Hot Buss Cubic Sauna

Where Fire Meets Tranquility

Step into a world shaped by warmth, balance, and elegant design—where every detail is crafted for presence, peace, and purpose. This quadro sauna is more than a structure; it’s a retreat carved from nature, blending sleek modern style with the timeless ritual of heat and silence.

At 4 meters long, this minimalist masterpiece is finished in deep black—an exterior as striking as it is serene. Inside, natural materials breathe life into the space: the soft, dark hues of black alder, the clean grain of spruce, and the solid strength of waxed terrace boards underfoot.

Inside the Heart of the Heat

The sauna room—a spacious 2×2.4 meters—is designed to hold up to eight souls in quiet companionship. U-shaped benches made from black alder wrap around the room, inviting long, lean-back moments of stillness. Each bench is topped with backrests for true comfort, while the black alder continues across the walls and ceiling, cocooning you in warmth and wood.

Let fire bring life to the moment. The powerful 18 m³ wood-burning stove—fueled by wood or briquettes—sits at the heart of the sauna, its firebox cleverly accessible from the outside, keeping the inside pristine. A single tempered glass window, 1.48×1.2 meters, frames the outdoors like a painting—diffusing light into the room and offering a moment of grounding. There’s also a small 30×30 cm openable sauna window, for those who love the whisper of fresh air amidst the heat.

Light is kept simple: a single sauna lamp glows softly from above. Air flows through a ventilation hatch, subtly adjustable for the perfect atmosphere. The flooring—straight terrace boards waxed with oil—guides every step with natural texture. A frosted bronze tempered glass door separates the heat from the calm, and a drainage trap ensures comfort, cleanliness, and ease. Beneath it all, water pipes are ready to connect straight into your home’s foundation.

The Anteroom: A Moment to Breathe

Before the heat, there’s stillness. The anteroom, also 2×2.4 meters, serves as your space to transition, to pause. Whether you’re preparing for the warmth or cooling off in its afterglow, this room is your cocoon.

Equipped with soft ceiling light and one double electrical socket, it offers just enough utility for convenience without disturbing the mood. Fresh air can flow in through its ventilation hatch, and a double-glazed window (0.60×1m) lets in daylight—though it remains non-opening to preserve the structure’s clean lines. The door, PVC and lockable, features optional glazing for a view—or privacy, if preferred.

Just like the sauna, this room is wrapped in planed spruce boards (C24 grade) and grounded in waxed terrace boards. All beneath a bitumen shingle roof with thermal insulation and foil lining, and a strong, insulated chimney with damper and cap.
