Steam & Oak Gas Cube Sauna 3.4m Premium L-Bench (Electric or Wood-Fired) - Shell only
NEW: First UK cube sauna available with gas heat — Steam & Oak × FinSteam Pick "+ FinSteam Aurora 81 R14S Gas Heater" at checkout and your flagship cube ships with engineered ventilation built for gas + a bundled FinSteam Aurora 81 R14S gas heater package — 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). Why gas changes the equation Gas (new) Wood Electric Heat-up time ~15 min 30-45 min 30-60 min Electrician / wiring None None 32A circuit (£1-2k) Chimney / flue None Required None Smoke, ash, soot None Every session None Off-grid / power-cut Yes Yes No Running cost / session ~£1.50-2.00 £2-4 logs £1.75-3.25 Safety EU-cert, auto O₂ shut-off Open flame Electrical The real cost to your first sauna — gas vs electric An electric sauna's shelf price isn't the price to your first löyly. A 6.8–9 kW electric heater needs its own dedicated circuit, wired by a qualified electrician and signed off under Part P — typically £800–£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 £7,295 £9,290 Electrician — dedicated circuit + Part P £800–£1,500 £0 Ready to use After wiring is booked + signed off Day of delivery Real total £8,095–£8,795 £9,290 The ~£2,000 gap on the shelf narrows to roughly £500–£1,200 once the electrician is in the sum — 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 — engineered vents built into the cabin The gas variant ships with wooden louvre vents at the FinSteam-specified sizes built in: intake ≥350 cm² low next to the heater (fresh air from outside), exhaust ≥250 cm² 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 Premium cube shell + porch + anteroom + L-shape two-level alder bench + 8mm tempered glass. Engineered gas-ready ventilation built in. FinSteam Aurora 81 R14S gas heater — 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 £2,395 — gas variant bundles at £9,290 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 3.4m Premium L-Bench — pick your heater at checkout Steam & Oak — 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) + FinSteam Aurora 81 R14S Gas Heater (UK first) — the new gas option. Details above. Shell only — buy the cabin, source your own heater. + Electric Harvia PC70 6.8kW — sized for the interior, single-phase ~25A circuit. + Electric Harvia PC90 9kW — for faster heat-up. + Wood-Fired Etna 12 stove + flue kit — traditional log-fired ritual. Our flagship cube — 3.35m external + 0.4m porch + 0.75m enclosed anteroom + L-shaped two-level alder benches. The premium 6-person UK outdoor sauna with everything dialled in: standing-height cube format, proper anteroom for changing + cool-down, two-level corner bench layout, 44mm walls + 8mm glass + 24-month warranty + heater of your choice. Running cost + warm-up Gas (Aurora R14S): ~£1.50-£2.00 per session, 15-20 min heat-up. Electric (Harvia 6.8kW): £1.75-£2.25 per 90-min session, 30 min heat-up. Electric 9kW: £2.00-£2.50 per session. Wood (Etna 12): £2-£4 hardwood logs. See our full running-cost breakdown. The L-shaped two-level bench is the differentiator Two-level benches matter for shared sessions — different users have different heat tolerance, and the lower bench (cooler + closer to floor airflow) is genuinely usable for kids, older users, or anyone who finds 90°C bench-top intense. The L-shape adds corner seating that lets people face each other during conversation rather than sit shoulder-to-shoulder. Against the typical 6-person cube at this price point, this cabin ships with L-shaped two-level alder benches plus a 0.75m enclosed anteroom, where most rivals offer single-level benches and no anteroom. Build + finish Walls: 44mm Scandinavian spruce, kiln-dried 14% moisture Benches: Alder, two-level
