Thermowood Barrel Sauna

HC 225: thermowood barrel sauna for two to three people, suitable for use with a wood-fired stove

The Bloomcabin HC 225 is designed for couples, small families and friends wanting more room than a mini barrel sauna while deliberately choosing no separate changing room. At approximately 229 cm long, 194 cm wide and 204 cm high, it remains compact. Internal height is about 175 cm. As the entire exterior length serves the sauna room, there is more bench length and legroom.

Capacity, dimensions and heating at a glance

Consider these features together, since capacity, internal height and heating type shape daily use just as much as the external dimensions.

FSC®-certified thermowood for a classic barrel-sauna look

The HC 225 is made from thermally treated wood. Heat treatment reduces moisture absorption and helps the wood remain more dimensionally stable than untreated timber.

Its visible grain and warm timber tone suit natural plots, holiday homes and wooden terraces especially well. Beside a modern home, the rounded form can also create a deliberate contrast.

Even thermally treated wood responds to moisture and temperature. Barrel bands, fixings, the door and seals should therefore be checked regularly.

Traditional sauna bathing with a wood-fired stove

The HC 225 is suitable for a wood-fired sauna stove. Fire, crackling wood and regulation through fuel and airflow make heating up a considered part of the sauna evening.

A wood-fired stove needs more preparation than an electric solution. Before installation, obtain project-specific advice on the flue, heat protection, clearances, fire safety and any Planning Authority requirements. Check the planned site with competent professionals.

Match the planned stove solution early to the exact HC 225 configuration and site. The relevant quotation and the installation and safety instructions for the selected components remain decisive.

Plan the outdoor area to replace the changing room

Because the HC 225 has no changing room, towels, bathrobes, shoes and drinks need a dry, accessible place outside the cabin. A covered terrace, garden room or other sheltered area can work well. Keep the sauna entrance clear so stored items and loose textiles cannot obstruct the door. Nearby seating also makes changing easier without using sauna space.

The base must be level, load-bearing and arranged for reliable drainage after rain. Individual bearing points must not sink or distort the barrel structure. Check the construction below the visible surface too. Assess an existing terrace for condition, strength and drainage; for a new site, the sub-base must suit both sauna and plot. Water must not collect beneath timber parts or around the entrance.

Plan the sauna, stove and flue together when choosing the location. The chimney position affects clearances from buildings, plants and other garden features, while access for inspection and cleaning must remain open. Consult the appropriate professionals and authorities before assembly. Later alterations can be difficult where branches, roof overhangs or site conditions obstruct the planned flue route.

Who the HC 225 suits especially well

This model is a particularly good fit where two people usually sauna, a third joins occasionally, and a wood-fired stove is an intentional part of the experience.

HC 225 or HCF 225: compact seated sauna or more headroom?

The HC 225 is narrower and lower. It is aimed at buyers seeking a compact seated sauna for two to three people.

The HCF 225 is approximately 229 cm wide and 238 cm high. With around 210 cm of internal height, it offers substantially more vertical space and accommodates up to four people.

Choose the HC 225 if compact external dimensions are the priority. If greater headroom, longer benches and a more open feel matter more, shortlist the HCF 225.

Mark out the footprint in your garden before buying

Mark the HC 225 external dimensions at the proposed location. Include the door area, working space needed for assembly and required clearances. This shows whether access remains comfortable and whether there is enough room around the sauna for care and work on the stove and chimney. The footprint alone does not show the garden space required.

Use the documents for the exact version to check the bench layout. Consider which seats will be used most often and whether available bench length suits your height and preferred position. External dimensions alone cannot answer this comfort question.

Also plan the route between house, storage area and sauna. Wet shoes, clothing and personal items do not belong on sauna benches. A dry storage point and clean access route ensure the cabin can be used entirely for sauna bathing.

Plan location, access and cooling-off together

A well-chosen location shortens the walk from the house and simplifies the whole sauna routine. The route should be visible in darkness, safe to walk and free from trip hazards. Check that doors and garden gates are easy to pass and that the route remains usable when wet or cool. Lighting should cover the entrance and path without unnecessarily dazzling the relaxation area. Outdoor electrical work requires a REWS-authorised professional with appropriate scope.

An accessible outdoor area is enough for cooling down. Plan a shower, plunge pool or swimming pool only where space and intended use support it. Consider water supply, drainage, cleaning and any seasonal shutdown. Run-off must not remain at the sauna base or make the path slippery. You can reserve movement space now for a later addition.

As relaxation takes place outside the HC 225 cabin, sheltered nearby seating is useful. Arrange furniture, screening and plants so access, stove maintenance and safety areas remain clear. Maintain required clearances from hot equipment and the flue.

Inspect thermowood regularly and clean gently

UV light, rain and temperature changes can alter thermowood colour and surface over time; this is not automatically damage. What matters is that water does not remain in isolated areas and dirt does not obstruct drainage. Keep the area around the barrel sauna clear so air can circulate and timber can dry after rain.

Check door operation, seals, visible screw connections and barrel bands regularly. Do not adjust components as a precaution or without a clear reason. Check a sticking door, conspicuous gaps or loose connections against the assembly and care instructions before intensive use resumes.

Clean the interior with gentle methods and products suitable for sauna timber. Use as little water as possible and let all surfaces dry openly afterwards. Harsh cleaners, abrasive tools and pressure washers can roughen wood fibres or force moisture into joints. The same applies outside: clean as dry and gently as possible. Care products must suit thermally treated timber and the intended application.

Clarify contents, transport route and local requirements early

Check your chosen configuration carefully before ordering. Suitability for a wood-fired stove does not automatically mean that the stove, sauna stones, chimney parts, heat shields and all assembly accessories are included. The stated contents of the specific offer are decisive. Clarify what is planned for assembly, stove installation and flue work, and which tasks require suitably qualified professionals.

Assess the complete transport route from the intended unloading point to the prepared site. Narrow gates, projecting walls, stairs, steep slopes, soft ground, low branches and tight turns can complicate moving large components. Check height restrictions and turning areas as well as available width. Keep access clear on delivery day and confirm in advance which lifting or transport aids are required for the chosen delivery method.

Also clarify site-specific requirements for development, boundaries, the stove and, where applicable, electrical installations. In Malta, have a perit assess the Planning Authority classification for the actual plot, footprint, height, enclosure and site restrictions. Obtain reliable advice before fixing the base and chimney position. Find further guidance under Useful information.

Assess seating comfort in the exact version

At an internal height of approximately 175 cm, personal comfort depends not only on height but also on how you move. Check whether regular users can enter comfortably, sit on the bench and stand up again. Someone wanting to change inside or move upright frequently has different requirements from someone who mainly sits.

Include the actual bench layout in your assessment. Where possible, compare stated dimensions with a familiar bench and consider how much space knees and legs need in your preferred position. This gives a more realistic indication of whether the chosen version suits your usual use.

If more upright freedom of movement is important, compare the HCF 225, with an internal height of around 210 cm.

Does a wood-fired stove suit your routine?

Before every sauna evening, firewood, kindling and required accessories should be ready. Heating needs active supervision, while residual heat and ash need proper handling afterwards. Consider whether this recurring routine fits your lifestyle rather than deciding solely on the heat source you prefer.

Operation also includes tasks beyond the sauna session: store firewood dry, keep the stove area clean, leave the chimney accessible and replenish consumables in good time. Storage must be outside the hot cabin and must not restrict safety, access or working areas. Including this in garden planning avoids improvised solutions later.

Where several people use the sauna, agree who operates the stove and who ventilates, cleans and secures it afterwards. Children and inexperienced guests need appropriate supervision and clear guidance about hot surfaces. The operating instructions and requirements of installed components remain decisive for operation and safety.

Good preparation protects components and simplifies final checks

Before assembly starts, the sub-base, access route and storage area should be fully prepared. Delivered timber parts need a clean, dry place protected from damage until installation. Check delivery against the relevant documents and report visible discrepancies before fitting components. Open packaging carefully so unsuitable tools cannot damage timber surfaces.

Follow the model-specific assembly instructions and do not alter load-bearing or heat-protection components yourself. The rounded barrel structure must be aligned evenly; an unsuitable base cannot be corrected by tightening afterwards. Doors and fittings can only be assessed reliably once the sauna stands correctly. For the stove and chimney, follow the component instructions and project-specific professional advice; any electrical connections require a REWS-authorised professional with appropriate scope. Complete visual and functional checks before the first heating.

Keep assembly, operating and care documents with the details of the installed stove and chimney. This helps with future cleaning, spare-part queries and discussions with professionals. Photos of concealed cable routes or connection details may also help. A documented handover is especially useful where assembly and technical installation are completed by different contractors.

Ventilate fully and allow drying after every sauna session

Heat and moisture remain in the cabin after use. Use the intended ventilation provisions in line with product and stove instructions, and allow timber surfaces sufficient time to dry. Remove water containers, wet textiles and loose sauna items. Check benches and floor for moisture or dirt before closing the door for an extended period.

Before long breaks in use, the interior should be clean and dry. Check that ventilation openings remain clear and that no textiles or organic residues are left behind. Do not cover the timber sauna airtight, because trapped moisture escapes less readily. Any additional weather protection must suit the construction and permit necessary ventilation.

Do not conceal odours, dark damp patches or unusually slow drying with fragrances or surface treatments. First check whether rain is entering, water is spilled during sauna use or air exchange is obstructed. Seek professional advice if the cause cannot be identified clearly.

Rainwater must drain freely on the outside

The rounded barrel shape defines the HC 225 appearance. Keep the immediate perimeter free of soil, leaves and objects that retain moisture against timber or hinder inspection. After heavy rain, check that the prepared drainage still works. Later-added beds, edges or paving must not alter the water route.

Overhanging branches, constantly spraying irrigation and dense planting can slow drying and obstruct maintenance access. Adequate space around the sauna makes exterior timber, barrel bands and connections easier to inspect. Plants must not reach hot components or the flue. Before adding roofs or cladding, confirm they are technically suitable and compatible with the intended construction.

Keep the entrance and walking route clear and safe so the door can operate freely. Do not use cleaning tools or products that could damage timber, fittings or adjacent surfaces. Before heating, briefly check that ventilation areas are open, access is clear and the chimney shows no visible irregularities. Remove combustible items from required safety areas. This visual check does not replace regular professional maintenance.

Clear responsibilities matter especially at holiday homes

At a privately used holiday home, the HC 225 is especially practical where the building already provides space for changing and dry towels. For longer absences, decide who checks the interior, door, ventilation openings and visible exterior parts. Even an outdoor sauna that is temporarily unheated should be inspected and ventilated regularly.

If changing guests use the sauna, operation of the installed wood-fired stove should be explained clearly. This includes suitable fuels, what to do if smoke develops, handling hot surfaces, ventilation and final closing checks. Clarify cleaning, maintenance, insurance and suitability for the intended use as well. Inexperienced people should not operate the stove without instruction.

A documented check routine between occupancies makes supervision easier. Check that the interior is clean and dry, the door works, access routes are clear, and the stove surroundings and chimney are visibly sound. Keep firewood and accessories organised without using the sauna cabin or safety areas as storage. Do not use the sauna again after defects are found until their cause has been professionally resolved.
