Thermowood Barrel Sauna

HC 225: Thermowood barrel sauna for two to three people, suitable for use with a wood-burning heater

The Bloomcabin HC 225 is designed for couples, small families and friends who want more room than a mini barrel sauna while choosing not to have a separate changing area. At approximately 229 cm long, 194 cm wide and 204 cm high, it remains compact. Interior height is approximately 175 cm. With the full exterior length devoted to the sauna room, it provides longer benches and more legroom.

Capacity, dimensions and heating at a glance

Consider these features together: capacity, interior height and heating choice shape daily use just as much as the exterior dimensions.

FSC®-certified Thermowood with a classic barrel-sauna look

The HC 225 is made from heat-treated wood. Thermal treatment reduces moisture uptake and helps the timber remain more dimensionally stable than untreated wood.

Its visible grain and warm timber tone suit natural settings, cottages and wood decks particularly well. Beside a contemporary home, the rounded form can also make a deliberate contrast.

Even thermally treated wood responds to moisture and temperature. Inspect the barrel bands, fixings, door and seals regularly.

Traditional sauna bathing with a wood-burning heater

The HC 225 is suitable for a wood-fired sauna heater. Building the fire, hearing the wood crackle and adjusting heat through fuel and airflow make the warm-up part of the sauna evening.

A wood-burning heater takes more advance planning than an electric unit. Before installation, confirm the chimney route, heat shielding and the component manufacturer’s required clearances. Ask the municipality and local fire authority which permits, inspections or current fire restrictions apply to the site.

Choose the heater only after matching it to the exact HC 225 configuration and site. Rely on the inclusions listed in the specific quote and on the installation and safety instructions supplied for each selected component.

Plan the outdoor area around the lack of a changing room

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

The base must be level, capable of carrying the sauna and shaped so rain and meltwater drain away. No support point should settle or distort the barrel structure. Check the layers below the finished surface, not just what is visible. For an existing deck, assess its condition, capacity and drainage; for a new pad, match the sub-base to both the sauna and the site. Because soil and frost conditions vary across Canada, have the foundation approach checked locally rather than assuming one detail suits every region. Water must not pool under the timber or around the entrance.

Plan the sauna, heater and flue together when choosing the site. Chimney position affects required clearances from building elements, plants and other garden features. Access for inspection and cleaning must remain clear. Discuss the plan with the appropriate local professionals and authorities before assembly. Changes later can be difficult if branches, eaves or other conditions obstruct the intended chimney route.

Who may enjoy the HC 225 most

This model is especially well suited to households where two people usually use the sauna, a third joins from time to time and tending a wood fire 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 interior height, it offers notably more vertical space and is designed for up to four people.

Choose the HC 225 if compact exterior dimensions are the priority. If headroom, longer benches and a more open feel matter more, put the HCF 225 on your shortlist.

Mark out the footprint in your garden before buying

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

Use the documents for the exact version to review the bench layout. Decide which places will be used most often and whether the available bench length suits your height and preferred posture. Exterior dimensions alone cannot answer this comfort question.

Also plan the route between the house, storage area and sauna. Wet shoes, clothing and personal items do not belong on sauna benches. A dry storage spot and clear access let the interior remain dedicated to sauna use.

Plan location, access and cooling down together

A well-chosen location shortens the walk from the house and makes the sauna routine easier. The route should remain visible after dark, safe underfoot and free of tripping hazards. Check that doors and gates provide comfortable access and that the path remains usable in rain, snow, ice and cold weather. Lighting should cover the entrance and walkway without shining unnecessarily into the rest area. Have exterior circuits and lighting handled by a qualified local electrical contractor, with destination approvals confirmed before the work begins.

An accessible outdoor area is enough for cooling down. Plan a shower, plunge pool or swimming pool only where the space and intended use support it. Consider water supply, drainage, cleaning and winter shut-down. Runoff must not remain at the sauna base or make the path slippery. You can also allow room now for a later addition.

As rest periods take place outside the HC 225 cabin, sheltered nearby seating is practical. Position furniture, privacy screening and plants so access, heater maintenance and designated safety areas remain unobstructed. Maintain the required distances from hot equipment and the flue.

Inspect Thermowood regularly and clean it gently

UV light, rain and changing temperatures can alter the colour and surface of Thermowood over time; this is not automatically damage. What matters is preventing water from standing in one place and keeping dirt from blocking drainage. Keep the area around the barrel sauna clear so air can circulate and the wood can dry after rain.

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

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

Confirm contents, delivery route and local requirements early

Review the selected configuration carefully before ordering. Suitability for a wood-burning heater does not automatically mean that the heater, sauna stones, chimney parts, heat shields and all assembly accessories are included. The stated contents of the specific offer are decisive. Also clarify which services are planned for assembly, heater installation and flue work, and which tasks must be completed separately by suitable professionals.

Assess the complete delivery route from the planned unloading point to the prepared site. Narrow gates, wall projections, stairs, steep slopes, soft ground, low branches and tight turns can complicate moving large components. Check height restrictions and turning space as well as available width. Keep access clear on delivery day and confirm in advance which lifting or moving equipment is needed for the chosen delivery method.

Start with the exact site: identify the province or territory and municipality, then ask the relevant authorities about zoning, setbacks, the sauna structure, the wood-burning appliance and flue, and any electrical work. Canada’s National Model Codes do not by themselves determine which rules apply at that location. Required drawings, permissions and inspections depend on the property, selected configuration and local framework. Obtain project-specific guidance before fixing the base or chimney position. Further information is available under Useful information.

Assess sitting comfort in the exact configuration

With an interior height of approximately 175 cm, personal comfort depends not only on height but also on how you move inside. Check whether regular users can enter, sit down and stand up comfortably. Someone who wants to change inside or move upright frequently has different needs from someone who mainly sits.

Include the exact bench arrangement in your assessment. Where possible, compare the stated dimensions with a familiar bench and consider the space your knees and legs need in your preferred position. This gives a more realistic indication of whether the selected version suits your use.

If upright movement is more important, compare the HCF 225, which has an interior height of around 210 cm.

Does a wood-burning heater suit your routine?

Before every sauna evening, firewood, fire starters and necessary accessories need to be ready. Heating requires active attention, while residual heat and ash need proper handling afterwards. Consider whether this recurring routine fits your day-to-day life rather than choosing solely by preferred heat source.

Operation also involves tasks beyond the sauna session: storing firewood dry, keeping the heater area clean, maintaining access to the chimney and replenishing supplies in good time. Storage must be outside the hot cabin and must not narrow safety, access or working areas. Allowing for this in your garden plan avoids improvised solutions later.

Where several people use the sauna, make clear who operates the heater and who ventilates, cleans and locks up afterwards. Children and inexperienced guests need appropriate supervision and clear guidance around hot surfaces. The operating manual and requirements for installed components remain authoritative for use and safety.

Careful preparation protects components and supports final checks

Before assembly begins, the base, access route and storage area should be fully prepared. Delivered timber parts need a clean, dry, protected place until installation. Check delivery against the relevant documentation and report visible discrepancies before fitting components. Open packaging without using unsuitable tools that could damage timber surfaces.

Follow the model-specific assembly instructions and do not alter load-bearing or heat-protection components yourself. The round barrel construction must be levelled evenly; an unsuitable base cannot be corrected by tightening afterwards. Doors and fittings can only be assessed reliably once the sauna is correctly positioned. Heater, chimney and any electrical connections are subject to their respective specialist requirements. Carry out visual and functional checks before the first heating.

Keep assembly, operating and care documents with the information for the installed heater and chimney. This helps with later cleaning, spare-parts enquiries and discussions with tradespeople. Photos of concealed cable routes or connection details may also be useful. A documented handover is particularly helpful when assembly and technical installation are completed by different contractors.

Ventilate fully and allow to dry after every sauna session

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

Before a longer break in use, the interior should be clean and dry. Check that vents are unobstructed and no textiles or organic residue remain. Do not cover the wooden sauna airtight, as trapped moisture escapes less easily. Any additional weather cover 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 for rain ingress, spilled water during sauna use or restricted air movement. Seek professional advice if the cause cannot be identified clearly.

Rainwater must be able to run off freely

The rounded barrel form defines the appearance of the HC 225. Keep the immediate perimeter free of soil, leaves and objects that hold moisture against the wood or make inspection difficult. After heavy rain, check that the prepared drainage still works. Beds, edging or paving added later must not alter the water route.

Overhanging branches, constantly spraying irrigation and dense vegetation can slow drying and hinder access for maintenance. Adequate space around the sauna makes it easier to inspect exterior wood, barrel bands and connections. Plants must not reach hot components or the flue. Before adding a roof or cladding, establish whether it is technically permitted and compatible with the intended construction.

Keep the entrance and walking route clear and safe so the door can operate freely. Do not use tools or products for cleaning and care that could damage the wood, 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 objects from required safety areas. This visual check does not replace regular professional maintenance.

Clear responsibilities matter especially at a cottage

At a privately used cottage, the HC 225 is particularly practical if there is already room indoors for changing and dry towels. For longer absences, decide who will inspect the interior, door, vents and visible exterior components. Even an outdoor sauna that is temporarily unheated should be checked and ventilated regularly.

If different guests use the sauna, provide clear instructions for the installed wood-burning heater. Cover suitable fuels, what to do if smoke develops, safe conduct around hot surfaces, ventilation and the final check after use. Cleaning, maintenance, insurance and suitability for the intended use also need to be addressed. Anyone unfamiliar with the heater should receive instruction before operating it.

A documented inspection routine between stays makes care easier. Check for a clean, dry interior, proper door operation, clear access routes, and the visible heater area and chimney. Firewood and accessories must be kept orderly without using the sauna room or safety areas for storage. If faults are found, do not use the sauna again until their cause has been professionally clarified.
