The Quattro is the four-sided model in the Cozy Heat range - its name meaning \"four\" - and the most architecturally minimal of all the Cozy designs. Where the base Cozy and OG are trilateral, the O is circular-rimmed, and the SW is cylindrical, the Quattro presents clean, straight four-sided lines with understated elegance. Cozy Heat describes it as stylish and elegant with clean lines and a minimalist design. Its distinguishing feature beyond the four-sided form is the large viewing window - notably larger than the glass doors on the other Cozy models - which makes the dancing flames the focal point of the sauna room from a wide viewing angle. The same 5mm stainless flame cutter, three-stage combustion, and German EN 15821:2010 certification apply identically across the entire Cozy Heat range.\u003c\/p\u003e\n\u003ch4\u003eFour-sided minimalist form and the large viewing window\u003c\/h4\u003e\n\u003cp\u003eThe Quattro body is four-sided with clean, straight lines - a geometry that reads as architecturally precise and modern in the sauna room. Where the three-sided Cozy models have an angular, dynamic quality and the cylindrical SW commands attention through its dramatic rounded form, the Quattro's square or rectangular profile is restrained and quiet - it sits in the sauna room as a functional object of considered minimalist design rather than a statement piece. The large viewing window is what elevates the Quattro above the merely functional: the generous glass panel lets the fire inside be viewed from a wide angle throughout the session, making the dancing flames an integral part of the sauna experience rather than a detail visible only when standing directly in front of the door. Cozy Heat uses the word \"mesmerizing\" to describe the glow of the flames seen through the Quattro's window - and the large format of that window is what justifies it.\u003c\/p\u003e\n\u003ch4\u003eUnderstated elegance - the minimalist Cozy\u003c\/h4\u003e\n\u003cp\u003eThe Quattro is for buyers who approach sauna design the way a Scandinavian architect approaches a building: functional clarity, clean geometry, nothing superfluous. The four-sided body has no curves, no rim elements, no cylindrical drama. Its surfaces are flat and its lines are straight. This is the design language of Nordic minimalism - the same aesthetic that produced the flat-white interiors, clear-finished pine walls, and bare wooden benches of the classic Finnish sauna. In that context, the Quattro is the most authentic expression of the sauna stove as a working object rather than a decorative element. The large glass window is the one concession to visual indulgence - and it is a practical one, since watching the fire is part of the wood-fired sauna ritual that no electric heater can offer.\u003c\/p\u003e\n\u003ch4\u003eComplete package - same proven Cozy Heat engineering\u003c\/h4\u003e\n\u003cp\u003eThe Quattro package includes the stove and sauna stones (style selected at checkout), with the correct stone load pre-specified for each output level: a minimum 265 lbs for the 12kW and a minimum 353 lbs for the 18kW. The flame cutter is 5mm stainless steel. The combustion system is three-stage - primary, secondary, and tertiary air - producing 25-40% less firewood consumption and 73.9% or 81.3% thermal efficiency at 12kW and 18kW respectively. A chimney installation is required and sold separately. All other installation requirements - dry seasoned hardwood, qualified chimney connection, no shared flue - are identical across the Cozy range.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eWood-burning sauna stove package with clean four-sided minimalist design - available in 12kW (210-423 cu ft) and 18kW (317-635 cu ft), select at checkout.
