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.

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.
