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.
