Könighaus infrared heater in a bathroom
Updated: 22 October 2026
You saw bathroom on a bullet and a towel rail in the photo, and you are asking whether that means a plug beside the bath. Smart Dual listings in this set print IP44. P-series pages name the room and do not print an IP code. British wiring uses zones and a fixed connection, not a marketing word. The [Könighaus infrared heater comparison](/hub/heating/konighaus-infrared-heater) shows which row prints IP44. Peter F. checked the listings and public UK sources. There was no lab test. A qualifying purchase can earn a commission at no extra cost to you.

What the listing means by bathroom
The 450 W, 600 W and 800 W Smart Dual listings print IP44 and mention humid rooms and a towel rail. IP44 is a dust and splash test. It is not permission to install the panel anywhere in a wet room.
The P-600 and P-800 amazon.co.uk pages name bathroom in places and do not print an IP code or a towel rail. Könighaus’s 2023 English manual still rates those types as IP44, and the manufacturer page prints IP44 with a hot-surface warning. Keep both facts: the manual, and the empty field at checkout.
None of the listings draw a zone diagram. SELECT’s guide to BS 7671 Section 701 does. Which carton has the rail is on Könighaus Smart Dual vs P-series.
Zones, in plain distances
Under BS 7671:2018+A2:2022 Section 701, zone 0 is the interior of the bath or shower basin. The SELECT guide expects IPX7 and SELV there. Zone 1 runs above the bath or tray to 2.25 m, or to a higher fixed shower head. Zone 2 is the next 0.6 m. Equipment in zone 1 or 2 must be fixed, permanently connected, and at least IPX4.
A panel on feet does not meet that fixed-connection rule, even with IP44 on the sticker. IP44 is not permission for zone 0. Sketch the bath, measure 2.25 m up, then 0.6 m beyond zone 1, before you decide where a rail could go.
The socket and the towel rail
A 13 A socket on a bathroom circuit must sit at least 2.5 m horizontally from the zone 1 boundary, with 30 mA RCD protection in the SELECT summary. That often puts a plug well away from the wet area.
The Smart Dual towel rail does not move the zone boundary. A towel across the radiant face still breaks the do-not-cover rule. Manufacturer pages quote a surface around 75–125 °C. Everyday clearances are on how to use a Könighaus infrared heater.
Who is allowed to wire it
Electrical Safety First treats bathroom electrical work as a Part P and competent-person job. GOV.UK notes that work around baths and showers is notifiable unless a registered installer does it. That Part P framing is England’s. Scotland and Northern Ireland use their own building-control routes.
A plug into an existing socket outside the zones is not the same job as a fixed heater in zone 1. Zone 1 is electrician territory: a permanent connection, IPX4 equipment, and certification. If the panel could fall into the bath, do not run it. The Smart Dual sheet warns against that placement.
Common questions
Does IP44 mean I can put it in the shower?
No. Zone 0 is the interior of the bath or shower basin and requires immersion-suitable equipment, IPX7 and SELV in the SELECT guide’s table. IP44 is a splash rating on the product. It is not a shower approval, and it does not allow the panel inside the tray or the bath.
Which models in this set print IP44 on amazon.co.uk?
The three Smart Dual listings print IP44: 450 W, 600 W and 800 W. Each also lists a towel rail or holder. The two P-series amazon.co.uk rows do not print an IP field, and they do not list a towel rail. Bathroom as a room type on those pages is not the same as an IP code.
The P-series manual says IP44. Why is the amazon field empty?
The manufacturer site and the 2023 English manual can rate type P-600 and P-800 as IP44 while a given amazon.co.uk spec table omits it. Buy on the page you can screenshot, and read the manual before you assume bathroom suitability. An empty listing field is what you see at checkout. It is not proof the manual is blank.
Can the towel rail hang over the bath?
Zone rules depend on distance and on how the panel is fixed, not on the marketing photo. A rail above zone 1 still needs compliant fixed wiring by someone qualified. The rail does not move the 2.25 m or 0.6 m boundaries, and it does not turn a plug-in panel into permanently connected equipment.
Where may a 13 A socket sit?
At least 2.5 m horizontally from the zone 1 boundary, in the SELECT summary of bathroom circuits, with 30 mA RCD protection. That distance often puts a plug well away from the wet area you hoped to warm. A socket inside the zones is not a workaround for a panel that should be fixed.
Is plugging in outside the zones the same as a fixed connection in zone 1?
No. Zone 1 expects fixed, permanently connected equipment of at least IPX4. A portable plug-in panel, even with IP44 and feet in the carton, is a different compliance path. It still needs a sensible check on load and RCD protection if you use an existing socket outside the zones.
Does Part P apply the same in Scotland and Northern Ireland?
Part P is the familiar England framing for notifiable work around baths and showers, unless a registered installer does the job. Scotland and Northern Ireland use their own building-control systems. Check the rules where the bathroom is, rather than treating one UK paragraph as enough.
What if the panel could fall into the bath?
Do not use it until the mounting is secure and away from paths where it could fall into water. The Smart Dual manual warns against that placement. A towel rail and an IP44 sticker do not remove the risk if the panel is only standing on feet beside the bath.
