone in the home a greater sense of safety.

Bathroom sockets require a thoughtful plan and compliance with applicable standards. The right zones, the right installation height, and splash-protected fittings help ensure the bathroom stays safe and comfortable day to day.

It’s one of those details you don’t notice at first glance, but it makes a big difference over the long term.

Explore the Rea range and plan your bathroom in one place — from fittings and lighting to solutions that support safe everyday use. This way you avoid random choices and achieve a consistent, 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 splashing water.

Can the washing machine socket be behind the appliance?

Yes — it’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 a safety matter.
