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 one of the most compact barrel saunas. It suits gardens, suitable patios, 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 sitting. If you do not need a reclining area or separate changing room, this space-saving cabin uses its entire interior as the sauna room.

This page explains the space and technical requirements for the model, how its short barrel form 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 decision should consider the dimensions, internal height, seated-sauna use and electric heating together. It is equally important to have enough room at the site for installation, access and future checks.

Thermowood: the defining material of the HC150

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

Visible grain and the warm character of wood define the sauna’s look. The HC150 works well beside timber decks, natural stone, gravel areas and planted garden spaces. Even so, avoid enclosing the sauna directly with dense planting. Fallen leaves, permanent shade and areas that dry poorly increase cleaning work. An accessible position makes it easier to inspect exterior surfaces and remove organic deposits promptly.

UV light and weather can gradually change the colour of exterior surfaces. This is normal for outdoor timber and is not automatically a sign of dirt. Follow the supplied manufacturer care instructions and use only suitable products. Regularly inspect barrel bands, visible fixings, the door and seals. Have any issues addressed early so moisture cannot enter and operation is not affected. Harsh cleaners and stiff brushes can damage the surface. Avoid permanently wet covers too, as the wood beneath them dries less effectively.

Clarify the base and electrical connection before installation

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 chosen configuration. Do not rely on images alone: read the specific product description and delivery details fully before purchasing. This shows which components are included and which accessories or services you may need to arrange separately.

Complete the electrical planning before the sauna is assembled. Have a competent, legally registered local electrical contractor use the manufacturer’s instructions and site conditions to determine the required supply, protection and connection arrangement. The contractor should complete the necessary inspection and testing and provide any applicable Certificate of Compliance documentation. Never improvise the connection with unsuitable cables or plugs. Agree the supply position early; retrofitted routes may disrupt the garden or require finished surfaces to be reopened. After commissioning, keep the heater, control and electrical-installation documents together in a dry, accessible place. This allows a contractor at a later inspection to identify the installed components and how to isolate the system from the electricity supply. Label the relevant circuit breaker clearly where necessary, and ensure every user understands basic operating and shut-down steps. Unauthorised changes to the supply, controls or heater are not routine maintenance and should be made only after professional assessment.

The barrel sauna needs a level, load-bearing and permanently stable base. Local settlement or changes in level can stress the structure and affect door operation. Rainwater must not collect beneath the sauna. Plan controlled drainage and keep drainage routes clear. If the HC150 will stand on an existing patio, its load-bearing capacity must suit the complete structure, equipment and use. Do not judge this from the visible surface alone; the construction beneath it also matters.

Whether permissions, setbacks or further building, electrical and fire-safety requirements apply depends on local circumstances. Before ordering or installation, clarify this with the relevant municipality and qualified professionals. You can also find general guidance under outdoor sauna planning guidance.

Which sites and users suit the HC150?

Whether the HC150 is right for you depends primarily 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 suits you?

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

The HC 180 is approximately 34 cm longer, providing more room to move and more legroom. It is also designed for two people and has an internal height of 175 cm. The extra length therefore primarily improves the sense of space; the HC 180 is not designed as either a standing or reclining sauna. Mark out the external outline of both versions at the intended site. This shows how the added length affects paths and usable garden space, and whether the larger interior justifies the additional footprint for you.

If you need a sheltered area for changing or storing belongings, neither the HC150 nor a longer sauna cabin on its own will be enough. Consider a model with a changing room, such as the N 210 . A changing room offers protected storage and changing space, but needs additional room. Decide whether the HC150’s especially compact design or a separate area matters more to you.

Plan access, a cool-down area and care sensibly

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

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 loose items, gently remove visible moisture, and check that intake and exhaust vents remain clear. Close the cabin fully only when the specified ventilation process is complete. Let the heater and interior cool sufficiently before cleaning. Use suitable mild cleaners sparingly on seats, the floor and other timber parts, and avoid heavily soaking surfaces or leaving standing water. Include the door, fittings, seals and ventilation openings in routine visual checks. This helps you notice stiff-moving parts, deposits or changes in the timber early. At a holiday home with changing users, assign clear responsibility for ventilation, cleaning and final inspection. Brief care after each use is easier to manage than infrequent, intensive cleaning.

Prepare the delivery route, work area and installation sequence

Check the complete transport route from the unloading point to the installation site. In addition to gate widths, consider stairs, low openings, tight turns, slopes and sensitive floor finishes. Prefabricated components need enough room to be carried and turned safely. Remove movable obstacles before delivery or installation and protect vulnerable surfaces. If the garden can be reached only through the house, along a narrow passage or over neighbouring property, arrange access well in advance. Also prepare for first use: packaging and tools must be removed, the route to the sauna should be clear and visible after dark, and the electrical connection must be 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 orderly. Before the appointment, also confirm who will receive the delivery and whether the unloading point and transport route will be accessible at the agreed time.

At the site itself, you need more clear working area than the sauna’s final footprint. Components must be laid down, sorted and assembled safely. Keep the area free of garden furniture, planters and stored materials. Once assembled, 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 care difficult and can prevent adjacent areas from drying properly.

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