The best bathroom fan heaters, compared.
Top pick: Dreo DR-HSH017S Best value: TCP Smart 2000 W – About £60 with 220–240 V, IP22, 2000 W and a remote printed, at 4.3 from 137 reviews. IP22 and a power-cut restart still count against it. Updated October 2026.
A bathroom fan heater in UK shops is usually a wall-mounted downflow unit that blows warm air for the length of a shower. It is not a desk heater and not a heated towel rail. You look at one because a radiator or towel rail leaves a tiled room cold for the first ten minutes. Judge the page by the printed IP code, the plug or fused spur, a run-back timer, and a real 1 kW and 2 kW choice. The word bathroom in the title is not enough. In zones 1 and 2, BS 7671 Section 701 asks for at least IPX4. IP22 on tarm aTCP listings is a weaker water digit. The [IP rating guide](/hub/portable-heaters/bathroom-fan-heater/sub/bathroom-fan-heater-ip-rating) sets that line out on its own. A hard-wired bathroom heater is a job for a registered electrician.

Question 1 of 2
What is already on the wall?
The Dreo DR-HSH017S is a wall ceramic heater at about £119.99, rated 4.6 from 2,962 amazon.co.uk reviews, with a claimed 28 dB, 30° oscillation, a remote, the Dreo app and a 24-hour timer. The room-type field includes a bathroom and the bullets print IP24, which matches the water digit Section 701 names, but the listing does not say the heater is suitable for zone 1. Of the first 50 reviews, most describe workshops, cabins, garages or conservatories rather than bathrooms, so the star count is not a bathroom sample. The voltage field says 120 V and the thermostat field is in Fahrenheit, while reviewers quote Celsius controls and a label that reads 2000 W against a 1500 W heat-output field. One review mentions about 30 seconds of cool air after switch-off. One kitchen user says the highest setting barely took the chill off an uninsulated room at 3 °C indoors. A shed left on overnight reached 33 °C in one report, which is the risk of a 24-hour timer rather than a 30-minute run-back. At this price you are paying for a quiet wall fan with IP24 on the page, and you still have to read the carton for 220–240 V before it goes near a UK bathroom.
Pros
Cons
Best for: You want a quiet IP24 wall ceramic for a cabin or a bedroom, and the carton in your hand says 220–240 V.
Less suitable: You want a hard-wired bathroom downflow with a short run-back, or you cannot confirm a UK mains voltage on the carton.
Specifications
Common questions
What IP code does the Dreo print?
IP24. The bullets name bathrooms. They do not say zone 1.
What wattage is printed?
The heat-output field says 1500 watts. One review says the product label reads 2000 watts.
What voltage is printed?
The voltage field says 120 volts.
The Winterwarm WWDF20E is the downflow in this set with a bathroom review file behind it: about £59.99, 4.4 from 1,104 amazon.co.uk reviews, IP22, a pull cord and a stated 30-minute run. The bullets set 1 kW or 2 kW at installation, quote 12–20 m², and say there is no plug, only three-core wiring to a fused spur with an earth. Many of the first 50 reviews describe quick heat in a small bathroom or toilet, and several say the fixing points match an older Dimplex or Creda. That same sample keeps returning to a weak pull-cord switch that fails within months to a couple of years, including one buyer who says every unit failed in 12–18 months with snapped cords. Several units arrived on 1 kW and felt weak until the internal switch was moved, and some cut out after a few minutes instead of 30, which reviews link to dust. The listing says no cable, yet several reviews describe a cable that was hard to remove or too short. One review says the 2 kW setting blew the fuse on the circuit board. IP22 is printed, and it is not an IPX4 approval for zone 1. In this set it is the top pick when a fused spur is already on the wall.
Pros
Cons
Best for: You already have a fused spur high on the wall and you want a 30-minute pull-cord downflow, accepting IP22 and the cord fault in the reviews.
Less suitable: You need IPX4, a plug-in heater, or a cord mechanism the reviews have not already worn out.
Specifications
Common questions
Does the Winterwarm have a plug?
The listing says no plug, and that it needs three-core wiring to a fused spur with an earth.
How long does it run?
The title and bullets state a 30-minute automatic run.
Where is the 1 kW or 2 kW choice?
The bullet says the two settings are set at installation. Reviews say some units arrived on 1 kW.
The TCP Smart downflow, model SMAWHHEAT2000WHOR705, is about £60 with 4.3 from 137 amazon.co.uk reviews. It prints 2000 W, IP22, 220–240 V AC and a claimed 15 m², with a remote in the box and app control for Alexa, Google Home and Siri. Many of the 41 review texts say a small bathroom is warm within a few minutes, and several mention an electrician fitting it to the wall. The spec table does not state a plug, but reviews describe a fitted 13 A plug on a short flex of about 1.5 m or 2 m, which two buyers had to open or cut before a hard-wire. Several reviews say the temperature reading drifts and has to be reset, and more than one notes about 60 seconds of cool air after switch-off. One detailed review says the heater turned itself on after a power cut and heated a workshop overnight. Two reviews say a unit stopped within about five or six months. The bullets call IP22 suitable for bathrooms, but that water digit is not the IPX4 line Section 701 asks for in zones 1 and 2. In this set it is the best value when the voltage line is already 220–240 V.
Pros
Cons
Best for: You want a smart downflow at about £60 on a printed 220–240 V supply, and you accept IP22 plus a plug an electrician may have to deal with.
Less suitable: You need a stated IPX4 rating, or a heater that must stay off after a power cut.
Specifications
Common questions
What IP code does the TCP print?
IP22. The bullets call that suitable for bathrooms. That water digit is not the IPX4 line for zones 1 and 2.
Does it come with a plug?
The spec table does not say. Reviews describe a fitted 13 A plug on a short flex, about 1.5 m or 2 m.
What voltage is printed?
The size bullet says 220–240 V AC.
The Eterna DFHT2KW is listed at about £41.99 as a 2 kW downflow bathroom heater with a run-back timer, and amazon.co.uk shows 4.3 from 99 reviews. Reviewers use it as a replacement for an existing wall downflow, including a Dimplex FX20 whose top fixing centres matched. The internal 1 kW / 2 kW load switch and dip switches for the timer are what those reviews describe. One reviewer says the run stops at about 15 minutes, while the maker’s trade sheet, which is not the amazon table, allows a run-back of up to 35 minutes. The amazon file prints no IP code and no voltage. Two buyers returned the heater because the instructions said it was not suitable for bathrooms, which matches a published copy of that sheet excluding zones 0, 1 and 2. One unit cut out every 10–15 seconds after a paid installation, and two reviews call the terminal block cramped, with one saying no power cable was in the box.
Pros
Cons
Best for: You are replacing a downflow on a wall outside zones 0, 1 and 2, and an electrician is fitting the terminal block.
Less suitable: You need a heater the instructions allow inside a bathroom zone, or a printed IP code.
Specifications
Common questions
Does the listing say the Eterna is for a bathroom?
The title says bathroom heater. Two reviews say the instructions say it is not suitable for bathrooms.
How is the output set?
A bullet states an internal 1 kW / 2 kW load switch.
Is an IP code printed?
No. The amazon.co.uk file does not print an IP code.
The Sandrem XD-2060HA is a wall and desk ceramic fan at about £38.94, rated 4.2 from 11 amazon.co.uk reviews, with 2000 W, 1000 W and a cool-air setting on a knob. Seven review texts are in the file, and several of them use it in a bathroom, a toilet or a shower room, including one that replaced an old bar heater. The voltage field prints 120 V and 12 A, with a thermostat in Fahrenheit, which is not a UK mains line. No IP code is printed, and one review claims a splash-proof design that the listing itself does not support. One buyer could not wall-mount it because the plug lead was too short and the sealed back stopped a lead change. Another bathroom user says there is no timer. Coverage is printed as 20–30 m² and also as both 150 and 750 square feet, so the room-size lines do not agree.
Pros
Cons
Best for: You want a cheap ceramic wall fan for a dry room, and you can confirm the carton says 220–240 V before you fit it.
Less suitable: You need a printed IP code, a timer, or a lead long enough for a high bathroom wall.
Specifications
Common questions
Does the Sandrem listing print an IP code?
No. The Sandrem file has no IP code.
Is there a timer?
The spec table does not state a timer, and one review says there is none.
What voltage is printed?
The voltage field says 120 volts.
Five amazon.co.uk bathroom fan heater listings were scored from the UK star line, then from whether the review sample is actually about bathrooms, from a printed IP code, a voltage field that matches UK mains, a run-back rather than a 24-hour timer, and a supply you can act on. A lower shelf price only helps when those lines are still present. A 120 V field, or instructions that exclude bathroom zones, cancels the cheap price. There was no lab test. IP22 is not scored as if it met the IPX4 line in BS 7671 Section 701. The Ofgem unit rate is arithmetic for a half-hour at 2 kW, not a point on the score. The five weights below sum to 100.
Amazon evidence
25%The amazon.co.uk star rating, then whether the sampled reviews are about bathrooms. A 4.6 from a large file of cabins and workshops does not outrank a 4.4 whose texts are bathrooms.
IP code
25%A printed IP code, read against the IPX4 water digit Section 701 asks for in zones 1 and 2. IP22 is a weaker water digit. No printed code scores down.
Voltage and supply
20%A voltage field that matches UK mains, and a supply you can act on: a fused spur with an earth, or a described 13 A plug. A 120 V field scores down.
Timer and output
15%A run-back of about half an hour, and a real 1 kW and 2 kW choice. A 24-hour timer is a different risk in a wet room.
Price
15%A lower shelf price in GBP only helps when the IP code, the voltage and the supply line are still present.
A bathroom fan heater is a short blast of warm air for a tiled room, not a towel rail and not a desk heater. Start with the IP code and the supply. The word bathroom in the title comes after those two lines.
A bathroom fan heater, in UK shops, is usually a wall-mounted downflow fan that blows warm air for the length of a shower. It is not a portable desk heater and not a heated towel rail. You buy one because a radiator or towel rail leaves a tiled room cold for the first ten minutes. This comparison keeps five amazon.co.uk listings, from about £38.94 to £119.99. The Winterwarm WWDF20E and the Eterna DFHT2KW are downflow units. The TCP Smart is a smart downflow at about £60.
The Eterna title says bathroom, and two reviewers say the instructions say it is not. The Sandrem title says bathroom and prints no IP code. IP22 on the Winterwarm and the TCP is dripping water at a tilt, not the IPX4 splash digit Section 701 asks for in zones 1 and 2.
UK mains are 230 V nominal. The Sandrem and Dreo voltage fields print 120 V. One Dreo review says the label reads 2000 W, not the 1500 W field. Fit neither until the carton says 220–240 V and the plug is BS 1363 or the spur is proper.
Several Winterwarm reviews say the unit arrived on 1 kW and felt weak until the internal switch was moved. Do not use an extension lead to reach a socket. Call an electrician for any hard-wired bathroom heater, for a fused spur, when 2 kW opens a fuse, and when the label voltage does not match UK mains.
Section 701 of BS 7671:2018+A2:2022 requires at least IPX4 in zones 1 and 2, and IPX5 if water jets are likely. Zone 0 is inside the bath or shower. Zone 1 is above it to 2.25 m, or higher if the fixed shower head is higher. Zone 2 is 0.60 m beyond zone 1. Digit 2 is dripping water at a tilt. Digit 4 is splash from any direction. The Winterwarm and the TCP print IP22. Their bullets are not an IPX4 approval for zone 1.
The Winterwarm states no plug and three-core wiring to a fused spur with an earth. That is a registered electrician’s job. In England and Wales it is notifiable bathroom work under Part P. That rule is not a map you can paste onto Scotland. TCP reviews describe a 13 A plug on a short flex. SELECT’s guide allows 13 A sockets only beyond 2.5 m from the zone 1 boundary, with a 30 mA RCD. Do not use an extension lead. UK mains are 230 V nominal.
Three typical situations, each with a recommendation from this comparison.
You already have a fused spur high on the wall and you want a pull-cord downflow with a stated 30-minute run. The Winterwarm WWDF20E at about £59.99 prints 240 V and IP22. Accept the pull-cord fault in the reviews, and that IP22 is not IPX4.
You want a smart downflow at about £60 with 220–240 V, IP22 and a remote printed on the listing. The TCP Smart fits that page. Reviews describe a short flex and a 13 A plug an electrician may have to open, and one unit came on after a power cut.
You are replacing a wall downflow outside zones 0, 1 and 2, and an electrician is fitting the terminal block. The Eterna DFHT2KW at about £41.99 has a run-back and an internal 1 kW / 2 kW switch. Two reviews say the instructions exclude bathroom zones, and no IP code is printed.
The top pick is the Winterwarm WWDF20E at about £59.99. It has the highest score in this set: 4.4 from 1,104 amazon.co.uk reviews, many of them bathrooms, with 240 V, IP22, a pull cord and a stated 30-minute run. Pull-cord failure is the repeated complaint, and IP22 is not the IPX4 water digit for zones 1 and 2. The best value is the TCP Smart at about £60. It prints 220–240 V, IP22, 2000 W and a remote, at 4.3 from 137 reviews. The score is held down by IP22, a short flex, thermostat drift, and a unit that came on after a power cut. The Dreo prints IP24 and 4.6 from 2,962 reviews, but the voltage field says 120 V and most of the sampled texts are not bathrooms. None of these scores is a lab test.
TCP Smart 2000 W
About £60 with 220–240 V, IP22, 2000 W and a remote printed, at 4.3 from 137 reviews. IP22 and a power-cut restart still count against it.
