Thermowood Barrel Sauna

Bloomcabin N 210: barrel sauna with changing room for electric or wood-fired heater

The Bloomcabin N 210 is a compact barrel sauna for anyone wanting an entrance area separate from the sauna room without installing a large garden sauna. Its round structure is divided into a heated sauna room and a front changing room. You therefore enter the hot space from a sheltered area rather than directly from the garden. On a limited garden site, this layout can be more practical than a longer, undivided interior. Whether it suits you depends on your routine and site conditions. Consider the internal layout, heater type, base and routes between the house, sauna and cooling area.

This guide explains what matters for the N 210's layout, material, location and use. Explore further designs and sizes in the Bloomcabin sauna range.

What the N 210 equipment means in everyday use

Do not compare individual dimensions alone. The combination of layout, internal height, material and technical preparation shows whether the N 210 suits your property and sauna routine.

FSC®-certified thermowood in a classic barrel design

The N 210 is made from FSC®-certified, thermally treated wood. Heat treatment reduces moisture absorption and improves dimensional stability. This benefits an outdoor sauna exposed to changing humidity and rainfall. Thermowood is not maintenance-free, however. Rainwater must be able to drain away freely, with no moisture collecting around lower timber sections. Air should also circulate beneath the structure so the wood can dry again after wet weather.

The rounded barrel shape does more than define the N 210's appearance. In the sauna room, the ceiling follows the curved section, avoiding high, unused corners. At the same time, there are fewer straight wall surfaces than in a rectangular structure. Assess the placement of doors, benches and circulation areas using the product drawing rather than external dimensions alone. Its distinctive timber form can complement traditional gardens, timber decks or holiday homes without requiring an exclusively rustic setting.

As a natural material, timber can move through seasonal changes, alter in colour and develop visible signs of use. Check the barrel bands, fittings, door operation and accessible timber areas regularly. Any adjustments and care must follow the product and assembly instructions. Unsuitable film-forming treatments, or treating heated internal surfaces without confirmed suitability, can affect finishes and the sauna experience. Appropriate material care matters more than frequent coating.

Plan heater type, base, access and drainage

Depending on the available configuration, the N 210 can use electric or wood-fired heating. For an electric heater, use a licensed electrical professional to assess, plan and install the power supply for the intended site. The selected heater’s technical requirements are decisive; an existing outdoor power point is not automatically sufficient. Confirm the cable route, required components, and inspection and maintenance access early, avoiding temporary exposed cables or reopening assembled parts. A wood-fired heater needs different preparation. Plan the flue, suitable heat protection, manufacturer-specified clearances and safe operation. Before ordering, ask the local council and regional council about building consent, resource consent, air-quality rules and any current fire restrictions for the specific site and heater. Distances from buildings, boundaries, planting and combustible materials can affect placement. Store firewood dry and securely without obstructing escape or operating routes. Choose a heater whose technical and practical requirements can be met reliably, rather than deciding on atmosphere alone. Check exactly which heater, controller and accessories come with the selected configuration. Product images may show features not automatically included with every variant. Assembly and commissioning must follow the documentation for the sauna, heater and selected additions. Do not alter protective clearances or structural parts for visual reasons.

The sauna needs a permanently level, load-bearing and professionally prepared base. Depending on the property, this may be a concrete slab, suitable paving, pad foundations or an engineered deck structure. The right solution depends on ground conditions, sub-base and intended support points. Lawn that merely appears level is not enough: settlement or frost movement can jam doors, strain components or direct water incorrectly. Before construction, check the support points and all assembly-manual requirements.

Plan drainage and ground clearance while creating the base. Rainwater must not collect beneath the sauna or directly against lower timber sections. The surrounding surface should drain water reliably while the sauna itself remains level. Roof or surface water from neighbouring buildings must not run onto the barrel structure. A ventilated underside supports drying after rain. At the same time, the substructure must safely carry every intended support area and must not sink through loose or yielding material.

Plan the delivery and assembly route too. Narrow gates, walls, hedges, stairs or low eaves can impede delivery and installation even if the completed sauna fits the site. Leave sufficient working room around the assembly area. Before work starts, ask the local council whether the proposed sauna, foundation and use need building consent or resource consent. Building Code duties and district-plan controls can still apply where building work is exempt. Coordinate required electrical work and, for a wood-fired option, confirm local fire and regional air-quality requirements. Further guidance is available under Useful information.

When the N 210 fits your garden and sauna routine

The N 210 is especially appealing for its combination of changing room, greater internal height and compact barrel form. These features can be particularly useful in the following situations.

N 210 or a barrel sauna without changing room?

With HC150 and HC180, the available length is entirely devoted to the sauna room. These models may be more suitable where the installation area must remain as small as possible and no separate entrance area is needed. External length is only an initial guide. More important is how the interior is divided and whether a sheltered place for changing or storing textiles already exists beside the sauna.

The N 210 deliberately uses part of its total length for the changing room. This is useful when textiles should not be kept in the hot area or when the outside door should not open directly into it. In return, that part of the footprint is unavailable as extra seating or reclining space. Buyers should therefore weigh whether spatial separation matters more than a sauna room extending through the full length. Reviewing the product drawing helps assess door positions, bench arrangement and circulation space realistically.

If you want a changing room and have more space at the site, the larger N 250 is a useful comparison model. The N 210 is the more compact option for properties where the installation area needs to remain limited. Do not measure only the clear floor area. Include access, door-swing areas, side working space and all locations requiring later maintenance. Only this overall assessment shows which model truly fits the intended position.

Safe access, effective drying and gentle timber care

The route from house to sauna should be free of trip hazards, as slip-resistant as possible when wet and adequately lit. Lights must not dazzle or be positioned where they affect hot or electrical components. An outdoor shower, cold-water plunge or sheltered sitting area can be planned for cooling down. Arrange these areas so nobody has to walk with wet feet over loose stones, slippery surfaces or unlit steps. Water from the cooling area must not run towards the foundation or beneath the sauna. After every sauna session, moisture must be able to escape. Ventilate and dry the interior according to the use instructions before leaving the sauna closed for an extended time. Remove damp towels, bathrobes and sauna accessories used for pouring water from the sauna and changing room. This helps prevent odours, permanently damp contact surfaces and unnecessary stress on the timber. Before longer breaks in use, a visual check is also advisable so minor issues are not first noticed at the next heat-up.

Clean seating and contact surfaces gently without soaking the timber with large amounts of water. Use only products and methods suitable for the particular sauna and timber surfaces. Aggressive household cleaners, pressure washing and permanently wet cloths can damage finishes. Outside, pay particular attention to lower timber areas, joints, barrel bands, fittings and drainage. Remove leaves, soil and organic debris so timber dries quickly after rainfall. Also check that doors close properly and whether visible structural changes have occurred. If anything is noticed, follow the assembly and care instructions; safety-related work on the heater, electrics or flue belongs with qualified professionals.

Assess internal height and bench area before purchase

For size comparison, the more compact HC150 and HC180 models offer approximately 175 cm of internal height. In the N 210, the greater height makes entering, standing and moving easier. As a barrel sauna ceiling is curved, however, maximum height is not available across the full width. Taller users should therefore also check the ceiling curve and bench positions in the product drawing.

The stated bench area of around 139 × 198 cm runs along the sauna room. Whether it suits your preferred sitting or reclining position depends on body size, number of users and bench layout. Before ordering, decide whether you mostly sit upright, occasionally lie down or sauna with several people. Then compare these expectations with the product drawing and genuinely usable surfaces. External dimensions alone do not show how many people can use the sauna room simultaneously according to your personal comfort expectations.

It is best to walk through future use in its actual sequence: from garden to changing room, then into the sauna room and back to the cooling area. Consider where shoes and textiles will sit, how doors open and whether several people can pass comfortably. This helps you identify early whether the N 210 layout matches your habits or whether a model with a differently arranged interior would be more suitable.

Check the circulation areas around the heater, doors and benches for the selected configuration. Add accessories only where required clearances, necessary air circulation and all walkways remain intact. Consider not only use, but also access for cleaning, checking and maintenance.
