Steam & Oak Gas Barrel Sauna 2.4m with Porch (Electric or Wood-Fired)

NEW: First UK barrel sauna available with gas heat — Steam & Oak × FinSteam

Pick "+ FinSteam Aurora 81 R14S Gas Heater" at checkout and your barrel 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) and the heater that powers the FinSteam NOIR Signature packages.

Why gas changes the equation

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.

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 into the cabin: intake ≥350 cm² low next to the heater (drawing fresh air directly from outside), exhaust ≥250 cm² high in the opposite corner (discharged directly to outside). FinSteam explicitly exclude plastic disc / twist valves — the gas variant doesn't ship with those. The vent configuration and the FinSteam heater are certified together under EU Gas Appliance Regulation 2016/426. Pick the electric or wood-fired variant instead and the sauna ships with the appropriate vent set for that heat type — pick the heater at checkout and the build matches.

What's in the gas variant package

• The barrel shell + porch + alder bench + 8mm tempered glass — same build as the electric/wood variants of this model.
• Engineered gas-ready ventilation built in (wooden louvres, FinSteam-spec sizes).
• FinSteam Aurora 81 R14S gas heater — 8.1 kW, EU Type-Examination Certificate, AENOR-tested under Reg 2016/426. ODS oxygen-depletion auto-shutoff + flame monitoring. Configuration includes Orbis 14 stone cage + Halo safety rail + Njord heat shield as standard.
• UK propane regulator + 1.2 m CE-marked gas hose (I3P 37 mbar, 27 mm clip-on for standard Calor 13 kg propane bottles).
• 40 kg pre-washed FinSteam sauna stones, sized for the cage.

The Aurora 81 R14S retails standalone for £2,395 — the gas variant bundles it with the engineered cabin build at a single price (£6,790 inc VAT). Zero warranty returns on the FinSteam heater in the last 12 months. More on the Aurora 81.

What you'll need to source locally

• A standard UK 13 kg Calor propane bottle — bought locally. The included regulator + hose connects to one.
• A Gas Safe registered engineer for the gas connection on a fixed install. Required by UK regulation for fixed gas connections.

Steam & Oak Barrel Sauna 2.4m with Porch — 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. See full 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, no electrical install. Includes chimney pipe + flashing kit. (Wood-fired stove is rated for 6-12m³ saunas.)

The 2.4m barrel extends the entry barrel with a 0.4m covered porch — the small detail that turns a sauna kit into a proper garden building. The porch is where people sit to cool down between löyly throws, change footwear, hang towels. 44mm Scandinavian spruce walls + alder benches + 8mm tempered glass throughout.

Running cost + warm-up (the question buyers ask first)

Configured with the FinSteam Aurora 81 R14S gas heater, running cost is approximately £2.00-£2.50 per 60-90 minute session (around 0.6 kg propane per session at a typical £47 / 13 kg Calor refill). Warm-up: 15-20 minutes from cold to 70-75°C.

Configured with a Harvia 6.8kW electric heater, this sauna runs at £1.75–£2.25 per 90-minute session at the 2026 price cap. Warm-up takes around 30 minutes. Configured with a 9kW Harvia, those numbers move to about £2.00–£2.50 per session. With the Etna 12 wood-burning stove, the running cost moves off the electricity bill entirely — typical hardwood log cost is £2–£4 per session. See our full running-cost breakdown.

The porch advantage

Comparable 4-person UK barrels — our own Rustic Barrel 6ft is the closest at this capacity — don't have an integrated porch. The 0.4m covered space at the door is genuinely useful: somewhere to sit during cool-down without standing on wet grass, to remove boots before stepping inside, or to position a small wood log store next to the wood-fired heater. Practical detail, real quality-of-life difference.
