Thermowood Barrel Sauna

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

The Bloomcabin N 210 offers a compact barrel sauna for anyone wanting an entrance area separate from the sauna room without installing an oversized garden sauna. Its rounded construction divides into a heated sauna room and an anteroom at the entrance. You therefore do not step straight in from the garden to the hot room and have a sheltered place to arrive before your sauna session. On limited garden space, 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 operation. Explore further designs and sizes in the Bloomcabin sauna range.

What the N 210 features mean 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 how you plan to use it.

FSC®-certified thermowood in a classic barrel construction

The N 210 is made from FSC®-certified, heat-treated timber. Heat treatment reduces moisture absorption and improves dimensional stability. This benefits a sauna that remains outdoors, where the construction is exposed to changing humidity and rain. Thermowood is not maintenance-free, however. Rainwater must be able to run away freely, and moisture must not collect around the lower timber sections. Air should also circulate below the construction so the wood can dry after wet weather.

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

As a natural material, timber can move with seasonal changes, alter in colour and develop visible signs of use. Check the barrel bands, fittings, door operation and accessible timber areas regularly. Any adjustment and care steps must follow the product and assembly instructions. Unsuitable film-forming treatments, or treating surfaces that become hot without expressly confirmed suitability, can affect surfaces and the sauna experience. Appropriate material care matters more than applying coatings as often as possible.

How to plan the heater, base, access and drainage

Depending on the available configuration, the N 210 can use electric or wood-fired heating. For an electric heater, a competent, legally registered local electrical contractor must confirm equipment compatibility, plan and install the appropriate supply, and complete applicable inspection, testing and Certificate of Compliance documentation. The technical data for the selected heater are decisive; an existing outdoor socket is not automatically sufficient. Clarify the cable route, required components and maintenance access early to avoid temporary exposed cables or reopening assembled parts later. A wood-fired heater needs different preparation. Ask the relevant municipal building-control and fire authorities about the appliance, flue, ventilation, heat protection, clearances, safe operation and local smoke restrictions. Its position relative to buildings, property boundaries, plants and combustible objects may affect the site choice. Store firewood safely and dry without obstructing escape or operating routes. Choose the heater not only for its atmosphere, but because its technical and practical requirements can be met reliably on your property. Before ordering, check exactly which heater, controller and accessories belong to the selected configuration. Product images may show features that are not automatically included with every version. Assembly and commissioning must follow the documents for the sauna, heater and selected additions. Do not alter safety clearances or structural components 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, point foundations or a structurally designed deck construction. The suitable solution depends on ground conditions, substructure and the intended bearing points. A lawn that merely appears level is not enough: settlement or ground movement can jam doors, strain components or direct water the wrong way. Check the bearing points and every requirement in the assembly instructions before construction begins.

Plan drainage and ground clearance when preparing the base. Rainwater must not gather beneath the sauna or directly around the 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 be directed onto the barrel structure. A ventilated underside helps it dry after rain. At the same time, the substructure must safely support all intended bearing areas and must not settle through loose or yielding materials.

Also plan the delivery and assembly route. Narrow gates, walls, hedges, stairs or low roof overhangs can complicate delivery and installation even when the finished sauna fits its intended space. Sufficient working room must also remain around the assembly site. Ask the relevant municipality which approval route, planning-scheme controls and building-line requirements apply, and coordinate any registered electrical contractor and fire-safety guidance needed for the project. 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 an anteroom, greater internal height and compact barrel shape. These qualities can be particularly useful in the following situations.

N 210 or a barrel sauna without an anteroom?

With the HC150 and HC180, the available length is devoted entirely to the sauna room. These models may be preferable when the footprint should stay as small as possible and you do not need a separate entrance area. External length is only a first guide. More important is how the interior is divided and whether there is already a sheltered place beside the sauna for changing or putting down textiles.

The N 210 deliberately uses part of its overall length for the anteroom. This is useful when textiles should not be kept in the hot area or the outer door should not lead directly into it. In return, that part of the footprint is not available as additional sitting or reclining space. Buyers should weigh whether spatial separation matters more than a sauna room extending along the full length. Reviewing the product drawing helps assess door positions, bench layout and circulation areas realistically.

If you would like an anteroom 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 must remain limited. Do not measure only the clear ground area. Include access, door swing areas, side working space and every area that will need maintenance later. Only this overall assessment shows which model truly fits the intended position.

Safe access, proper drying and gentle timber care

The route from the house to the sauna should be free of trip hazards, as slip-resistant as possible when wet and adequately lit. Lights must neither dazzle nor be installed where they affect hot or electrical components. An outdoor shower, cold-water plunge pool or sheltered seating area can be planned for cooling down. Arrange these areas so nobody has to walk with wet feet over loose stones, smooth surfaces or unlit steps. Water from the cooling area must also not run towards the foundation or beneath the sauna. After every sauna session, moisture must be able to escape. Ventilate and dry the interior in line with the use instructions before leaving the sauna closed for an extended period. Remove damp towels, bathrobes and infusion accessories from the sauna and anteroom. This helps prevent odours, persistently damp contact surfaces and unnecessary stress on the timber. Before longer breaks in use, an additional visual inspection is advisable so small issues are not first noticed at the next heating cycle.

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

Assess internal height and bench area before buying

For size comparison, the more compact HC150 and HC180 models offer approximately 175 cm of internal height. The greater height in the N 210 makes entering, standing and moving easier. Because a barrel sauna has a curved ceiling, however, maximum height is not available across its full width. Taller people should therefore also check the ceiling line 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 height, number of users and bench layout. Before ordering, decide whether you will mainly sit upright, recline occasionally or use the sauna with several people. Then compare these expectations with the product drawing and the genuinely usable areas. External dimensions alone cannot show how many people can occupy the sauna room at once according to your personal comfort expectations.

It is best to walk through future use in its actual order: from the garden into the anteroom, on to the sauna room and then back to the cooling area. Check where shoes and textiles will go, how the doors open and whether several people can pass one another comfortably. This shows early whether the N 210 layout suits your routine or whether a model with a differently arranged interior would be more suitable.

Check the circulation space around the heater, doors and benches against the selected configuration. Add accessories only so that prescribed clearances, required airflow and all routes remain unobstructed. Consider not only operation, but also access for cleaning, inspection and maintenance.
