Clean-lined design for contemporary outdoor spaces
Straight walls, vertical exterior cladding and dark aluminium frames give Sana its crisp, contemporary architecture.
The square footprint makes it easier to position beside a terrace, pool or pergola. Still, leave adequate room for assembly, cleaning and exterior maintenance. A very tight fit may look orderly, but makes later access to components more difficult.
View the planned location from several directions: from the house, seating area and garden path. The window side, entrance and roofline, not only the front, shape how the sauna looks on your property.
Black or natural: two distinct garden looks
In the natural finish, the wood feels warm and works particularly well with decking, natural stone and green planting.
The black version is more striking and suits dark window frames, aluminium pergolas and minimalist outdoor settings especially well.
Consider maintenance as well as appearance at the actual location. Depending on the surroundings, dust, splash water or plant debris may show differently on black and natural finishes.
Light thermo-aspen creates a calm, open interior
The interior is lined with thermally treated aspen. Its light colour and subtle grain suit the sauna’s clean-lined design. Sauna towels or suitable seat pads protect bench surfaces from sweat and dirt during regular use.
Thermo-aspen offers a warm contrast to the dark aluminium frames. Daylight enters through the glazing, so sun position and viewing direction influence the atmosphere more than in a largely enclosed wooden sauna.
Light wood, glass and indirect lighting make the compact cabin feel more spacious. Clear lines and restrained wood grain also create a calm, unified interior.
70 mm CLT panels form the load-bearing structure
The three-layer, 70 mm CLT panels form the walls and contribute to the clearly defined rectangular building shape.
Because of the large-format solid-wood elements, the base, unloading, transport to the site and assembly must be coordinated early.
The ground must be load-bearing, permanently level and suitable for the structure. Effective drainage is equally important: rainwater must not collect at the base, and adjoining surfaces should guide water away without making access to the door uneven.
Choose rear or side window to suit the view
Sana is available in two layout versions: the window can be positioned at the rear or on the side.
The rear window suits a preferred view opposite the entrance. A side window can work better when Sana stands parallel to a terrace, pool or house wall. Consider both the seated view and visibility from outside.
Before ordering, mark out the footprint, door side and window position at the intended location. This shows whether walls, plants or garden furniture restrict the view and whether the door can open without projecting into paths or seating areas.
Electric heating with HUUM CORE and UKU Glass
The HUUM CORE is operated with the UKU Glass control unit. Its simple glass surface complements the modern interior.
The sauna requires a three-phase 400 V, 50 Hz electrical supply. Agree cable routing, protection, controls and connection with a REWS-authorised electrical professional with the appropriate scope before installation. Planning the supply only after the base is complete can create awkward cable routes and difficult-to-reach connection points.
No firewood store or chimney is required. Instead, plan the electrical cable route so that connection and maintenance areas remain accessible later.
Indirect LED lighting for a restrained atmosphere
The LEDs are positioned beneath the benches, so the light source itself remains discreetly in the background.
When used in the evening, the lighting enhances the warm colour of the thermo-aspen without illuminating the sauna like an ordinary room.
The indirect lighting is designed for atmosphere. Additional lighting in the adjacent outdoor area can therefore be helpful for cleaning and visual checks.
Flexible space for families, guests and relaxing sauna sessions for two
At full occupancy, seating comfort depends on body size, preferred distance and personal space. If several people will use the sauna regularly, assess the available bench area rather than relying only on the stated capacity.
The larger cabin can also suit couples who want more freedom of movement and personal seating space.
If you mostly sauna alone, weigh the additional garden space against the desired interior comfort. Sana is especially strong when occupancy varies and sauna sessions are shared.
Plan a base for a total weight of around 1,800 kg
The total weight of Sana is approximately 1,800 kg. The intended base must support the sauna permanently and must not settle unevenly under the load.
A professionally constructed concrete slab or comparably load-bearing solution may be suitable. The right approach depends on the existing ground and planned build-up and should be assessed by a qualified professional.
For an existing terrace or timber structure, a visual impression of stability is not enough. The structure, supports and condition must suit the actual load. Also allow for temporary loads during unloading and assembly.
Integrate Sana into a modern sauna and relaxation area
Its rectangular form allows Sana to combine well with a pergola, pool or contemporary terrace. Keep the entrance clear, and ensure routes between sauna and resting area remain safe to walk on when wet. Furniture must not obstruct assembly or maintenance access.
A pergola beside the freestanding sauna can create a sheltered resting place. For an outdoor shower or cooling-off area, controlled drainage is important so that splash water neither reaches the timber façade continuously nor remains on walking routes.
Repeat colours and materials from the sauna, terrace and pergola deliberately, without placing the components too close together. Adequate spacing keeps exterior surfaces accessible and easy to clean.
Sana and Elma L: different concepts despite contemporary styling
The Elma L differs in the thickness of its CLT elements, its large glazed front and the design of its benches.
Sana, by contrast, has a compact square footprint, two selectable window positions and less glazing.
Alongside the contemporary appearance, compare glazing area, bench layout and the effect of the footprint at your intended location. The deciding factor is which model suits your garden, terrace and available access.
Care for glass, thermo-aspen and exterior cladding correctly
Clean the glass with a product suitable for the glass and adjoining materials. Apply cleaner to a soft cloth rather than spraying it directly onto seals, aluminium frames or wood, and remove all residue.
After every sauna session, the interior must be able to dry fully. Remove damp towels, pads and loose items, wipe up visible moisture with a clean cloth and keep the existing ventilation clear.
The care required for the exterior cladding depends on the chosen finish. Check the weather-facing side, low-level areas and junctions especially for dirt or visible changes. Use only care products suitable for the relevant surface to avoid staining and uneven results.
Who is the Bloomcabin Sana right for?
Sana is especially suited to contemporary detached homes, pool areas and terraces where a clean-lined sauna is wanted as a permanent part of the outdoor space.
The model suits families, couples and guests who appreciate a bright cabin and generous personal seating space.
A permanently suitable location and professionally completed 400 V connection are essential. If these conditions cannot be met, Sana is not the right choice.
Sana in an urban garden: plan space and integration carefully
The compact square footprint helps it fit into clearly structured gardens. However, the external dimensions alone do not show the true space requirement. You also need room for installation and care, a freely usable door area and a suitable cable route.
At an overall height of 253 cm, Sana remains clearly visible even on a small plot. Assess the location not only on a plan, but also from house windows and key seating areas. Before making the final choice, ask a perit to confirm the applicable Planning Authority classification and site requirements.
Planting and fixed garden elements must not obstruct air circulation, façade care or access. Plants should not remain in continuous contact with wood or glass; adequate clearance also makes leaves and dirt easier to remove.
Check configuration and location together before ordering
Before ordering, make a simple site plan showing external dimensions, door side, chosen window position, electrical cable route and adjacent surfaces. This helps identify early whether the foundation, access and configuration work together.
Do not make your selection from product images alone. Assess the view at normal seated height and compare black and natural finishes directly with the terrace, façade and garden elements at the intended location.
Then have the proposed 400 V connection assessed for professional installation at the intended site. Compare the final order with your site plan and explicitly check the window position, exterior finish and technical equipment in the order documents.
Plan daylight and privacy in balance
The toughened glazing and aluminium frames give Sana a light, modern appearance. Position the sauna so users can still feel undisturbed inside.
An illuminated interior is easier to see into in the evening than in daylight. Check sightlines from the house, terrace, garden path and neighbouring outdoor areas both by day and with the internal lighting switched on.
Place screening so it protects from the relevant viewing direction without crowding the window or door. This preserves the sauna view while keeping exterior surfaces accessible for care.
How to make Sana comfortable for everyday use
The HUUM CORE is operated using the UKU Glass control unit. Before first use, every user should become familiar with operation and the required clearances around the heater. The supplied operating and safety instructions are authoritative.
A well-prepared approach makes regular use more enjoyable. Position hooks, shelves and textiles so that the movement area in the cabin stays clear. Outside the sauna, a dry place for a bathrobe, towels and suitable footwear is practical.
Carry out a quick visual check before every use: bench surfaces and passageways must be clear, and no items may be left around the heater. After switching off, check whether textiles or accessories remain in the cabin.
Solid CLT construction or traditional barrel form?
In a barrel sauna, the rounded shape and curved wall surfaces define the interior and exterior appearance. Sana instead uses rectangular CLT panels and looks like a small, clean-lined garden building.
Straight walls allow a different arrangement of windows and benches than a round cabin. Integration beside a terrace, pool or house façade therefore follows a distinctly different design principle.
Those seeking a rustic barrel look and the ritual of a wood-fired stove should choose another product family. Sana is for buyers who prefer clean lines, light thermo-aspen and electric heating.
Prepare the delivery route and assembly area completely
Before ordering, check the entire route from the possible unloading point to the foundation. Gates, walls, roof overhangs, steps, tight turns and soft lawns can complicate delivery or assembly even where there is adequate space at the final position.
Lifting and assembly work require more than the footprint itself to be clear. Depending on the delivery and assembly method, working space may also be needed at the sides and above. Confirm the specific requirements in advance, remove obstacles in good time and protect sensitive paths or terrace finishes.
Also decide who will handle unloading, temporary storage and assembly. Store components protected until assembly and according to the supplied instructions. Clear responsibilities prevent heavy components from being moved unexpectedly or stored unsuitably.
Inspect weather-facing and low-level areas regularly
Regularly remove leaves, soil, splash marks and other deposits from exterior surfaces. Check areas near the ground and places where plants or garden furniture obstruct airflow particularly closely. Fresh dirt can usually be removed more gently than embedded residue.
Keep accessible roof areas and drainage routes clear. After gardening, check whether soil, mulch or new paving has changed water run-off. Later ground adjustments must not direct rainwater towards the sauna base.
After an extended period without use, inspect the interior, glass, door, lighting and accessible technical components before heating up. Have visible issues clarified before putting the sauna back into operation.
Document the order, foundation and electrical installation clearly
Keep the order confirmation, configuration details, assembly documents and operating instructions together. Photograph cable routes and important foundation details before they are covered. This helps account reliably for concealed installations during later garden work.
Check the delivered version against the order documents immediately. In particular, verify window position, exterior finish and technical equipment. Unclear deviations must be resolved before assembly, as corrections become considerably more involved afterwards.
Record the professionals involved and keep documents for the foundation and electrical work in order. Operating manuals should remain easy for users to find; technical documents belong in a dry, easily located storage place.
Allow for future garden alterations from the outset
If a pool, pergola or further planting is planned later, include the required areas in the first site plan. New elements must not narrow the entrance, direct water to the base or block the chosen view.
During later paving or terrace work, take care not to alter levels and falls around Sana unfavourably. The position of electrical cables and accessible connection points must remain known. Consult existing documentation before excavation work nearby.
Treat Sana as a permanent part of the garden plan. Keep the access route, exterior surfaces and documented cable areas accessible even when making later changes.
FAQ – Bloomcabin Sana
Which window position suits my location?
Choose the rear window if the main view lies opposite the entrance. The side window often works better when positioned parallel to a terrace, pool or house wall. Also check visibility from outside.
Is Sana suitable for couples too?
Yes. Although Sana is designed for four to six people, the cabin also gives couples additional seating space and greater freedom of movement. If you mostly sauna alone, weigh this comfort against the garden space required.
What matters most for the foundation?
With a total weight of around 1,800 kg, the ground must be permanently load-bearing and level. Drainage, unloading and the assembly route should also be considered when planning the foundation.
How does Sana differ from a barrel sauna?
Sana has straight walls made from three-layer, 70 mm CLT panels. This gives it the appearance of a modern rectangular garden building rather than a round sauna made from individual profile boards.
How should I care for the interior thermo-aspen?
Use clean seat pads when sauna bathing and remove damp textiles after use. The interior should then be able to dry completely with ventilation left unobstructed.
How can privacy be improved despite the glazing?
Avoid directing the window towards frequently used paths or seating areas where possible. Planting or fixed garden elements can provide screening, but must not obstruct maintenance access or air circulation.
When should the electrical connection be planned?
Plan the cable route for the 400 V three-phase supply with a REWS-authorised electrical professional before foundation work and assembly. This keeps the intended connection points accessible and avoids later cable routes.
What must be clarified before delivery?
Check the complete route from the unloading point to the foundation, including gates, turns, overhangs and soft surfaces. Also clarify who will handle unloading, temporary storage and assembly.
Is Sana suitable for your planned location?
Key factors are a suitable base, a prepared 400 V connection, a sufficiently clear delivery route and a window position suited to the plot. Also consider drainage, privacy and exterior surfaces that remain accessible.
If you are looking for a barrel form, wood-fired heater or integrated terrace instead of clean-lined CLT architecture, compare further Bloomcabin outdoor saunas.
