Steam generator or sauna stove at 6 kW
Updated: October 2026
Your amazon.co.uk search says 6 kW sauna and returns a £229 steam kit beside a £269 stone stove, both with similar thumbnails and the same kilowatt headline. Steam generator vs sauna stove at 6 kW is not a price contest. It is a room and climate choice. A stone stove dries and heats a cabin toward roughly 75–100°C with stones in a basket; a steam generator feeds a nozzle at about 35–55°C in a sealed, tiled shower. Our [sauna heater 6kW comparison](/hub/steam-baths/sauna-heater-6kw) lists nine kept rows. This page splits them by type so you shop one column only.

Two climates, one kilowatt number
Public leisure guidance in the UK often quotes a sauna at 75–85°C with low humidity, while a steam room sits nearer 40–50°C with high humidity. Eden Hut’s UK explainer uses similar bands. The stoves in our set print up to 110°C, 0–110°C, or 230°F where stated; the generators print 35–55°C consistently. You cannot move a steam generator into a timber cabin and expect löyly, and you cannot hang a wall stove in a tiled shower and expect a safe steam room.
Water on stones from a ladle is a brief humidity spike in an otherwise hot, dry room. Steam from a generator is continuous wet heat in a waterproof box. If your plan is cladding and benches, choose the stove path and read 6 kW sauna heater room size. If your plan is a shower rebuild with a sloped ceiling and a sealed door, choose the generator path and plan plumbing as well as electrics on 6 kW sauna heater installation.
What each machine needs around it
A stone stove mounts on the wall, holds 14–20 kg of stones in many listings here, and expects you to buy those stones separately. It needs a certificated electrical supply with no plug on most rows, and ventilation clearances from the manual. Heat storage is in the stone mass; session length is often set with a timer on the stove or an external controller.
A steam generator sits in a cupboard or adjacent space, connects to a water line, a drain and a steam head in the cubicle, and uses protections such as low water and overheat where the listing states them. CGOLDENWALL’s box list includes a nozzle, probe, LED controller, drain and safety valve. LANYU’s title names a steam head and a waterproof digital controller. None of that replaces a stone basket. It replaces plumbing.
Trades split accordingly: an electrician for both, a plumber for steam feeds and drains. Do not ask one trade to sign off the other’s scope.
How the amazon.co.uk 6 kW set splits
Stone stoves in the kept set: Alvinlite B0CDCCMZ8M; KJUEQ B0HGLJTXBR; JMbpkduHs B0DSFYH7RW; Mxmoonant B0CLXVKGMD and B0DD3HCJS1; UIGJIOG B09NFFZ1PY. Steam generators: LANYU B0H4F2PSZP; CGOLDENWALL B00KB3I224; Hanchen B081DLRWG3.
Stoves quote 5–9 m³ or lack volume on the cheapest row. Generators quote 6 m³ or within 4.2 m³ at 35–55°C. If your cubicle is 4 m³ of tile, Hanchen’s volume line is closer than a 5–9 m³ stove bullet. If your cabin is 7 m³ of insulated timber, a generator’s 6 m³ steam figure is the wrong climate entirely.
Branded UK steam such as Mr Steam’s 6 kW residential units can sit near £2,790 with professional sizing tables. Amazon’s £229–£449 generators are a different channel. Compare inside the generator column only, not against Harvia shop prices for stoves.
Stoves in this set quote timers from built-in panels up to three hours, or 0–180 minutes on the UIGJIOG line, while Hanchen’s steam unit advertises 30 minutes to 12 hours. Neither replaces the other’s climate. Running a generator in a timber shell would be a moisture hazard; running a stove in a sealed shower would overshoot safe temperatures for a wet room.
Health marketing on marketplace listings sometimes mentions weight loss or rheumatism. NHS-linked pregnancy guidance instead warns about overheating in hot environments. If you have heart disease, blood pressure issues, diabetes or pregnancy, ask a clinician before committing to either room type.
When to pick which
Pick a stone stove if you are building or refurbishing a wood-lined sauna cabin, you want high heat with optional water on stones, and your volume sum fits the manual band for 6 kW with margin. Pick a steam generator if you are tiling a shower or steam cubicle, you want 35–55°C wet heat, and you will seal the room and install water and drain paths.
If you are replacing like for like, still read the old plate and breaker. A 6 kW steam unit on the same cable as an old 6 kW stove may not match the protective device or the room type. When in doubt, treat the room you are building as the primary key, not the word sauna in the title.
Common questions
Is a 6 kW steam generator a sauna heater?
It is a steam-room heater at 35–55°C on these listings, not a replacement for a hot stone-stove cabin.
What temperature should I expect from each?
Roughly a 75–100°C class of dry heat for stoves where a temperature is stated, versus 35–55°C wet steam for the generators.
Can I put a steam generator in a wooden cabin?
No. Steam needs a waterproof tiled enclosure. Timber sauna cabins expect dry heat and a stove.
Can I get löyly from a steam nozzle?
Löyly in the Finnish sense comes from water on hot stones in a dry room, not from a shower steam head.
Which kept Amazon listings are which type?
Six stone stoves and three steam generators. See the split in the set above, or the Type column on the main comparison.
Why is a branded steam generator thousands of pounds when Amazon shows £229?
Different channel, sizing support and install expectations. Compare within the channel you will actually buy.
Who installs each one?
An electrician for both. A plumber as well for steam water paths and the drain.
