Thermowood Barrel Sauna

HC150 barrel sauna – compact thermowood garden sauna for 2

The Bloomcabin HC150 measures approximately 153 cm long, 194 cm wide and 204 cm high. With a footprint of about 2.97 m², it is among the most compact barrel saunas. It suits gardens, suitable patios, courtyards or cottages where space is limited. Inside, 2 people can enjoy a comfortable seated sauna. The interior height of approximately 175 cm is intended for sitting. If you do not need a reclining bench or separate changing area, this space-saving cabin dedicates its full interior to sauna use.

This page covers the space and technical requirements for the model, what the short barrel format is like in everyday use, and what to confirm before ordering and installation. Explore other sizes and designs in the Bloomcabin sauna range.

What sets this model apart

The decision comes down to the dimensions, interior height, seated-sauna layout and electric heating. It is equally important to have enough room at the site for assembly, access and future checks.

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 through changing conditions than untreated timber. That is particularly useful for a barrel sauna kept outdoors, but it does not replace correct installation or regular inspection. Wood remains a natural material whose appearance changes over time through sunlight, precipitation and use.

The visible grain and warm character of the timber shape the sauna’s look. The HC150 can complement timber decks, natural stone, gravel and planted garden areas. Avoid enclosing the sauna tightly with dense vegetation. Fallen leaves, constant shade and areas that dry slowly increase cleaning requirements. An accessible location makes it easier to inspect exterior surfaces and remove organic debris promptly.

UV light and weather can gradually alter the colour of exterior timber. This is normal for outdoor wood and does not automatically mean it is dirty. Follow the supplied manufacturer care instructions and use suitable products only. Check the barrel bands, visible fixings, door and seals regularly. Address anything unusual early to prevent moisture ingress or impaired operation. Harsh cleaners and stiff brushes can damage the surface. Avoid covers that stay wet for long periods, as the wood beneath them will dry more slowly.

Confirm the base and electrical connection before installation

The HC150 is intended for use with an electric sauna heater. The heater, controls, sauna stones and accessories supplied vary with the configuration you select. Check the exact product description and included-items list rather than relying on photos. You can then see what arrives with the sauna and what equipment or services must be arranged separately.

Settle the electrical plan before assembly. Have a qualified local electrical contractor use the manufacturer’s instructions and site conditions to determine the supply, circuit protection and connection method, and to confirm any product approval or inspection required at the destination. Do not improvise with unsuitable temporary cables or plug connections. Decide where the supply will enter before site work starts; adding a route later may disturb landscaping or mean reopening finished surfaces. After commissioning, keep the heater, controller and electrical records together in a dry, accessible place. They will help a professional identify the installed equipment and isolate it safely during future work. Label the applicable breaker if advised, and make sure users understand the normal controls and shut-off procedure. Alterations to the supply, controller or heater require professional review rather than routine owner maintenance.

The barrel sauna needs a level, load-bearing and permanently stable base. Local settlement or unevenness can stress the structure and affect door operation. Rainwater must not collect beneath the sauna, so plan controlled drainage and keep drainage routes clear. If placing the HC150 on an existing patio, its capacity must be suitable for the full structure, equipment and use. Do not judge this solely by the visible surface; the supporting construction underneath also matters.

Before ordering, identify the province or territory and municipality for the site, then ask the relevant authorities which permits, setbacks, electrical approvals and fire-safety rules apply to the project. Discuss the installation with appropriately qualified local professionals as well. More general preparation advice appears in outdoor sauna planning guidance.

Which locations and users suit the HC150?

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

HC150 or HC 180 – which barrel length is the better fit?

The HC150 prioritizes a very small footprint and seated use. It is worth considering when each additional centimetre in a garden or on a suitable patio matters, but size alone should not decide the purchase. Think about how often 2 people will use the sauna together, the movement space you expect and the seating distance you find comfortable. Comparing the models can prevent you from choosing the shortest cabin when the site can accommodate a longer one that better suits your preferences.

The HC 180 is approximately 34 cm longer, providing additional movement and legroom. It is also designed for 2 people and has an interior height of 175 cm. The added length mainly improves the sense of space; the HC 180 is not a standing or reclining sauna either. Mark out both exterior outlines at your intended location. This reveals how the extra length affects paths and usable garden space, and whether the larger interior justifies the additional footprint for you.

If you need a sheltered place to change or set down belongings, neither the HC150 nor a longer sauna cabin alone will provide it. Consider a model with a changing room, such as the N 210 . A changing room gives you protected storage and changing space, but needs additional area. Decide whether the HC150’s very compact build 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 it remains safe to use 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 equipment and uneven stepping stones out of the way. Leave enough room at the door to open it, enter and exit. A comfortable sauna routine also needs somewhere to cool down calmly. Depending on the property and your habits, this could be an outdoor shower, cold-water tub or resting spot. Keep water areas clearly separate from electrical equipment and have the detailed plan checked professionally.

After every sauna session, moisture created inside needs to escape. Follow the ventilation and operating instructions for the equipment selected. Remove damp towels and loose items, gently wipe away visible moisture and check that supply and exhaust vents are clear. Close the cabin fully only after the specified ventilation cycle is complete. Let the heater and interior cool sufficiently before cleaning. Use suitable mild cleaners sparingly on benches, floor and other timber parts; avoid soaking surfaces or leaving standing water. Include the door, hardware, seals and vents in regular visual checks. This helps identify sticking parts, deposits or changes in the wood early. At a cottage with changing users, assign responsibility for ventilation, cleaning and the final check. Brief care after each use is easier to manage than infrequent, intensive cleaning.

Prepare the delivery route, work area and assembly sequence

Check the complete route from unloading point to installation site. Beyond gate widths, look at stairs, low openings, tight turns, slopes and delicate surfaces. Prefabricated components need enough room to be carried and turned safely. Remove movable obstacles before delivery or assembly and protect vulnerable surfaces. If the garden is accessible only through the house, along a narrow passage or across a neighbouring property, arrange access well in advance. Prepare for first use too: remove packaging and tools, keep the sauna path clear and visible after dark, and have the electrical connection professionally completed. Since the HC150 has no changing room, provide a dry spot outside the cabin for towels, robes and personal belongings. This keeps the small interior clear and the routes between house, cool-down area and sauna orderly. Also confirm who will receive the delivery and whether the unloading point and transport route will be accessible at the agreed time.

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

Coordinate base preparation, assembly and the electrical connection. The supply cable must be available at the planned point without obstructing construction. Provide a clean, level assembly area that all involved can access easily. Check the delivered components and ordered configuration against the documentation before assembly starts. Then store installation, operation and care instructions somewhere dry and easy to find for commissioning, maintenance and later inspections.
