Steam & Oak Gas Cube Sauna 1.8m (Electric Option) - Gas — Aurora 81 with safety pack
NEW: First UK cube sauna available with gas heat — Steam & Oak × FinSteam Pick "+ FinSteam Aurora 81 R11S Gas Heater" at checkout and your cube ships with engineered ventilation built for gas + a bundled FinSteam Aurora 81 R11S 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 £4,795 £6,690 Electrician — dedicated circuit + Part P £800–£1,500 £0 Ready to use After wiring is booked + signed off Day of delivery Real total £5,595–£6,295 £6,690 The ~£2,000 gap on the shelf narrows to roughly £400–£1,100 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 — the gas variant doesn't have those. Vent + heater certified together under EU Reg 2016/426. Electric variants ship with the standard vent set for an electric heater. What's in the gas variant package Cube shell + alder benches + 8mm tempered glass. Engineered gas-ready ventilation built in. FinSteam Aurora 81 R11S gas heater — 8.1 kW, AENOR-tested under Reg 2016/426. ODS auto-shutoff + flame monitoring. Includes Orbis 11 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 R11S standalone retail £2,295 — gas variant bundles at £6,690 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 1.8m — pick your heater at checkout The choice (heater options) + FinSteam Aurora 81 R11S 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 isn't available on the 1.8m size — the ~4.5m³ interior is too small for our supplier's stocked wood-fired stove. For wood-fired, see the 2.4m and larger models. The compact 1.8m cube sauna — straight-walled architectural form, full standing height, glass-front door. Trades the rustic barrel look for a clean modern silhouette: square frame, flat-roof aesthetic, more usable bench length than a barrel of the same external footprint. Running cost + warm-up Gas (Aurora R11S): ~£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. See our full running-cost breakdown. Why a cube instead of a barrel Same build quality as the barrel range (44mm Scandinavian spruce, alder benches, 8mm tempered glass), but the cube format gives you full standing headroom throughout, longer usable bench length, and a clean architectural silhouette that pairs with modern garden buildings + contemporary patios. Where the barrel hides in a corner, the cube is a deliberate design statement. Build + finish Walls: 44mm Scandinavian spruce, kiln-dried 14% moisture Benches: Alder, single-level Door + windows: 8mm tempered glass Roof: Bitumen shingles Heater: Choose FinSteam Aurora 81 R11S gas, Harvia 6.8kW or 9kW electric at checkout — or shell-only if you have your own heater What's included Sauna shell, base beams, wooden panels (pre-cut + numbered), stainless steel tension bands, alder benches with backrests, 8mm tempered glass door, ventilation valve + grill (vent type
