Bathroom wall fan heater

Updated: October 2026

You want warm air in a room with a bath or shower, and the amazon.co.uk title already says bathroom. That word does not say whether the heater may sit on your wall. A bathroom wall fan heater in zones 1 and 2 needs at least IPX4 and a manual that allows that zone. IP22 and IPX2 fail that test. Models and prices are on the [wall fan heater comparison](/hub/portable-heaters/wall-fan-heater). A qualifying purchase can earn us a commission at no extra cost to you. Updated 16 October 2026 from amazon.co.uk listings, SELECT, NICEIC, and Approved Document P. We did not test splash resistance.

Zones before the product title

Stand in the bathroom and place the bath or shower tray before you trust a listing. Zone 0 is the interior of the bath or shower basin. Nothing in this comparison belongs there. Zone 1 is the space above the bath or tray. Zone 2, on the SELECT Section 701 guide and on NICEIC’s householder page, is the 0.6 m band beyond zone 1, up to 2.25 m from the floor or to the height of a fixed shower head if that is higher. Equipment in zones 1 and 2 needs at least IPX4, and the manufacturer’s instructions still have to allow that zone. If you cannot say the wall is outside zone 2, measure before you buy.

IP22, IPX2, and IP24 in this set

The second digit is the water test. IPX4 means splashing water. IPX2 means dripping water. IP22 uses that same water digit as IPX2. The Winterwarm WWDF20E is listed as IP22, a 2 kW pull-cord downflow at about £59.99 with no plug. Both MYLEK model 272190 listings are also IP22, at about £63. A line about a qualified electrician does not raise IP22 to IPX4. The MYODH2000 and MYOD5208 are listed as IPX2, with UK plugs, at about £62.99. The Dreo DR-HSH017S states IP24, which meets the water digit, at about £119.99. You still need the manual to allow the zone. The Eterna and the Dreo DR-HSH009S have no IP rating in the stored file. One Eterna reviewer was told the heater is not suitable for a bathroom. If the title and the manual disagree, follow the manual.

Plug, spur, and RCD

Ordinary 13 A sockets are not allowed within 2.5 m of the zone 1 boundary, so a small British bathroom often has nowhere to plug in. A MYLEK lead of about 1.5 m then has nowhere legal to go. Do not run an extension into the room, and do not leave a reel coiled. Circuits in the room need 30 mA RCD protection. Outside the zones, Section 701 does not add a further IP minimum, and the manual still applies. The Winterwarm is the spur-only heater here: 3-core cable, earth, no plug, 240 V. Fitting that is an electrician’s job if you are not competent to do it. How a first run should feel is on the how to use a wall fan heater page.

When England’s Part P applies

In England, Approved Document P treats a new circuit, a replacement consumer unit, or an alteration in a bathroom as notifiable. A competent-person electrician can self-certify. A like-for-like swap on an existing spur is a different job from cutting in a new spur beside the bath. If you are altering wiring in that room, book the electrician before you buy a spur-only heater you cannot connect. Scotland and Northern Ireland have their own building regulations. Do not copy England’s notification list across the border.

Common questions

Can any heater sold as a bathroom heater go next to the shower?
No. Zones 1 and 2 need at least IPX4, and the manufacturer has to allow that zone. A bathroom in the title is not that rating. In this set, IP22 and IPX2 listings fail the water digit for those zones. The Dreo DR-HSH017S states IP24, which meets the digit, and you still have to read the manual and confirm the plate is 220–240 V. Nothing here belongs inside the bath.
Is IP22 the same as IPX4?
No. IP22 and IPX2 are not the splash rating. IPX4 is the minimum SELECT and NICEIC describe for zones 1 and 2. The Winterwarm and the MYLEK 272190 pair are listed as IP22. The MYODH2000 and MYOD5208 are listed as IPX2. Those codes can be fine outside the zones, if the instructions agree. They are not a zone 2 heater. IP24 is the code in this set that carries the X4 water digit.
Where can an IP24 heater go?
Only where the manual allows, on a supply the plate is rated for. IP24 on the Dreo DR-HSH017S meets the water digit for zones 1 and 2. It is not permission to hang the heater inside the bath, and it does not fix an attribute table that says 120 V. The circuit still needs 30 mA RCD protection. If the manual is silent or says the heater is not for bathrooms, do not mount it in one.
Can I plug a heater into a bathroom socket?
Only if that socket is at least 2.5 m outside the zone 1 boundary and the heater’s IP rating and manual allow the spot where it hangs. Many small bathrooms have no such socket. A 1.5 m MYLEK lead will not reach a socket on the landing without an extension, and an extension into the bathroom is the wrong fix. A shaver socket is not rated for a 2 kW heater.
Is a like-for-like swap notifiable in England?
A straight replacement on an existing connection, with no new circuit, is not the case Approved Document P lists as notifiable. A new circuit, a new consumer unit, or an alteration in the bathroom is notifiable in England. If you are cutting in a spur that was not there, ask an electrician before you buy. A competent person can self-certify the notifiable work. Do not apply this list unchanged in Scotland or Northern Ireland.
