HUUM HIVE Wood LS 17 Wood-Burning Sauna Stove w/ Firebox Extension | Complete Package Options

Exterior Firebox Loading

The LS firebox extension allows firewood to be loaded from outside the sauna room, making the stove ideal for through-wall installations where you want to keep the bathing space cleaner and more relaxed.

Authentic Wood-Fired Sauna Heat

Live fire creates a traditional sauna atmosphere that electric heaters cannot fully replicate — crackling wood, natural heat, and the ritual of tending the fire.

Large 287 lb Stone Capacity

The HIVE Wood LS 17 holds approximately 130 kg / 287 lbs of sauna stones, helping create softer, more consistent heat and a satisfying löyly experience.

Designed for Larger Sauna Rooms

The HIVE Wood LS 17 is designed for sauna rooms approximately 283–565 cubic feet, making it a strong choice for larger residential saunas, cabin saunas, retreat saunas, and outdoor sauna buildings.

Sculptural HIVE Design

The rounded HIVE form gives the stove a modern Nordic presence while showcasing the natural beauty of the sauna stones.

Tempered Glass Furnace Door

The stainless steel-framed tempered glass door allows you to view the fire, adding warmth and atmosphere to the sauna experience.

Heavy-Duty Flame Tamer

The internal stainless steel flame tamer is approximately 5 mm / 0.2" thick, helping support efficient burning and withstand high temperatures.

Designed and Crafted in Estonia

HUUM sauna stoves are designed, engineered, and precision-crafted in Estonia for an authentic European sauna experience.

What Makes the HIVE Wood LS Different?

Wood-Fired Atmosphere with Through-Wall Loading

The HIVE Wood LS 17 is not simply a standard wood sauna stove. The LS extension changes how the stove integrates into the sauna building.

Instead of loading wood from inside the sauna room, the extended firebox allows the stove to be fired from the adjacent side of the wall. This can make the sauna feel cleaner, more refined, and more intentional, especially in luxury outdoor saunas, cabin saunas, and custom builds where the stove wall is part of the design.

The result is a sauna experience that feels deeply traditional — live fire, real wood, soft steam, and natural heat — while still supporting a more elevated, architectural installation.

Installation Notes

Professional Planning Strongly Recommended

The HUUM HIVE Wood LS 17 should be installed according to the official HUUM installation manual, required safety clearances, chimney manufacturer instructions, and all local building and fire code requirements.

Before ordering or installing, confirm:

• Through-wall firebox placement
  
• Chimney path: through ceiling or through wall

• Combustible clearances
  
• Stone package requirements
  
• Ventilation and air supply
