Bathroom radiant heater IPX4
Updated: October 2026
You want heat in a UK bathroom, and a listing has the word bathroom in a bullet. That word is not a zone rating. A bathroom radiant heater IPX4, in this amazon.co.uk set, means a listing that prints IPX4, and even then the bare wires are an electrician’s job. The [Vasner radiant heater comparison](/hub/portable-heaters/vasner-radiant-heater) includes two wall quartz heaters and two panels that mention a bathroom or an IP figure. Freestanding desk bars are the wrong tool. Listings were read on 15 October 2026. The Products Compared editorial team used those files, the IET’s Section 701 guide, and Approved Document P for England. This is not a lab test, and it is not a certificate that any ASIN passed BS EN 60335-2-30. A qualifying purchase can earn a commission at no extra cost to you. An electrician applies the current edition of BS 7671 on site. This page does not replace that.

What a bathroom listing has to state
IET guidance for locations with a bath or shower asks for equipment in zones 1 and 2 to be at least IPX4, and IPX5 where water jets are used for cleaning. Circuits of the location need 30 mA RCD protection. Fixed equipment in zone 1 has to be of a type the manufacturer allows there. IPX4 is splash protection. It is not zone 0, the interior of the bath or shower tray, and it is not a shower stream aimed at the heater. A bullet that says shower does not raise the rating.
In this set, only the Nedis HTBA10GY and the Mylek MY284858 state IPX4. The Stiebel Eltron IW 120 says bathroom or terrace in the bullets and states no IP figure. The Könighaus P-600 names a bathroom and states no IP figure. A missing number is not probably fine. It is a listing you do not treat as bathroom-safe on this evidence. VASNER’s own Citara M states IP44 on the manufacturer’s English page. That panel is not an amazon.co.uk ASIN here, and that IP44 is not printed on the Nedis, the Stiebel, the Mylek, or the Könighaus.
The general checks for watts and plugs, outside a bathroom, are on the buying guide. Here the first question is only whether an IP rating is written down.
Nedis and the missing plug
The Nedis HTBA10GY, ASIN B09RQX8S2F, is £34.99 and rated 4.3 from 434 reviews. The title and the bullets state IPX4. Heat is 600 W or 1,200 W, selected with a pull cord, and overheat protection is stated. No tip-over switch is stated, which is what you would expect from a heater that is screwed to a wall rather than stood on the floor. The customer note says it is shipped bare-wired, with no plug, and that it should be hard-wired to a fused connection. UK reviews repeat that an electrician was needed. A seller coverage line of up to 12 square metres is not a zone rule.
Do not fit a BS 1363 plug to those bare wires yourself. A plug-in domestic heater is a different product: it arrives with a UK 3-pin plug and a BS 1362 fuse. This one does not. Adding a plug does not invent an IP rating you already have, and it does put a flexible lead and a socket into a room where the zones, the RCD, and the fused connection are the electrician’s design. Do not open the case to reattach a pull cord if it comes off.
The bullets mention a shower. The rating stated is IPX4 only. If you wanted the heater inside the shower spray, this listing does not say that. The honest use is a wall the manufacturer allows, outside the direct spray, on a circuit an electrician has protected with a 30 mA RCD. Who should skip it for a desk or a rental with no permission to drill is on the best radiant heater page.
Stiebel, Mylek, and Könighaus
The Stiebel Eltron IW 120, £51.48, 4.1 from 490 reviews, is a wall quartz heater with 400 W, 800 W, and 1,200 W. The 5.2 A at 230 V matches the top output, so the watts are the coherent part of the file. The parts list is the heater, caps, a cable entry, a manual, rawl plugs, and screws. There is no mains lead. The indoor/outdoor field says indoor. The bullets say bathroom or terrace, and no IP figure is captured. That combination is not a bathroom candidate on this evidence. Until the manufacturer’s instructions give an IP rating, leave it off the bathroom wall.
The Mylek MY284858 is £99.99, 4.4 from 36 reviews, a 2,000 W mica panel that can be wall-mounted or freestanding. A bullet claims IPX4 and says a bathroom install should be done by a qualified electrician. The thermostat, timer, and app are real controls. The review count is small. Do not coil an extension lead under a 2 kW panel, in a bathroom or anywhere else. IPX4 on a freestanding panel does not mean you wheel it into zone 1 for a shower. Fixed equipment, where the manufacturer allows it, is the zone 1 case.
The Könighaus P-600 is £121.90, 4.0 from 23 reviews, a 600 W wall panel. A bathroom is named. No IP figure is stated. No thermostat is stated. The form-factor field says Tower while the title is a wall panel. One UK review says the brackets were missing and the panel arrived bent. It is not a bathroom candidate on this file. A five-year warranty bullet does not fill in the missing IP rating.
In England, Approved Document P makes a new circuit, a replacement consumer unit, or an addition or alteration in a special location around a bath or shower notifiable, unless a registered competent person self-certifies. That sentence is about England. Do not read it as the notification rule for Scotland, Wales, or Northern Ireland. Wherever you are in the UK, bare wires, a bathroom zone, and a new circuit are a call to an electrician, not an evening with a screwdriver.
Desk bars do not move into the bathroom
The Geepas GQH9106, the Warmlite WL42005, and the SONBION LSG13 are indoor floor heaters in these files. None states an IP rating. They state a tip-over switch because they stand on the floor, which is the wrong pattern for a bath or shower room. A glowing bar next to a towel rail is the scene the one-metre rule is written to prevent, and the bathroom adds water. Do not carry the Warmlite in from the landing because the bathroom is the cold room. How to use those bars in a dry room, including carpet and the grille, is on the how to use page.
The decision is narrow. Fit only a listing that states IPX4, only where the manufacturer allows that product, and only through an electrician who can see the zones and the RCD. In this set that starting point is the Nedis on a fused connection, or the Mylek if you accept 36 reviews and the electrician line in its own bullet. The Stiebel, the Könighaus, and the three desk bars do not clear the first check.
Common questions
Is IPX4 enough for a bathroom?
It is the minimum IET guidance cites for equipment in zones 1 and 2, with a 30 mA RCD on the circuits of that location. It is not automatically enough for every wall. The manufacturer has to allow the heater in that zone, and zone 0 is a different requirement. IPX5 is the figure associated with water jets used for cleaning. An electrician places the heater. The listing only starts the conversation.
Does IPX4 mean I can put the heater in the shower?
No. IPX4 is splash protection, not a shower stream and not zone 0 inside the bath or shower. The Nedis bullets mention a shower, and the stated rating is still IPX4 only. Do not mount it where the spray hits it because a marketing line used the word shower.
The listing says bathroom but has no IP rating. Can I still fit it?
Not on the evidence in these files. The Stiebel Eltron IW 120 and the Könighaus P-600 name a bathroom and do not state an IP figure. Treat that as not bathroom-rated. Do not borrow VASNER’s IP44 from the manufacturer site and apply it to these ASINs.
Why does the Nedis heater have no plug?
The customer note says it is shipped bare-wired and should be hard-wired to a fused connection. UK reviews say an electrician was needed. A bathroom heater that states IPX4 is often a fixed appliance, not a plug-in bar. The missing plug is the listing telling you the installation method.
Can I add a BS 1363 plug to the bare wires myself?
No. Do not put a 13 A plug on the Nedis or supply your own lead to the Stiebel and call it a portable heater. The connection, the fuse, the RCD, and the zone are electrical work. In England, work in the space around a bath or shower can be notifiable under Approved Document P.
Is the Stiebel Eltron IW 120 a bathroom heater?
The bullets say bathroom or terrace. The file does not state an IP rating, the indoor/outdoor field says indoor, and the box has no mains lead. That is not enough to treat it as suitable for zones 1 or 2. The watts are clearly stated. The splash rating is not.
Do I need an electrician, and is the work notifiable?
Yes, you need an electrician for bare wires, a bathroom zone, or a new circuit. In England, Approved Document P makes many of those jobs notifiable unless a registered competent person self-certifies. Notification rules differ outside England. Do not open a heater to reattach a pull cord, and do not stand a desk bar in the bathroom because it was cheaper.
