The bathroom is the only room where the standard specifies to the centimetre what is allowed.

Bathroom electrics in Amsterdam from € 685 including 21% VAT. The NEN 1010 zone rules decide which fitting, which socket and which IP rating is permitted at which distance from the bath. Use the zone checker below.

VAT display
Electrical work is always charged at 21% VAT. When does 9% or 0% apply?
The zones in plain language

The four zones explained, and the reasoning behind the 60-centimetre boundary.

The zone layout is about one question: how likely is water to reach it, and how likely are you to touch that thing while wet. The closer to the bath, the stricter.

Zone 0 — in het bad zelf

Inside the bath or shower tray

The volume inside the bath rim or shower tray. Here only SELV is allowed: maximum 12 volts AC, with the supply outside the zones. IP rating IPX7, so resistant to immersion.

toegestaanalleen 12 V SELV

Zone 1 — recht boven het bad

Directly above, up to 2.25 m

The space above zone 0 up to 2.25 metres height. Luminaires with at least IPX4 are allowed here, as are an electric boiler or a whirlpool pump. Sockets are not. For a shower without a tray, zone 1 is measured from the shower head.

minimaalIPX4

Zone 2 — zestig centimeter ernaast

0.6 m horizontally beyond zone 1

A band of sixty centimetres around zone 1, to the same height of 2.25 metres. IPX4 luminaires are allowed, mirror lighting is allowed, ventilation is allowed. An ordinary socket is not — only a shaver outlet with isolating transformer.

minimaalIPX4

Outside the zones

Outside the zones

The rest of the room. Here an ordinary socket is allowed, provided the whole bathroom circuit is protected by a 30 mA RCD. That last point is not advice but a requirement, and it applies to the whole bathroom.

mandatory30 mA RCD

Equipotential bonding

Supplementary bonding

All metal parts in the bathroom you can touch at once — water pipe, drain, radiator, bath — are bonded to each other and to earth. That way no voltage difference can arise between the tap and the bath.

Wat IPX4 betekent

Understanding IP ratings

The first digit is about dust, the second about water. IPX4 means resistant to splashing from any direction. IPX5 is a water jet, IPX7 immersion. Every fitting shows it; we check it at install against the zone it sits in.

X = not specified4 = spatwater

De uitzondering die veel mensen verrast

A bathroom without bath or shower — a toilet with only a basin — has no zones. There an ordinary socket may go anywhere, provided it is on a 30 mA RCD. The misconception runs the other way: many people think no socket is allowed anywhere in the bathroom. Outside the zones it is fine, and that is exactly where the washing machine belongs.

The item asked about most

Electric underfloor heating in a bathroom: cost, sequence and the mistakes to avoid.

For a bathroom of four to six square metres, electric underfloor heating is almost always the better choice over water. Installation costs are a fraction, you need no manifold, and the floor is warm within twenty minutes instead of two hours.

Wat het kost

€ 110 per square metre including the mat, floor sensor, programmable thermostat and connection on a dedicated circuit. For a five-square-metre bathroom that is about € 700. The floor finish itself is not included — the mat goes under the tile adhesive, so tiling continues as normal.

Where the mat does not go

Not under the bath, not under a fixed shower tray and not under furniture on the floor. The mat needs air circulation to shed heat; if it is enclosed it eventually fails. That means of five square metres of bathroom you heat three to four in practice — and that is enough.

The floor sensor is not optional

The thermostat measures floor temperature via a sensor that sits between the heating wires in a flexible conduit. That conduit exists so the sensor can be replaced in ten years without lifting the tiles. Installers who lay the sensor loose in the adhesive to save time cause a demolition job five years later. We always lay it in a conduit, with a bend large enough to pull a new sensor through.

Timing

The mat goes in after the floor is poured and levelled, and before the tiler arrives. We measure mat resistance three times: on delivery, after unrolling and after tiling. That way we know exactly when damage occurred — and that is the difference between an argument and a repair.

Dedicated circuit and thermostat

Underfloor heating gets its own circuit with RCD protection. The thermostat sits outside the zones, preferably next to the light switch by the door. Programmable is worth it: a bathroom that is warm at half past six and off again at nine costs a fraction of a floor that runs all day.

Water of elektrisch?

For a bathroom up to about eight square metres electric almost always wins on install cost and speed. For a larger room, or if you already have a boiler manifold nearby and the floor is thick enough, water can work out cheaper in use. We say honestly which of the two fits your situation — even if that is the variant we do not supply.

Mirror and lighting

Mirror lighting: from the front, not from above, and why that matters.

The classic problem: a spot in the ceiling above the mirror. It lights your forehead and puts your eyes in shadow. For shaving, make-up or checking a cut that is exactly wrong.

01

Verlichte spiegel

Backlit or edge-lit mirror

The neat solution: light that comes from the mirror itself, at eye height and from the front. Needs a connection behind the mirror at the right height — so the mirror size must be known before we pull the cable. IPX4 and on the bathroom circuit with RCD.

aansluiting € 165
02

Wandarmaturen naast de spiegel

Wall lights either side

Two luminaires left and right at about 1.70 m give the most even face light. Often in zone 2, so IPX4. Works better than one luminaire above the mirror, and looks calmer.

per luminaire €115
03

Algemeen plafondlicht

Ceiling lighting

Recessed spots with IPX4 where they fall inside the zones. Allow three to four spots in a five-square-metre bathroom, at 3,000 K — warmer light makes it harder to judge colour when shaving or putting on make-up.

per spot € 95

In practice: the switch belongs outside the zones

An ordinary wall switch is not allowed in zones 0, 1 or 2. In practice it therefore sits outside the bathroom, beside the door — or inside, but outside the zones. A ceiling pull cord is the classic solution in small bathrooms where no wall is outside the zones. And an occupancy sensor works less well in a bathroom than people hope: it no longer sees you when you lie still in the bath.

The part that prevents mould

Bathroom ventilation — the cheapest insurance against damp and mould.

In Amsterdam homes with a windowless bathroom, a good fan is the difference between clean joints and black edges. The electrical part is small work; the switching choice makes the difference.

Drie manieren om hem te schakelen

  • Met het licht mee, met nalooptijd. De eenvoudigste en meest gebruikte: de ventilator start met de lichtschakelaar en loopt tien tot vijftien minuten na. Werkt goed, tenzij u overdag doucht met het licht uit.
  • Met vochtsensor. The fan switches on by itself as soon as humidity rises above a set value, regardless of the light. More reliable, a little more expensive, and the better choice for a bathroom without a window.
  • Aangesloten op mechanische ventilatie. If you have a central system, a separate fan is usually unnecessary; then it is about adjusting the extract capacity in the bathroom.

Waar hij hangt

As high as possible and as far from the door as possible, so air is drawn through the whole room. In zones 1 and 2 with at least IPX4. Above the shower is allowed if the type is suitable — and that is on the type plate, not in the brochure.

Roosters en toevoer

A fan that extracts without make-up air does nothing. There must be a gap under the door of at least a centimetre, or a supply grille. This is the most common reason people think their fan is broken while it works fine.

Frequently asked questions

Frequently asked questions.

Is a socket allowed in the bathroom?

Yes, but not everywhere. In zones 0, 1 and 2 an ordinary socket is not allowed. Outside the zones — further than sixty centimetres from the bath or shower, or higher than 2.25 metres — it is fine, provided the bathroom circuit is protected by a 30 mA RCD.

In zone 2 one exception is allowed: a shaver outlet with an isolating transformer. That is a separate fitting, not an ordinary socket, and it costs € 225. A bathroom without bath or shower — a toilet with a basin — has no zones at all.

What does bathroom electrics cost?

Fully wiring a bathroom to the zone layout costs € 685 to € 1,250 including 21% VAT, depending on the number of points, lighting and chasing. That includes the dedicated circuit, cables, bonding, spots, mirror lighting, the fan and plaster-ready making good.

With five square metres of electric underfloor heating added you reach € 1,385 to € 1,950. The underfloor heating itself costs € 110 per square metre including mat, floor sensor, programmable thermostat and connection on a dedicated circuit.

Wat betekent IPX4 en waar heb ik het nodig?

An IP code has two digits: the first is about dust, the second about water. IPX4 means resistant to splashing from any direction; the X means dust is unspecified. IPX5 resists a water jet, IPX7 immersion.

In zones 1 and 2 IPX4 is the minimum for luminaires and fans. In zone 0 — in the bath itself — IPX7 applies and only SELV up to 12 volts is allowed. Outside the zones there are no special IP requirements. Every fitting shows the code; we check it at install against the zone it sits in.

May I put a washing machine in the bathroom?

Yes, provided the socket is outside the zones — further than sixty centimetres from bath or shower — and the circuit is protected by a 30 mA RCD. In practice that means the wall opposite the shower, or a niche.

What we often find is a washing machine on a two-pin socket without earth in a utility room or bathroom with a tiled floor. That is exactly the combination where a fault ends badly. Earth here is not a luxury but a requirement.

Where may the light switch hang?

Not in zones 0, 1 or 2. In practice the switch therefore sits outside the bathroom by the door, or inside but outside the zones. In a small bathroom where no wall is outside the zones, a ceiling pull cord is the classic solution.

An occupancy sensor works less well in a bathroom than people hope: it no longer sees you when you lie still in the bath, and then the light goes out. Fine for a toilet; for a bathroom with a bath we do not recommend it.

Is electric underfloor heating a good idea in a bathroom?

For a bathroom up to about eight square metres, almost always. Installation costs are a fraction of wet systems, you need no manifold, and the floor is warm within twenty minutes instead of two hours. € 110 per square metre including mat, sensor, thermostat and connection.

One caveat: the mat does not go under the bath, under a fixed shower tray or under furniture on the floor — it needs air circulation. Of five square metres of bathroom you heat three to four in practice, and that is enough.

What is equipotential bonding and is it mandatory in the bathroom?

Bonding all metal parts you can touch at once — water pipe, drain, radiator, bath rim — to each other and to earth. That way no voltage difference can arise between, for example, the tap and the bath.

It is required and costs € 145 per bathroom. In old Amsterdam homes it is almost always missing, and it is one of the cheapest things you can do for bathroom safety.

When should the electrician come during a bathroom renovation?

After the old bathroom is out and the walls are bare, and before the tiler arrives. Then we run the cables, fit junction and back boxes in their final positions, and test while everything is still open.

The underfloor mat goes in after the floor is levelled and before tiling. We measure resistance three times — on delivery, after unrolling and after tiling — so if damage occurs it is clear when. Then we return once more for finishing: spots, mirror, fan and switches.

Do you do bathroom electrics for English-speaking clients?

Yes. A bathroom wired to the NEN 1010 zone rules costs € 685 to € 1,250 including materials, labour, chasing, making good and 21% VAT, or € 1,385 to € 1,950 with five square metres of electric underfloor heating.

The zone rules are strict: nothing but 12 V SELV inside the bath, IPX4 minimum within 60 cm of it up to 2.25 m, no ordinary socket outlets in zones 0 to 2, and a 30 mA RCD on the whole bathroom circuit without exception. Use the zone checker at the top of this page, or send us a photo and we will tell you what is permitted where.
