Steam & Oak Honka 180 Sauna Cabin — 2–3 Person Compact Garden Sauna
Couldn't load pickup availability
The Honka 180 is the compact one: 2.19 × 2.33 m externally, a mono-pitch roof and a full-height glass door. It is the smallest cabin in the range and the easiest to find room for.
It is also the one we have real photographs of rather than renders — installed on a timber deck in a hillside garden, which is exactly the kind of spot it suits.
Small footprint, proper sauna
At under 2.2 m wide this fits where a barrel or a 4-metre cabin will not — a side return, a corner of a courtyard, a deck already built. The single room is around 7.1 m³, which is a genuinely efficient size: quick to temperature, cheap to run, and comfortable for two or three.
The mono-pitch roof sheds water to the back, so rain does not run off over the door, and the full glass door keeps a small room from feeling enclosed.

Run it on gas — no electrician, no cable across the garden
This is the option almost nobody else offers, and for a lot of gardens it is the one that makes a sauna possible at all.
A FinSteam gas heater runs on a standard propane bottle — the same sort you would use for a patio heater or a barbecue. No armoured cable, no trench across the lawn, no electrician quote you had not budgeted for. If your garden has no power at the far end, this is how you still get a sauna there.
At around 7.1 m³ this is one of the most comfortable fits for gas we sell — the 8.1 kW heater has plenty in hand, so it comes up quickly and holds temperature without working hard.
Pick a gas option above and we fit the flue and commission the heater on installation day. You do not need to arrange anything with anyone.
Which gas option?
| Botnia 81 | Our standard 8.1 kW gas heater. Everything you need to run the sauna. |
| Aurora 81 | The premium version of the same 8.1 kW heater — better finish and detailing. |
And then: safety pack, or without?
|
With safety pack recommended in a room this size |
Adds the Njord heat shield and the Halo guard rail. The heat shield cuts the required clearance to combustible timber from 200 mm to 50 mm. The guard rail stops anyone brushing against the hot stones. |
| Without safety pack | Heater and stone cage only. Suits an install where clearance is generous and the sauna is for your own use. |
Every gas option includes the heater, the Orbis stone cage, and our fitting and commissioning. See the full gas heater range →
Or choose electric or wood-fired above
Electric — a Harvia heater with a full stone load for soft, steady löyly, integrated controls and a 2-year warranty. At 7.1 m³ the 6 kW is ample. Needs a dedicated circuit installed by a qualified electrician; budget £400–£1,200 for a garden supply on top of the heater.
Wood-fired — a Harvia M-series stove. No electrics at all, a real fire, and the traditional way to run a cabin like this. We fit the flue on installation day. If you are in a smoke control area, check the model against DEFRA's exempt appliance register first — see our smoke control area guide.
2-year warranty
Two years on the structure and on the heater, whichever heat source you choose. Covers manufacturing defects and workmanship.
Where to put it
A cabin like this is a building, not a piece of garden furniture, so it is worth thinking about placement before delivery day rather than after.
Orientation. Point the glazing at whatever you actually want to look at — and preferably away from a neighbour's windows. South-facing glass gains useful warmth in winter but can make the room uncomfortably bright on a summer evening; west-facing catches the sunset, which for most people is when a sauna gets used.
Clearance. Leave at least 300 mm behind and to the sides for air to circulate and for you to get round it with a paintbrush. Timber boxed tightly against a fence stays damp, and damp timber is what fails.
Planning permission. Most garden saunas fall under permitted development, but there are exceptions for size, height, position relative to boundaries, and listed or conservation areas. Our planning permission guide covers the detail — worth ten minutes before you order.
Drainage. Ground should fall gently away from the base. Standing water under a timber building will shorten its life regardless of how well it was built.
Which heat source?
| Electric | Set-and-forget, thermostat controlled, no fire to tend. Needs a dedicated circuit and an electrician — usually the largest hidden cost on a garden sauna. |
| Wood-fired | The traditional method and the best heat, but you tend a fire, clear ash, and sweep the flue. Restricted in smoke control areas unless the stove is DEFRA-exempt. |
| Gas (propane) | No cable, no trench, no electrician. Runs off a standard bottle, comes up in under 20 minutes, and works in a power cut. Unrestricted by smoke control rules. |
Our honest steer: if you already have power at the far end of the garden, electric is the least fuss. If you do not, gas usually costs less than running a new supply and gets you there faster. Wood-fired is for people who want the ritual and have somewhere for the smoke to go. Our full comparison goes through the running costs.
Lead time — please ask before you order
Lead times vary with stock and specification — anything from 2 to 12 weeks. Ask us before you commit and we will give you the real date for the exact build you want, not an optimistic one.
Getting it into your garden
One of the easier saunas to site — compact enough that the panels carry through a standard side gate, and light enough at around 650 kg that a well-compacted paved base is fine.
It needs a level, load-bearing, well-draining base — paving slabs on a compacted sub-base or a concrete pad. Our construction service starts at £500, and we apply insulating paste between every panel as we build, which is the single biggest factor in whether a sauna holds its heat properly.
