300W infrared heater bathroom

Updated: 22 October 2026

You are planning a bathroom, and the amazon.co.uk panel listings mention splash resistance, bathrooms, or IP54. A 300W infrared heater bathroom search needs a yes-or-no with conditions, not a wattage boast. Section 701 of BS 7671 divides the room into zones where ordinary sockets and plug-in leads stop being simple DIY. The [300W infrared heater comparison](/hub/heating/300w-infrared-heater) shows what each of the four listings prints. This page holds the zone map and the socket rules. A qualifying purchase through our amazon.co.uk links can earn us a commission at no extra cost to you.

Where a bathroom panel is even allowed

NICEIC’s householder guide describes zones 0, 1, and 2 around a bath or shower. Zone 0 is inside the bath or shower basin. Zone 1 is above the bath or shower to 2.25 m. Zone 2 extends 0.6 m beyond zone 1, also to 2.25 m. A shower curtain does not shrink the zone. Fixed equipment in zones 1 and 2 needs at least IPX4, and IPX5 where water jets are used, per IET Section 701 and SELECT’s bathroom guide. Zone 0 and zone 1 are not places for a plug-in panel on a 1.8 m lead. Herschel’s Select XLS manual, for a different 300 W panel, allows zone 2 or outside the zones, never zone 0 or 1, and only with hard-wiring by a competent person. That permission is for Herschel’s product, not for a Hocosyme or Byekalt bullet.

IPX4, and what the four listings actually print

IPX4 means protection against splashes from any direction. IP44 adds solid-object protection to that splash rating. The rating plate wins if it disagrees with the listing. Hocosyme wall and portable bullets say IP54. Könighaus prints IP44 on a freestanding under-desk heater, which is not a bathroom design. Byekalt’s English bullets say dust and splash resistant and mention bathrooms, but they print no IP number. None of that replaces a zone decision. Splash resistant is not permission to plug in beside a bath. An IP54 claim still has to be installed in the right zone, on the right circuit, and often hard-wired.

Sockets, RCDs, and hard-wiring

SELECT’s bathroom guide puts ordinary socket-outlets, other than SELV, at least 2.5 m horizontally from the zone 1 boundary, with 30 mA RCD protection on bathroom circuits. A 300 W panel on a 1.8 m cable still needs a socket that is legally placed. If the only socket is inside the zone map, moving the panel closer is not a fix. An IET Wiring Matters FAQ once published 3 m from the zone 1 boundary. SELECT uses 2.5 m. Ask an electrician rather than averaging them. Removing a plug to hard-wire is electrician work. A UK review of Byekalt already describes bathroom fitting as taking the plug off for a professional install. Do not cut the plug yourself. A 30 mA RCD does not move a socket closer to water. Dry-room placement is on how to use a 300W infrared heater.

What to do with these four panels

None of the four listings is a bathroom design pack. Hocosyme’s IP54 bullets do not override socket distance. Könighaus IP44 describes a desk heater, not a wet-floor install. Outside the zones, on a socket that meets the distance rule and an RCD-protected circuit, you still need a rating that matches the room and a fixing that keeps towels off the hot face. Inside zone 2 you are in fixed equipment, IPX4 minimum, and almost certainly hard-wiring, with controls out of reach of the bath or shower. If the only plan is a plug beside the bath because a photo showed a bathroom, stop. For legs at a desk in a dry room, use the 300W infrared heater under a desk page.

Common questions

Can I plug a 300 W panel in next to the bath?
Not if the socket or the lead route falls inside the zone map, or closer than the socket distance rules allow. A splash bullet does not legalise the socket position. Zone 0 and zone 1 are not places for a casual plug-in panel on a 1.8 m lead.
What is zone 0, zone 1, and zone 2 in a normal UK bathroom?
Zone 0 is the bath or shower volume. Zone 1 is above the bath or shower to 2.25 m. Zone 2 extends 0.6 m beyond zone 1, also to 2.25 m. NICEIC’s diagram is the householder-friendly map. A shower curtain does not shrink any of those zones.
Is IP54 or IP44 or splash resistant enough on its own?
It is never enough on its own. Zone, mounting, circuit protection, and wiring method still decide whether the install is legal. The rating plate wins if it disagrees with the listing. Byekalt does not print an IP number at all.
How far must a normal socket be from the bath or shower?
SELECT’s guide uses 2.5 m from the zone 1 boundary for ordinary sockets, other than SELV. An IET Wiring Matters FAQ once published 3 m in a different context. Confirm the figure with your electrician against the current standard. Do not average the two numbers.
Can I cut the plug off myself?
No. Hard-wiring belongs to a qualified electrician. A UK review of the Byekalt panel already describes bathroom fitting as removing the plug for a professional install. Do not cut the lead to make a connection box look neat. Leave the plug intact.
Who do I call, and when do I stop?
Call a qualified electrician for any in-zone panel, any hard-wire, or any doubt about RCD protection or socket distance. Stop when the only plan relies on a plug in a wet area, or on a listing photo of a bathroom. All four panels here are the wrong evidence for a compliant layout.
