Top pick: Mxmoonant 6 kW digital sauna heater – Highest listing score: one 6 kW figure, a 5–9 m³ band, no plug, and 4.4 from eight reviews. Best value: Mxmoonant 6 kW sauna heater – About £269 for the same 6 kW and 5–9 m³ band, with the dent on arrival already noted. Updated October 2026.
A 230 V sauna heater here is a complete electric stove: a metal body, elements, a stone space, and a temperature or time control. You are fitting a home cabin or replacing a stove. Facial steamers on the same shelf are left out. Judge a listing by one stated power, a room-volume band, a voltage a data plate can confirm, a clear no-plug note, and an honest stone weight. Every kept heater that states a kilowatt figure sits above a 13 A socket, about 2,990 W, so you start at the consumer unit. The check order is in the [230 V sauna heater buying guide](/hub/steam-baths/230v-sauna-heater/sub/230v-sauna-heater-buying-guide).
A 13 A plug is about 2,990 W, and Which? puts about 3,000 W on one socket.

The Mxmoonant WS-37-WJY is a 6 kW wall stove listed at £297 for a stated 5–9 m³ room. The amazon.co.uk line is 4.4 from eight reviews, and the one UK text in the file describes a quick warm-up as a replacement heater, a digital panel for time and temperature, and a timer that switches the stove off. The bullets say it does not come with a plug and that a licensed electrician should wire it, and they ask for 18–20 kg of stones that are not in the box. The same bullets list both 215–240 V single-phase and 380–415 V three-phase, so the links are not a guess you make from the title's 230 V. Eight reviews is a thin sample, and seven of those reviews are not in the file, so the praise is one owner's report rather than a pattern. The body is stated as 48 x 34 x 57 cm and 13.56 kg, which is a plausible stove.
Pros
One stated power, 6 kW, with a 5–9 m³ room band
4.4 from 8 amazon.co.uk reviews, with a UK text that describes a timer switching off
The listing says there is no plug and names an electrician
Body size 48 x 34 x 57 cm is a plausible stove
Cons
18–20 kg of stones are not included
Single-phase and three-phase are both printed, so the links still need an electrician
Only one written UK review is stored with the file
Best for: A home cabin in the stated 5–9 m³ band, where you can add a dedicated circuit and you want a digital timer described on the listing.
Less suitable: A flat with only a 13 A socket, a room outside 5–9 m³, or a first fit if you expected stones in the box.
The Anjur 39984 is listed at £172.22 as a dry wall stove with knobs on the front, a timer capped at 3 hours, and a claimed 110 °C. The title says 3–6 kW and the colour field says 4.5 kW, so the file does not give you one current to hand an electrician. The body is stated as 43 x 32 x 62 cm and 9.5 kg, which is a plausible stove size, and the bullets ask for 20 kg of stones that are not included. The amazon.co.uk line is 4.0 from a single review, and that review text is not in the file. Voltage is written as 220–240 V in the bullets and 220 V in the title, and a plug is not mentioned. The mounting line says about 18 cm from the ground, which is this listing's claim rather than a height you copy onto another stove. Hotel appears in the title and is not a commercial rating.
Pros
Stated body 43 x 32 x 62 cm and 9.5 kg
Internal knobs, a 3-hour timer, and a 110 °C claim are on the listing
20 kg of stones is named, even though they are extra
£172.22 is below the documented 6 kW Mxmoonant prices
Cons
Title power 3–6 kW conflicts with a 4.5 kW colour field
Only one amazon.co.uk review, and no review text in the file
No cubic-metre band and no plug sentence
Best for: A buyer who wants a dry wall stove with a stated 3-hour timer and will confirm the data-plate kilowatts before any circuit is designed.
Less suitable: Anyone who needs one kilowatt figure, a room band, or more than a single star rating before ordering.
The Mxmoonant WS-15-WJY is listed at £269 as a 6 kW wall stove for the same 5–9 m³ band as the dearer Mxmoonant. Three UK reviews in the file say it heats quickly and is easy to operate, and one owner fitted it in under 20 minutes because the rocks were already on site. The amazon.co.uk average is 3.8 from eight reviews, pulled down by a report of a large dent in the casing on a box that looked unmarked. The raw title says digital control, while the bullets say built-in time and temperature control and do not state a maximum number of hours. Stones are 14–18 kg and not included, and the listing says there is no plug. The 12.86 kg and 59.5 x 47.5 x 36 cm figures are package sizes, not a confirmed body.
Pros
£269 for a single 6 kW figure and a stated 5–9 m³ band
UK reviews describe a quick heat-up and a fit in under 20 minutes when rocks were already there
No plug is stated, with a licensed electrician recommended
Stone weight is named at 14–18 kg
Cons
One UK review reports a large dent on arrival
Stones are a separate purchase
The title says digital control and the bullets do not state a maximum timer
Best for: A 5–9 m³ home cabin if you already have sauna stones and you want the cheaper of the two documented 6 kW Mxmoonant listings.
Less suitable: Anyone who needs an unmarked case on arrival, a stated timer limit, or stones in the carton.
The Alvinlite stove is listed at £123.49, titled as 6 kW and 220 V with an internal thermostat. Two UK reviews are on the listing: one owner says it has been used numerous times and calls the purchase brilliant, and another says a corner arrived damaged, there were no instructions, and they should not have bought something this cheap while trying to wire it. The average is 3.5 from four reviews. The title says wet and dry, the listing questions ask the same thing, and the bullets do not add a stone weight, a timer limit, a cubic-metre band, or body dimensions. A heat-up of 30–60 minutes is claimed and depends on a room size the listing never states. A high Sauna Heaters rank does not fill those gaps.
Pros
One stated power, 6 kW, at £123.49
One UK reviewer reports repeated use
Internal thermostat is named in the title
Cons
A UK review says the box had no instructions and a damaged corner
No cubic-metre band, stone weight, timer limit, or dimensions
3.5 from only four reviews
Best for: A buyer who already has a manual from the maker and only needs a low shelf price for a stated 6 kW internal-control stove.
Less suitable: A first cabin, because wiring without instructions is the point where this listing should stop.
The HUUM Hive 9 kW listing is £1,300 and states a 9–15 m³ room, a Uku 3 app console for iOS and Android, and a 5-year warranty in the bullets. The heater is listed at 13 kg and 45 x 45 x 80 cm, which is a plausible body, and the connection line says 230 V Europe standard rather than a BS 1363 plug. Stones and the main power cable are both excluded. There is no star rating and no review text on the amazon.co.uk file saved for this comparison. Dealer pages for HUUM heaters quote different warranty and supply figures, and those figures are not part of this listing. The capacity field says 120 kilograms under a label that says capacity, not a stone weight.
Pros
One stated power, 9 kW, with a 9–15 m³ band
Uku 3 app control for iOS and Android is claimed on the listing
Body size 45 x 45 x 80 cm and 13 kg is plausible
The bullets say stones and the mains cable are not included
Cons
£1,300 with no amazon.co.uk review line in the file
Stones and the main power cable are both extra
The voltage line says 230 V Europe standard, not a UK plug
Best for: A larger home cabin in the stated 9–15 m³ band, if you accept the amazon listing on its own and you will buy cable and stones separately.
Less suitable: A buyer who wants UK owner reviews, a fitted plug, or a 6 kW stove for a smaller room.
This Generic listing is £199 and puts 8 kW in the title parenthesis after a 3–9 kW range. The bullets then print four room bands, including 8 kW for 8–12 m³, so you cannot treat the page as one data plate. It claims an external mechanical knob to 90 °C, a programmable timer, wet and dry use, and professional wiring, with 14–20 kg of stones sold separately. There is no star rating and no review text. The dimension field is 0.1 x 0.1 x 0.1 cm, which is not a stove, and the power-source field reads 11111. Voltage is not stated. The mounting line says about 10 cm above the floor, which belongs to this listing only.
Pros
An 8–12 m³ band is printed next to the 8 kW row
External knob, a 90 °C claim, and professional wiring are stated
Stone capacity is named at 14–20 kg, sold separately
£199 is below the copied listings near £290
Cons
The title mixes 3–9 kW with an 8 kW parenthesis
No reviews, no voltage, and dimensions of 0.1 cm
Several other kilowatt rows sit on the same page
Best for: Only if the seller confirms one power, one band, and a real body size before you ask an electrician to look.
Less suitable: A first order, because the page does not settle which stove is in the box.
The EVTSCAN listing is £281.41 for a stated 3.6 kW, 230 V stove with internal control. The bullets claim a stainless heating tube and nickel-chromium wire, and they say a little maintenance is required. There is no star rating, no room band, no stone weight, no timer, no plug, and no dimensions. The file dates the listing to 26 August 2021, and it still does not say what size of cabin the 3.6 kW is meant for. At this price you are near the Mxmoonant listings without their room band or their no-plug sentence. A 3.6 kW claim, if it is real, is already above a 13 A socket. Easy to install is a bullet, not a set of clearances.
Pros
One stated power, 3.6 kW, at a stated 230 V
Internal control is named
Heating-tube material is described as stainless steel
Cons
No reviews, room band, stone weight, timer, or dimensions
£281.41 for a sparse page
A plug is not mentioned
Best for: Only if you already know the cabin volume and the maker sends a manual that this listing does not contain.
Less suitable: A buyer choosing by price among 3.6 kW titles, because the page does not show what room it serves.
The DHONGGY listing is £298.17 and is the copied listing that does keep one power: 9 kW at 220–230 V, dry, with internal knobs, a 3-hour timer, and a 110 °C claim. It asks for 20 kg of stones that are not included. There is no review line and no cubic-metre band, so a 9 kW title is not a room match. The dimensions are 2.54 cm on each side and the weight is 5 kg, and the photo matches the ZXXDSGHUS and WDXQHY listings. A plug is not mentioned. Model number 098 is shared with those other two pages. At this price you are next to the Mxmoonant 6 kW listings, which at least state a room band.
Pros
Title and bullets both say 9 kW
A 3-hour timer and 20 kg of stones are named
220–230 V and dry use are stated
Cons
No cubic-metre band and no reviews
2.54 cm dimensions and a photo shared with two other listings
Model 098 and a 5 kg weight do not describe a distinct stove
Best for: Only after the seller replaces the 2.54 cm dimensions with a real body size and a room band.
Less suitable: A 9 kW cabin plan that treats this page as the same product as the HUUM listing because both titles say 9 kW.
The Generic listing prints £6.99 for a title that says 3.6 kW, 230 V, and about 3–6 m³, with internal control. That price is what the listing shows, and it is not a credible shelf price for a complete stove, so it does not set the bottom of this comparison. There is no star rating and no review text. The bullets say the body is about 51 x 32 x 20.5 cm and 8.5 kg, and that water may be sprinkled on suitable stones, without stating how many kilograms of stone. A plug, a timer, and a maximum temperature are not in the file. If the 3.6 kW figure were real it would still sit above a 13 A socket. Treat the page as an incomplete listing until a normal price and a manual appear.
Pros
The title states one power, 3.6 kW, and a 3–6 m³ band
230 V is in the title
A body size of about 51 x 32 x 20.5 cm is printed
Cons
The printed price is £6.99, which is not a credible stove price
No star rating and no review text
Stone weight, plug, and timer are not stated
Best for: Nobody should plan a cabin around this page while the printed price remains £6.99 and the file has no reviews.
Less suitable: Any buyer using price sort, because this line would look like the cheapest 3.6 kW stove.
The ZXXDSGHUS listing is £291.33 and titles a 4.5 kW dry stove while the bullets also say 3/4.5/6 kW. It describes internal knobs, a 3-hour timer, a 110 °C claim, 20 kg of stones not included, and a wall mount about 18 cm from the ground. There is no review line on the amazon.co.uk file. The technical block says 2.54 x 2.54 x 2.54 cm and 5 kg, which cannot be the stove body, and the image URL is the same as the DHONGGY and WDXQHY pages. A plug is not mentioned. The line that all accessories are included sits next to stones that are not included, so the box contents are not clear.
Pros
A 3-hour timer and a 110 °C claim are written on the page
20 kg of stones is named as not included
Dry use and internal knobs are stated
Cons
Title 4.5 kW conflicts with bullets that list 3/4.5/6 kW
Dimensions of 2.54 cm and a shared image with two other brands
No reviews and no cubic-metre band
Best for: No cabin plan should start here until the seller names one power and a real body size.
Less suitable: Anyone comparing near-£290 stoves by photo, because this image is shared.
The WDXQHY listing is £294.03 and titles an 8 kW dry stove while the bullets also list 3 kW, 6 kW, 8 kW and 9 kW. The rest of the copy matches the shared listing: internal knobs, a 3-hour timer, a 110 °C claim, 20 kg of stones extra, and a wall height of about 18 cm. There is no review line. Dimensions of 2.54 cm and a 5 kg weight are not a stove, and the photo is the same URL as the DHONGGY and ZXXDSGHUS pages. Voltage is written as 220 V/230 V, and a plug is not mentioned. You cannot tell an electrician which current this page is selling. Model 098 is the same model number as the other two copied listings.
Pros
A 3-hour timer and a 20 kg stone note are printed
Dry use and internal knobs are stated
The title parenthesis says 8 kW
Cons
Bullets also list 3 kW, 6 kW and 9 kW
Shared image, 2.54 cm dimensions, and no reviews
No room band and no plug sentence
Best for: No one should order from this page until one power is the only power on it.
Less suitable: Any cabin sized to 8 kW, because the bullets do not confirm that figure.
The title says 8 kW. The bullets list 3 kW, 6 kW, 8 kW and 9 kW. The listing does not resolve that.
Are stones included?
The bullets say 20 kg of stones are required and are not included.
What supply does the title state?
The title says 220 V/230 V. A plug is not mentioned.
How we compared
Eleven amazon.co.uk listings were scored on 19 October 2026 from the stored listings and the review notes already kept for these ASINs. This is not a lab test. A stated kilowatt figure is the listing claim. Approved Document P and BS 7671 Section 703 are safety limits, not score points. The highest score is the top pick. Best value is the lower-priced 6 kW listing that still states one power, a 5–9 m³ band and no plug, after the dent report is already noted. Weights sum to 100.
1
Listing fit
40%
One stated power, a cubic-metre band, a stated voltage, an explicit note that the plug or mains cable is absent, a stone weight, a named control, and a plausible body size. A kilowatt range, a 2.54 cm dimension, or a shared product image loses points.
2
Amazon evidence
25%
Star rating and review count on amazon.co.uk. Eight reviews is still a thin sample, so this block cannot reach the full 25. A listing with no rating line scores low. Written reviews that were not stored with the listing are not treated as extra evidence.
3
Review outcome
20%
A UK review that describes heat and a working timer scores higher than a listing with no review text. Damage on arrival and a missing manual are deductions.
4
Value
15%
Shelf price in GBP against a page an electrician could start from. The lowest printed price does not win this block. £6.99 is not treated as a real price for a complete 3.6 kW stove.

230V sauna heater buying guide
Put room volume, the supply, one stated power, the control, the stones and the quality of the listing ahead of best-seller rank. Advertised complete stoves on this page run from about £123.49 to about £1,300. The printed £6.99 line is not that floor. Home cabin owners who can add a dedicated circuit are the core reader for a 6 kW wall stove. A flat with only a 13 A socket is outside this set. This is not a lab test.
What is a 230V sauna heater?
A 230V sauna heater in this comparison is a wall stove for a home cabin: a metal body, heating elements, a space for stones, and a control for time or temperature. It is not a facial steamer and not a sauna blanket, even when those products sit on the same amazon.co.uk shelf. UK mains are nominally 230 V. A 13 A plug is about 2,990 W, and Which? puts about 3,000 W on one socket.
Best for
A home cabin where you can add a dedicated circuit for a 6 kW wall stove
A larger cabin in a stated 9–15 m³ band if you accept the HUUM listing on its own
Not ideal for
A flat with only a 13 A socket
A first order from a listing whose power or body size is not settled
Mistakes to avoid
1
Trusting a kilowatt range
A title that says 3–6 kW, or that pairs 4.5 kW with 3/4.5/6 kW in the bullets, does not tell you the current. The WDXQHY page says 8 kW in the title and also lists 3, 6 and 9 kW. If the variant is unclear, stop before you ask for a circuit.
2
Assuming a UK plug is in the box
Both Mxmoonant listings say there is no plug. The HUUM listing excludes the mains cable. A 13 A socket is about 2,990 W, and every stated kilowatt figure in this set is above that. A flat that only has a 13 A socket cannot run these stoves.
3
Copying a mounting height
One listing says about 18 cm from the ground and another says about 10 cm. That height belongs to that page, not to the next stove. The word hotel in a title is not a commercial rating, and a three-hour timer is not a commercial timetable.
What to weigh up
Room volume and one power
High
Start with the cabin, not the kilowatt claim. Harvia's published average is about 1 kW per cubic metre of a well-insulated room, plus 1.2 m³ of equivalent volume for each square metre of glass, stone, or a similar surface. Other UK guides use a different glass factor, so the manual for the stove you buy outranks a general average. Avoid the extreme ends of a stated band.
On these amazon.co.uk pages the usable bands are narrow. Both Mxmoonant listings state 5–9 m³ for 6 kW.
Supply, stones and the listing
High
UK mains are nominally 230 V. A 13 A plug is about 2,990 W. SaunaShop's illustration is about 26 A at 6 kW and 35 A at 8 kW. That is not a cable size. The cable and the breaker stay with the electrician. Both Mxmoonant listings say the plug is not included and name a licensed electrician. They also print single-phase and three-phase figures, so the links are an electrician's job. The HUUM bullets exclude the main power cable and say 230 V Europe standard, not a BS 1363 plug.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
🏠
Home cabin, 5–9 m³
The Mxmoonant WS-37-WJY is the top pick at about £297 if you can add a dedicated circuit and you want the digital timer described on the listing. It states 6 kW, 5–9 m³ and no plug, with 4.4 from eight reviews. Skip it if the cabin is outside that band or you only have a 13 A socket.
The Mxmoonant WS-15-WJY is best value at about £269 for the same 6 kW and 5–9 m³ band. UK reviews describe a quick heat-up, and one owner fitted it in under 20 minutes because the rocks were already there. A large dent on arrival is in the UK reviews, and stones are still extra if you do not have them.
The HUUM Hive listing at about £1,300 states 9 kW, 9–15 m³ and a Uku 3 app control, with stones and the mains cable excluded. There is no amazon.co.uk review line. A cheaper 9 kW title is not the same product: the DHONGGY page has no room band and a body size that is not a stove.
The top pick is the Mxmoonant WS-37-WJY at about £297. It has the highest listing score here: one 6 kW figure, a stated 5–9 m³ band, no plug, and 4.4 from eight amazon.co.uk reviews. Eight reviews is a thin sample. Best value is the Mxmoonant WS-15-WJY at about £269, with the same power and room band and a UK report of a dented casing. The score uses the stored listings. It is not a lab test.
How much does a 230V sauna heater cost?
On these amazon.co.uk listings from 19 October 2026, advertised complete stoves run from the Alvinlite at about £123.49 to the HUUM Hive at about £1,300. The two documented 6 kW Mxmoonant listings are about £269 and about £297. Other pages sit near £281 to £298. A generic 3.6 kW line prints £6.99, which is not a credible price for a complete stove and does not set the bottom of the range.
Can a 13 A socket run these sauna heaters?
A 13 A plug is about 2,990 W, and Which? puts about 3,000 W on one socket. Every heater in this set that states a kilowatt figure is above that. SaunaShop's illustration is about 26 A at 6 kW and 35 A at 8 kW, and that is not a cable size. A flat with only a 13 A socket cannot run these heaters. In England a new circuit is notifiable under Approved Document P.
How do you match kilowatts to the cabin?
Harvia's published average is about 1 kW per cubic metre of well-insulated room, plus 1.2 m³ of equivalent volume per square metre of glass, stone, or similar. Other UK guides use a different glass factor. Use the manual for the stove you buy, and avoid the ends of its stated band. Both Mxmoonant listings state 5–9 m³ for 6 kW. The HUUM listing states 9–15 m³ for 9 kW. A kilowatt range is not a room match.
Does Part P apply to a home sauna heater?
In England, Approved Document P makes a new circuit notifiable, and a room with a sauna heater is a special location. The IET's Part P notes cover England and Wales. Scotland and Northern Ireland have their own building rules. BS 7671 Section 703 sets zone 1 as the heater out to 0.5 m, and only the heater and its own equipment belong there. Socket-outlets are not installed in that room. The electrician and the manual decide the protective device.
Are the sauna stones included?
Where a listing mentions stones, they are extra. The dearer Mxmoonant asks for 18–20 kg, the cheaper Mxmoonant for 14–18 kg, and several other pages for 20 kg. The generic external-control page says 14–20 kg, sold separately. The HUUM bullets exclude stones and the main power cable. The generic 3.6 kW page mentions water on stones and states no weight. Harvia stone manuals cap a pour at about 0.2 litres.
Why do some listings near £290 look the same?
The ZXXDSGHUS, DHONGGY and WDXQHY pages share one photo, model number 098, a 5 kg weight and dimensions of 2.54 cm, which cannot be a stove body. The stored prices are about £291.33, £298.17 and £294.03. DHONGGY is the page whose title and bullets both say 9 kW, and it still has no room band and no reviews. A shared photo is not three stoves, and it is not the HUUM listing.
Our verdict
The top pick is the Mxmoonant WS-37-WJY at about £297. It has the highest listing score in this set: one 6 kW figure, a stated 5–9 m³ band, no plug, and 4.4 from eight reviews, with one UK text that describes a timer switching off. Best value is the Mxmoonant WS-15-WJY at about £269, the same power and room band, with a dented casing already in the reviews. For a stated 9–15 m³ cabin, the HUUM listing at about £1,300 is the page that names one power and a room band. Skip any title that prints a kilowatt range, and do not treat £6.99 as the price of a complete stove.
Best overall
Mxmoonant 6 kW digital sauna heater
Highest listing score: one 6 kW figure, a 5–9 m³ band, no plug, and 4.4 from eight reviews.
