Steam & Oak Barrel Sauna 3m with Anteroom and Canopy

Create a dedicated space for relaxation, recovery and time outdoors with the Steam & Oak 3m Barrel Sauna with Anteroom and Canopy. Combining traditional Scandinavian spruce construction with a sheltered entrance and separate changing area, this spacious garden sauna is designed for shared sessions and year-round outdoor use.

Choose between gas, electric or wood-fired heating at checkout, or select the shell-only option if you already have a suitable heater. The extended canopy provides extra shelter around the entrance, making it a practical choice for exposed gardens and changeable weather.

Choose your heater

• FinSteam Aurora 81 R14S Gas Heater – An electricity-free heating option with engineered ventilation, safety components, regulator, gas hose and sauna stones included.
• Harvia PC70 6.8kW Electric Heater – A practical electric option for regular sauna sessions, requiring a suitable dedicated electrical supply.

Why choose gas heating?

The FinSteam Aurora 81 R14S provides an alternative to conventional electric and wood-fired heating. Running on propane, it does not require an electrical connection to operate, making it an option to consider for gardens where installing a dedicated sauna circuit may be difficult.

Warm-up times and running costs are estimates. Actual results depend on outdoor temperature, starting temperature, session length, energy prices and the selected heater.

What's included with the gas configuration?

• Barrel sauna shell, canopy and anteroom – With alder benches and 8mm tempered glass.
• Aurora 81 R14S gas heater – 8.1kW output, with flame monitoring and an oxygen-depletion safety shut-off.
• Orbis 14 stone cage – Designed to hold the sauna stones.
• Halo safety rail – A protective rail around the heater.
• Njord heat shield – Included with the heater package.
• 40kg of pre-washed sauna stones.
• UK propane regulator and 1.2m CE-marked gas hose.
• Engineered gas-ready ventilation – Wooden louvre vents built into the cabin.

The gas ventilation configuration includes a low-level fresh-air intake of at least 350cm² beside the heater and a high-level exhaust of at least 250cm² in the opposite corner. Both are designed to connect directly to the outside.

The gas-heated configuration is priced at £8,090 including VAT. The Aurora 81 R14S gas heater is also available separately.

Gas heating costs and setup

With the Aurora 81 R14S gas heater, a typical session costs approximately £1.50–£2.00, with a warm-up time of around 15–20 minutes. Actual costs depend on propane prices, usage and operating conditions.

You'll need to source a standard UK 13kg Calor propane bottle locally. A Gas Safe registered engineer is required for a fixed gas connection. Check the heater's installation instructions and applicable safety requirements before use.

Gas vs electric: comparing the total cost

The purchase price is only part of the cost of setting up an outdoor sauna. An electric heater needs a suitable dedicated circuit, installed by a qualified electrician. Gas heating avoids the need for a dedicated electrical circuit to operate the heater, although installation costs may still apply depending on your setup.

These are indicative comparison figures. Electrical installation costs depend on your property and the work required. Any applicable gas installation costs are additional.

Running costs for each heating option

• Gas – Aurora 81 R14S: Approximately £1.50–£2.00 per session, with a typical warm-up of 15–20 minutes.
• Electric – Harvia PC70 6.8kW: Approximately £1.75–£2.25 per 90-minute session, with a typical warm-up of around 30 minutes.
• Electric – Harvia PC90 9kW: Approximately £2.00–£2.50 per session.
• Wood-fired – Etna 12: Approximately £2–£4 per session for hardwood logs.

These estimates vary with energy prices, session length and how frequently you use the sauna.

A canopy and anteroom for a more comfortable sauna ritual

The extended canopy roof projects beyond the entrance, creating a more sheltered transition between the garden and the sauna. It's particularly useful when the weather is changeable, providing extra cover as you move between the outdoors, the changing room and the heated cabin.

The enclosed 0.75m anteroom gives you a separate place to change out of outdoor clothing, hang dressing gowns and keep sauna essentials close at hand. Together, the canopy and anteroom help turn the sauna into a more complete outdoor wellness space.

Choose the canopy version if you value extra shelter around the entrance, especially in exposed or coastal gardens. If a more compact roofline is a priority, consider the standard 3m Barrel Sauna with Anteroom.

Built from solid Scandinavian spruce

The sauna is constructed from solid 44mm Scandinavian spruce, kiln-dried to a stated moisture content of 14%. The thick timber walls form the main structure rather than simply covering a separate hidden frame.

Slow-grown spruce develops tight growth rings in colder climates, giving the timber a dense, substantial feel. The solid walls provide a robust structure and help create the warm, enclosed atmosphere that makes a sauna such a rewarding place to unwind.

The natural timber can also be finished with oil or colour to suit your garden. If you'd like to explore alternative timber options, read our comparison of thermowood and slow-grown spruce.
