Product Description
Barrel character with straighter internal walls · Made-to-order outdoor sauna
TimberIN Nordic Square Barrel™: a square-sided sauna offered from two to five metres
A useful middle ground between barrel and cube
The square-barrel section preserves curved roof character but gives the lower room more upright surfaces than a full cylinder. That can make bench placement, back support and internal movement feel more familiar, particularly in longer models. Two-metre versions prioritise efficient heating and a small footprint; five-metre versions support greater occupancy or functional separation at the cost of more volume and site demand. Spruce keeps the structure visually light, while Thermowood deepens the exterior tone. Neither material removes the need for drainage, ventilation and ongoing exterior care.
Rectangular efficiency with documented group progression
Nordic Square Barrel uses a rectilinear 2,340 mm-wide room and 580 mm benches instead of curved barrel walls. That geometry provides full shoulder width and U-shaped social seating. The technical family progresses from 2–4 people/800 kg at 2 metres to 8–10/1,700 kg at 5 metres, all approximately 2,450 mm high before chimney. It is easier to align with a straight terrace, but its assembled width and height demand a substantial delivery route.

| Heaters | M3/M3 SL or 9 kW for smaller rooms; 20 Pro/20 SL or 11 kW-class electric for larger rooms |
The side entrance and U benches define this model’s use
Side entry avoids sacrificing an end wall and supports U-shaped benches for conversation, but requires a clear approach along the long side. The 2–3 metre versions are efficient private rooms. The 4–5 metre versions allow larger groups or a dressing zone; every partition reduces the hot room. M3/M3 SL suit smaller volumes, 20-series wood stoves larger ones; electric 9/11 kW choices require final cubic-volume and supply checks. Spruce versus Thermowood is a finish/maintenance decision after the floor plan is settled.

Square walls do not remove the need for volume matching
The technical sheet recommends heaters by room length, but the final hot-room cubic metres still change with partitions, insulation and glass. A 2-metre U-bench room and a 5-metre divided hospitality sauna should not share a warm-up claim. Use the final drawing and Harvia manual, then commission with intended ventilation. If rapid private use matters, a smaller insulated room is a better answer than a 20-series stove in an oversized shell.
Use the length to improve the room, not merely enlarge it
Compare internal plans and bench dimensions at each length, deciding whether bathers will sit, recline or need a changing threshold. Size the heater for the actual hot room and glazing package, particularly if the longest shell is divided. Prepare a continuous level base, direct water away from the perimeter and confirm delivery turns and overhead clearances. Door and window orientation should protect privacy and make the best use of the garden. Coordinate ventilation, electrical or chimney routes and service access before the order is frozen.
