Thermowood Barrel Sauna

S 210 barrel sauna: 12 m³ sauna room, long benches and electric or wood-fired heater

The Bloomcabin S 210 uses almost all of its compact exterior dimensions of approx. 211 × 210 × 222 cm for the heated cabin. It has around 195 cm of internal height, an approx. 180 × 198 cm bench area and roughly 12 m³ of interior volume, leaving ample room to sit and move. With no anteroom, it suits sites where cabin space matters more than an integrated changing or storage area. Beyond its footprint, allow a dry, easy-to-walk area directly outside the door.

See the Bloomcabin sauna range for other designs.

S 210 dimensions, layout and heating options

When weighing up models, consider exterior size, usable bench area, internal height, anteroom and heater type as one set. The S 210 pairs a compact barrel shape with a cabin that loses no length to a secondary room. On site, allow beyond the outline for assembly, maintenance, door operation and the needs of your selected heater.

For regular sauna sessions in your own garden

Regular sauna use depends on the space outside as much as the cabin. Provide a short, secure path from the house, somewhere fixed for dry textiles, and convenient places to rest and cool down between rounds. As the S 210 has no anteroom, each of these functions must be arranged externally.

Comfort depends on free movement in the cabin as well as bench area. Every regular user should be able to reach and leave their place without having to squeeze past another person. Consider not only seating positions, but also getting up, throwing water on the stones and walking to the door.

If several guests often use the sauna at once, or a sheltered changing room is needed, compare other models. The relevant figure is not an occasional maximum occupancy, but the number of people who should normally bathe together comfortably. Also allow for rest breaks: more users require more seating outside the S 210.

Natural barrel styling for garden, deck or holiday home

The S 210 is made from FSC®-certified Thermowood. Heat treatment reduces moisture absorption and improves dimensional stability, but the timber remains a natural material affected by moisture, sunlight and temperature changes. Minor shifts in colour and surface appearance are normal. For cleaning or exterior care, use only products expressly suited to that task and to thermally treated timber.

The warm timber colour and round profile complement planted gardens, timber decks and holiday homes, but looks should not decide the location alone. Splashing, dense planting, continual shade and an inaccessible rear side complicate cleaning and inspection. Allow clearance from vegetation and nearby structures so the timber, roof cover and barrel bands remain reachable.

Sunlight can alter the timber colour over time. An appropriate exterior treatment may help retain the original tone for longer. Before the first treatment, decide whether you want to accept this natural colour change or preserve the initial timber shade. Follow the care product instructions and test it first in an inconspicuous area.

Electric or wood-fired heater: two different sauna experiences

Electric heating is convenient for spontaneous or regular sessions and removes the need to prepare or store firewood or clear ash. Its connection must be professionally installed for the selected heater. Before ordering, ask a licensed electrician to plan the cable route, circuit protection, controls and connection for the intended location.

With a wood-fired heater, lighting and tending the fire becomes part of the experience, bringing flame and the smell of timber but also extra preparation. Store firewood safely and dry, supervise the heater while operating, and dispose of ash only after it has cooled. Consider flue routing and future inspection access when selecting the site.

For the wood-fired version, account for the chimney, heat protection, safety clearances and local requirements for solid-fuel appliances. Before ordering either heating type, confirm which parts belong to the selected configuration. Choose not only for the atmosphere you want, but also for the building conditions and day-to-day work involved. The selected heater documentation, local requirements and professional planning of connections or flue routing are decisive.

A level, load-bearing base for the S 210

The sauna needs a level surface with lasting load-bearing capacity. The base must support the timber structure as well as the heater, sauna stones and users. Uneven settlement can affect the barrel shape, door operation and any connections. Seek professional assessment where ground conditions, an existing foundation or the capacity of a deck are not clearly known.

For an existing deck, inspect the entire structure, especially if it is raised, older or timber-built. It is not enough to assess the visible boards; the substructure, supports and load-bearing connections matter too. Before assembly, also establish how components can be moved to the intended location without damaging railings, eaves or other parts of the building.

Rainwater or cleaning water must not remain beneath the sauna. The site should direct water away in a controlled manner while allowing adequate airflow underneath. Avoid tight cladding, added fill or vegetation that traps moisture and blocks inspection of the substructure.

S 210 or N 210: large sauna room or separate anteroom?

The N 210 has a separate anteroom within a broadly similar form. This sheltered intermediate space makes moving between outdoors and the heated cabin easier, but uses part of the available length. The comparison is therefore less about exterior shape than which use should take priority within the particular model size.

Almost the entire length of the S 210 is reserved for the sauna room and broad bench area. This layout better suits people who prioritise comfortable seating and room to move. Omitting the anteroom is intentional: changing, storing belongings and moving between shelter and the sauna must all be managed outside the barrel.

Decide where the anteroom’s functions could go. At the site, identify sheltered space outside for shoes, dry textiles and the route to your rest area. If that works, the S 210 gives more length to the cabin. Choose the N 210 instead when changing and storage need to stay within the sauna structure.

Plan the space in front of the sauna as part of the project

A small roofed area can shelter shoes, towels and bathrobes; an existing covered deck or pergola may serve this purpose. Keep the sauna door’s swing and approach entirely clear. Place furniture, baskets and shoe storage beside the entrance rather than in front of it.

An outdoor shower or plunge pool can complement cooling down, but neither is necessary to use the S 210. More important is an easily reached way to cool down outside the cabin. If water installations are planned, include drainage, cleaning and frost-period management in the planning.

Winter evenings and other low-light conditions call for clear, non-glare lighting and a dependable path. Make steps and edges easy to see. Wet loose pavers, smooth timber or unsecured mats may create trip or slip hazards, so assess the approach both after dark and in damp weather.

Clean, dry and inspect benches and Thermowood correctly

After each sauna session, remove wet textiles and visible water from the cabin. Then open the door and designated ventilation paths so residual moisture can escape. Drying time depends on use and weather. Do not close the sauna after a fixed interval; wait until benches, floor and difficult-to-see edge areas have dried sufficiently.

Clean bench surfaces regularly using material-compatible products. Sauna towels protect timber surfaces from direct contact with perspiration. Use little water, and avoid harsh household cleaners or abrasive tools unless they are expressly suitable. Remove all cleaner residue before heating the cabin again. Regular gentle cleaning is less demanding on the material than occasional intensive deep cleaning.

Also inspect barrel bands, joints and roof covering, particularly after severe weather. Look for loose components, unusual gaps, damaged surfaces and places where water stands. Changes found early can be checked before moisture or movement affects further areas. Work on the heater, electrical system or chimney belongs with qualified professionals; follow the applicable manufacturer and operating instructions.

For couples and small households wanting generous bench space

The S 210 works particularly well when one or two people usually use the sauna and broad benches matter. It is for users who prefer to allocate the available space to the heated room rather than an entry zone. Also consider favourite sitting positions, personal spacing and whether every rest break will happen outside.

Small families may also use the cabin if an anteroom is unnecessary. Arrange seating so everyone can sit comfortably and exit in order. Children require direct supervision and may experience heat differently from adults. A calm, controlled routine is essential around the hot heater, sauna stones and water used on them.

For greater internal height or room for four or more people, also examine the HCF barrel-sauna range. Compare stated specifications against normal occupancy, not a rare peak gathering. A larger structure takes more site and circulation space and may change the access, base and heating requirements. The S 210 instead provides broad benches within compact exterior dimensions.

Easy access makes use simpler throughout the year

For year-round use, a dependable route between house and sauna is especially important. As the S 210 has no anteroom, leave no obstacles immediately outside the door. A firm surface, clearly visible edges and suitable lighting make access easier. Leaves and moisture must not obstruct the entrance or door movement.

If a shower, pool or water connection will form part of the sauna area, direct water away from the foundation. Plan pipes and fittings so they remain accessible during seasonal breaks and can be maintained without dismantling sauna parts. This is particularly important where the water installation is exposed to frost periods.

If you add a canopy, position it so ventilation, roof runoff and access to the outer surfaces remain unobstructed. Do not create a pocket where rain can sit between the cover and barrel. Set privacy screens back far enough to inspect and maintain the roof junctions, timber and barrel bands.

Four questions when choosing a model

Do not assess these points in isolation: your desired seating posture determines bench space, the absent anteroom determines where belongings go, and the heating type determines technical preparation. The site can only be assessed sensibly once access for assembly and maintenance is also secured.

Confirm configuration, delivery route and local requirements before purchase

Use the order documents to verify what the chosen configuration includes. The heater, controls, sauna stones, flue parts and protective components vary by version. Before preparatory work starts, compare the order with the assembly documents so required connections and protection can be allowed for early.

Inspect vehicle access, the unloading area and the entire route to the base, noting low branches, eaves, slopes and delicate surfaces. Components need an orderly, clean place to be set down without unnecessarily obstructing public or shared paths.

Requirements for construction, setbacks and electrical work vary by state, territory, council and site; a wood-fired heater also needs checks for the appliance and flue. Before ordering, confirm the approvals and licensed trades required for the address. Boundaries and neighbouring buildings may affect the design. See planning and assembly guidance for further advice.

Allow for safe operation and good maintenance access from the start

Set the entrance direction before assembly, together with the route to the sauna in darkness and poor weather. Privacy can be part of the location, provided regular access remains straightforward. Leave enough clearance around the structure for cleaning, inspections and any repairs. That way, the S 210 can complement the garden while remaining practical to care for later.

Before heating, remove combustible items from around the heater. Operate only the controls intended for the selected equipment and follow its instructions. For wood firing, have the flue, heat protection and clearances checked against the heater documentation and site requirements. After an unusual smell, visible damage or a fault, keep the sauna off until a qualified inspection is completed.

Prepare the sauna for extended periods out of use as well. Clean and dry the cabin completely beforehand; textiles, loose items and care products should not remain inside permanently. Keep ventilation paths clear. Before heating again, inspect the interior, door, heater area and accessible exterior parts for moisture, foreign objects or visible damage.
