Thermowood Barrel Sauna

HC150 barrel sauna – compact thermowood garden sauna for two

The Bloomcabin HC150 measures approximately 153 cm long, 194 cm wide and 204 cm high. With a footprint of around 2.97 m², it is among the most compact barrel saunas. It suits gardens, suitable terraces, courtyards or holiday homes where space is limited. The interior provides a comfortable seated sauna for two people. With an internal height of approximately 175 cm, it is designed for use while seated. If you do not need a reclining area or separate changing room, this space-saving cabin uses its entire interior as a sauna room.

This page explains the space and technical requirements for the model, how the short barrel shape works in everyday use, and what to clarify before ordering and installation. Explore other sizes and designs in the Bloomcabin sauna range.

What makes this model special

Your choice should consider the dimensions, internal height, seated use and electric heating together. It is equally important that the site provides enough room for assembly, access and future inspections.

Thermowood: the defining material of the HC150

The HC150 is made from FSC®-certified thermowood. Thermal treatment means the wood absorbs less moisture and moves less in changing conditions than untreated timber. These qualities are especially relevant for a barrel sauna that stays outdoors year-round. They do not replace correct installation or regular checks. Wood remains a natural material whose appearance changes over time through sunlight, rain and use.

The visible grain and warm timber character shape the sauna’s appearance. The HC150 combines well with timber decking, natural stone, gravel and planted garden areas. However, it should not be enclosed directly by dense vegetation. Falling leaves, permanent shade and areas that dry poorly increase cleaning needs. An accessible location makes it easier to inspect exterior surfaces and remove organic deposits promptly.

UV light and weather can alter the colour of exterior timber over time. This is normal for outdoor wood and does not automatically indicate dirt. Follow the supplied manufacturer care instructions and use suitable products only. Check the barrel bands, visible fixings, door and seals regularly. Have any issues addressed early so moisture cannot enter and operation is not affected. Aggressive cleaners and hard brushes can damage the surface. Avoid covers that remain wet for long periods, as the wood beneath them will dry less effectively.

Clarify the base and electrical connection before assembly

The HC150 is designed to operate with an electric sauna heater. The heater, controls, sauna stones and accessories included with your order depend on the selected configuration. Do not rely on images alone; read the specific product description and delivery information fully before purchase. This shows which components are included and what accessories or services must be arranged separately.

Electrical planning should be completed before the sauna is assembled. A REWS-authorised professional with the appropriate scope should assess the required supply cable, protection and connection method using the manufacturer’s information and local conditions. Do not create a temporary connection using unsuitable cables or plugs. Agree the supply-cable position with the installation site early. Retrofitted cable routes can unnecessarily disrupt the garden or require finished surfaces to be opened again. After commissioning, keep documentation for the heater, controls and electrical connection together in a dry, easy-to-find place. During a later inspection, the professional can then identify installed components and how the system is isolated from the mains. Clearly label the relevant circuit breaker where appropriate. Ensure every user understands the basic operating and shut-down steps. Unauthorised changes to the supply, controls or heater are not routine maintenance and should only be made after professional assessment.

The barrel sauna requires a level, load-bearing and permanently stable base. Local settlement or differences in level can place stress on the structure and affect door operation. Rainwater must not collect beneath the sauna. Plan controlled drainage and keep drainage routes clear. If the HC150 is placed on an existing terrace, its load capacity must suit the complete structure, equipment and use. Do not judge this from the visible finish alone; the supporting construction beneath it is equally important.

Planning treatment, clearances and any construction, electrical or fire-safety requirements depend on the proposal and site. Before ordering, ask a perit to confirm the Planning Authority classification and consult appropriately qualified professionals. You can also find general guidance under outdoor sauna planning advice.

Which locations and users suit the HC150?

Whether the HC150 is right for you depends mainly on who will use it regularly, how much space is permanently available, and whether a compact seated cabin meets your expectations.

HC150 or HC 180 – which barrel length fits better?

The HC150 is designed for the smallest possible footprint and seated use. It is particularly appealing where every additional centimetre in the garden or on a suitable terrace matters. Space saving should not decide the choice automatically. Consider how often two people will sauna together, how much freedom of movement you expect, and what seating distance feels comfortable. A careful comparison prevents you choosing the shortest option when more space is available and a longer cabin would suit you better.

The HC 180 is approximately 34 cm longer, giving more room to move and stretch your legs. It is also designed for two people and has an internal height of 175 cm. The extra length primarily improves the feeling of space; the HC 180 is not designed as either a standing or reclining sauna. Mark out the external outlines of both versions at the planned site. This lets you see how the additional length affects paths and usable garden space, and whether the extra interior justifies the larger footprint for you.

If you need a protected area for changing or storing belongings, neither the HC150 nor a longer sauna cabin alone will be enough. Consider a model with a changing room instead, such as the N 210 . A changing room provides a protected place for storage and changing, but requires additional space. Decide whether the HC150’s especially compact construction or a separate area matters more to you.

Plan access, cooling-off space and care sensibly

Plan the route between the house and sauna so that it remains safe to walk in darkness and wet weather. A firm slip-resistant surface and well-positioned lighting matter more than purely decorative garden features. Keep loose cables, garden tools and uneven stepping stones out of the way. Leave enough space in front of the door to open it, enter and exit. A practical routine also includes somewhere to cool down calmly. Depending on your property and habits, this might be an outdoor shower, cold-water plunge or resting place. Keep water areas and electrical equipment clearly separate, and have the detailed layout professionally checked.

After every sauna session, moisture created inside must be able to escape. Follow the ventilation and operating instructions for your chosen equipment. Remove damp towels and other loose items, gently wipe away visible moisture and check that air inlets and outlets remain clear. Close the cabin fully only once the specified ventilation process is complete. Let the heater and interior cool sufficiently before cleaning. Use suitable mild cleaners sparingly on seats, floor and other wooden parts, and avoid heavily soaking surfaces or leaving standing water. Include the door, fittings, seals and ventilation openings in regular visual checks. This helps you identify stiff-moving parts, deposits or changes to the timber early. In a holiday home with changing users, assign clear responsibility for ventilation, cleaning and final checks. Brief care after each use is easier to manage than infrequent, demanding cleaning sessions.

Prepare the delivery route, working area and assembly sequence

Check the entire transport route from the unloading point to the installation site. Alongside gate widths, consider steps, low passages, tight turns, slopes and delicate surfaces. Prefabricated components need enough space to be carried and turned safely. Remove movable obstacles before delivery or assembly and protect sensitive surfaces. If the garden is accessible only through the house, a narrow passage or neighbouring land, arrange access in good time. Also prepare for first use: remove packaging and tools, keep the route to the sauna clear and visible after dark, and have the electrical connection professionally completed. Plan a dry place outside the cabin for towels, robes and personal belongings, as the HC150 has no changing room. This keeps the small interior clear and routes between the house, cooling area and sauna organised. Before the appointment, also confirm who will receive the delivery and whether the unloading point and route are accessible at the agreed time.

The site itself needs more clear working space than the sauna’s eventual footprint. Components must be set down, sorted and assembled safely. Keep the area free of garden furniture, planters and stored materials. Once assembled, the door should open without obstruction. Leave exterior surfaces, barrel bands and connection points accessible for later visual checks. A sauna positioned too close to walls, railings or hedges makes maintenance harder and can prevent neighbouring areas from drying properly.

Coordinate the sequence of base preparation, assembly and electrical connection. The supply cable must be available at the planned point without obstructing assembly work. Provide a clean, level assembly area that is readily accessible to everyone involved. Check delivered components and the ordered configuration against the documentation before assembly begins. Keep assembly, operating and care instructions dry and easy to locate afterwards, so they are available during commissioning, maintenance or later inspections.
