Thermowood Barrel Sauna

HC 180 – compact barrel sauna for two people

The Bloomcabin HC 180 is a compact seated sauna that offers extra length compared with the HC150 without reaching the dimensions of a substantially larger model class. Its interior is designed for two people to enjoy sauna sessions together. Before deciding, consider whether this seating-focused layout meets your expectations. Leave enough space around the sauna body for the open door, access, cleaning and care. Also establish early whether all components can be transported to the installation site and whether a clear, accessible work area is available for assembly.

Here you can learn how dimensions, barrel shape, thermowood and technical requirements affect everyday use. Find an overview of other designs in the Bloomcabin sauna range.

Dimensions and equipment of the HC 180

Capacity, external dimensions, internal height and heating type should be considered together. The dimensions determine whether the sauna fits the intended site and allows the desired seating position. With electric heating, the heater, controls, accessories, power supply and cable route must be coordinated in advance. Consider both professional installation and subsequent operation in accordance with the relevant appliance instructions. The HC 180 is suitable when its compact seating concept matches the available garden space and technical conditions on site.

Thermowood and barrel construction in daily use

The HC 180 is made from FSC®-certified thermally treated wood. Heat treatment reduces moisture absorption and improves dimensional stability. These properties benefit a sauna permanently installed outdoors, but they do not replace regular care. Wood remains a natural material that responds to sun, rainfall, temperature changes and moisture created during use. Differences in colour and grain, along with gradual colour change, are part of its natural appearance. To maintain an even look where possible, use only care products explicitly suitable for thermally treated wood and for the relevant indoor or outdoor area.

The barrel shape determines both appearance and the feel of the interior. Its curve avoids tall, unused corners, keeping the interior focused on seating and sauna bathing. The curved outer surface should nevertheless remain easy to reach at the installation site. Do not position the barrel so close to walls, fences or dense planting that cleaning and visual inspections become difficult. Adequate clearance makes it easier to remove leaves and dirt, inspect the barrel bands and spot changes in the wood early.

Clean exterior surfaces gently and avoid methods that roughen the wood or force high-pressure water into joints. Check barrel bands, fixings and sealing areas for loose connections, unusual gaps or persistent moisture. Remove organic deposits before they become established. Assess more exposed and sheltered areas separately, as colour and surface condition can develop differently. Do not use aggressive household cleaners or unsuitable coatings; use only products intended for the relevant timber surface.

Clarify the site, electrical connection and transport route early

The HC 180 is intended for an electric sauna heater. Supplied components depend on the selected product configuration. Before ordering, check whether the heater, controls, sauna stones and desired accessories are included or need to be ordered separately. Also ensure that every selected component is intended for this sauna model. Product images may show equipment examples and do not replace details of the specific configuration. The product description and the related assembly and operating instructions are authoritative.

Have the electric sauna heater connected by a competent, legally registered local electrical contractor, preferably before the foundation and cable route are finalised. The available power supply, required cables, their route to the sauna and the heater and control requirements all need checking. Early coordination avoids reopening completed garden areas or running temporary cables across walkways. Commission the system only once installation and connection have been completed in line with the technical documentation and properly inspected and tested.

The kit construction with prefabricated elements can make transport along garden paths easier, but it does not replace careful assessment of the route. Measure gate widths, passages and narrow points; also consider steps, slopes, tight turns and delicate surfaces. Every component must be movable safely from the unloading point to the installation site. Assembly requires a clear work area, suitable tools and enough time for careful alignment. A second person is particularly helpful with larger elements. Keep components dry and protected until assembly, sort the fixings clearly, and follow the specified sequence, since early inaccuracies in a barrel construction can continue through the whole build.

Before ordering and assembly, clarify the building-control, boundary, electrical and fire-safety requirements for your specific site. Requirements can depend on the property, location and chosen design. In Cape Town, minor-work classification does not itself determine whether approval is needed; elsewhere, check with the relevant municipality. On rented or shared land, ownership arrangements and existing building restrictions may also matter. General guidance cannot replace assessment of the individual project.

Who the HC 180 suits especially well

Whether the HC 180 is right depends less on the building type than on the intended routine. The heated seating room is the focus; changing, storage and cooling down must be organised outside. Decide too who will operate the heater and controls, and who will ventilate, clean and report visible changes after a sauna session. Clear responsibilities matter especially where the sauna is used by different people. This helps establish in advance whether the compact layout will work in everyday life.

HC 180 compared with HC150, HC225 and N 210

The HC150 requires even less external length. It is therefore the natural alternative where every centimetre at the installation site matters and the smallest possible version takes priority over additional room to move. Do not base the decision between the two models on a product image alone. Compare the complete external dimensions, mark out both options at the intended site and assess how much space remains for access and care after installation.

The larger HC225 is worth considering when additional interior room matters more than especially compact external dimensions. Whether the larger version is worthwhile depends on intended use and available garden space. In addition to the sauna body, the foundation, delivery and integration into the outdoor area all require more room. Within this comparison, the HC 180 remains the compact two-person solution between the shorter HC model and the larger version.

The N 210 follows a different spatial concept: it incorporates an anteroom and offers approximately 195 cm of internal height. This matters if you want a transition area between the garden and hot sauna room, or more height. The HC 180 has no such additional area and concentrates its dimensions on the actual seated sauna. An anteroom is not automatically better, but it changes the routine: without one, you need a suitable dry place outside the HC 180 for robes, towels and shoes. This comparison helps you choose a model according to intended use rather than exterior appearance alone.

Plan access, a cooling-down area and privacy around the sauna

Start planning with the route between the house and sauna. It should remain safe to use in darkness, wet weather and cooler conditions. A slip-resistant surface, unobstructed walkway and suitable lighting make use more pleasant. Leave enough space in front of the door to enter and exit freely. Also decide where you want to cool down and rest after sauna bathing, and how much privacy you want there. An outdoor shower or cold-water plunge can complement the area but is not required to use the HC 180.

The base must be stable, level and suitable for the construction. Reliable drainage is equally important so rainwater does not remain beneath the sauna. Check where water from the roof area, adjoining surfaces and, where applicable, the cooling-down area will drain. A persistently damp environment places strain on wood and makes care harder. The underside should remain ventilated and accessible for inspection as far as the assembly requirements permit. Do not plant so close to the barrel that branches, leaves or growth continually touch the surface. A clean perimeter makes visual inspections easier and prevents vegetation from concealing early changes.

Practical routines for use and care

Before heating, check that the interior is tidy, ventilation areas are clear and no textiles or other items are lying on the heater. Operate the heater and controls only in accordance with their instructions. Do not cover the heater. If unusual smells, visible damage or technical irregularities occur, keep the sauna switched off until the cause has been professionally checked. A brief check before every use is especially sensible when several people or changing guests use the sauna.

After use, the cabin must be able to release moisture. Remove wet textiles, dry heavily used surfaces where needed and ventilate according to the sauna and heater instructions. Robes and towels should not remain permanently in the warm interior. A clean sauna towel protects the seating surface from direct soiling and must dry completely afterwards. Use only a small amount of water and a product suitable for the relevant surface, so the interior does not become unnecessarily wet. Regular ventilation, drying and light cleaning are more effective than rare, intensive cleaning.

At the beginning and end of longer periods of use, a more thorough visual inspection is advisable. Check exterior timber, interior surfaces, door operation, sealing areas, barrel bands, fixings and the condition of the base. Remove leaves and other deposits, and keep intended drainage routes clear. Technical components should be checked in line with their documentation; electrical irregularities require a competent, legally registered local electrical contractor. Recording or photographing visible changes can help you track their development. This makes it easier to distinguish normal timber colour changes from issues that should be checked promptly.

Before a longer break in use, the interior should be clean, dry and free of textiles. Keep operating instructions, details of the selected configuration and electrical-installation documents together in an accessible place. Before recommissioning, check that the door and access are fully usable and that no visible impairment affects technical components; a competent, legally registered local electrical contractor must assess electrical irregularities. Well-organised documentation simplifies later maintenance and is particularly useful in holiday homes or after a change of owner, helping pass on reliable information about the installed version.
