NEW: First UK cube sauna available with gas heat β Steam & Oak Γ FinSteam
Pick "+ FinSteam Aurora 81 R14S Gas Heater" at checkout and your cube ships with engineered ventilation built for gas + a bundled FinSteam Aurora 81 R14S gas heater package β ready to light on a UK propane bottle the day it lands. Steam & Oak is the only UK retailer offering this. No electrician, no chimney, no fire to tend. Hot in 15 minutes, turn a dial. The Aurora 81 is the only CE-marked electricity-free sauna gas heater on the European market (FinSteam's stated claim).

The real cost to your first sauna β gas vs electric
An electric sauna's shelf price isn't the price to your first lΓΆyly. A 6.8β9 kW electric heater needs its own dedicated circuit, wired by a qualified electrician and signed off under Part P β typically Β£800βΒ£1,500, plus the wait to get one booked. The FinSteam gas heater connects to a UK propane bottle outside, like a patio heater: no dedicated circuit, no electrician for portable use, and it's hot on the day it arrives.
| Electric (from) | Gas (FinSteam) | |
|---|---|---|
| Cabin + heater | Β£5,295 | Β£7,290 |
| Electrician β dedicated circuit + Part P | Β£800βΒ£1,500 | Β£0 |
| Ready to use | After wiring is booked + signed off | Day of delivery |
| Real total | Β£6,095βΒ£6,795 | Β£7,290 |
The ~Β£2,000 gap on the shelf narrows to roughly Β£500βΒ£1,200 once the electrician is in the sum β and the gas sauna doesn't wait on a sparky's diary. (Portable use needs no Gas Safe engineer; a fixed install does. A standard UK 13 kg Calor propane bottle runs the heater for a dozen-plus sessions.)
What "gas-ready" means β engineered vents built into the cabin
The gas variant ships with wooden louvre vents at the FinSteam-specified sizes built in: intake β₯350 cmΒ² low next to the heater (fresh air from outside), exhaust β₯250 cmΒ² high in the opposite corner (discharged to outside). FinSteam exclude plastic disc / twist valves. Vent + heater certified together under EU Reg 2016/426. Electric/wood-fired variants ship with the appropriate vent set for that heat type.
What's in the gas variant package
- Cube shell + porch + alder benches + 8mm tempered glass.
- Engineered gas-ready ventilation built in.
- FinSteam Aurora 81 R14S gas heater β 8.1 kW, AENOR-tested under Reg 2016/426. ODS auto-shutoff + flame monitoring. Includes Orbis 14 stone cage + Halo safety rail + Njord heat shield as standard.
- UK propane regulator + 1.2 m CE-marked gas hose.
- 40 kg pre-washed FinSteam sauna stones.
Aurora R14S standalone retail Β£2,395 β gas variant bundles at Β£7,290 inc VAT. More on the Aurora 81.
What you'll need to source locally
- Standard UK 13 kg Calor propane bottle.
- Gas Safe registered engineer for the gas connection on a fixed install.
Steam & Oak Cube Sauna 2.4m with Porch β pick your heater at checkout
Steam & Oak β one of the very few UK sauna brands that lets you choose gas, wood-fired OR electric on the same listing. Pick at checkout.
The choice (heater options)
- β + FinSteam Aurora 81 R14S Gas Heater (UK first) β the new gas option. Details above.
- Shell only β buy the cabin, source your own heater.
- + Electric Harvia PC70 6.8kW β sized for the interior, single-phase ~25A circuit.
- + Electric Harvia PC90 9kW β for faster heat-up.
- + Wood-Fired Etna 12 stove + flue kit β traditional log-fired ritual.
The 2.4m cube extends the entry cube format to a 2.35m main room + 0.4m covered porch β the standard 4-6 person cube with practical covered transition space at the door. Same 44mm Scandinavian spruce walls + alder benches + 8mm tempered glass as the rest of the range, scaled for shared sessions.
Running cost + warm-up
Gas (Aurora R14S): ~Β£1.50-Β£2.00 per session, 15-20 min heat-up. Electric (Harvia 6.8kW): Β£1.75-Β£2.25 per 90-min session, 30 min heat-up. Electric 9kW: Β£2.00-Β£2.50 per session. Wood (Etna 12): Β£2-Β£4 hardwood logs. See our full running-cost breakdown.
Porch + clean architectural form
The 0.4m porch on the 2.4m cube does what the 2.4m barrel's porch does β a covered transition space at the door for boots, towels, cooling down. Paired with the cube format's straight-wall architectural silhouette, this is the standard 4-6 person outdoor sauna for buyers who want modern garden-building aesthetics rather than rustic barrel curves.
