HUUM Stones 24 – High-Quality Olivine Sauna Stones for HUUM Heaters

Optimise Your Sauna’s Heat & Steam Performance

The HUUM Stones 24 are a premium accessory designed for use with HUUM sauna heaters. Each 33 lb (≈ 15 kg) box contains rounded olivine diabase stones sized 2″-4″ (5-10 cm). These stones are selected for their high heat capacity, durability against extreme temperature variations, and for producing a gentler, more even sauna steam thanks to their rounded shape. 
Throwing water on these stones allows heat to radiate both from surface and inner layers, giving a milder “löyly” (steam) experience and enhancing the visual aesthetics of modern HUUM heater designs. 

Key Features & Health Benefits

Key Features:

• Made from premium olivine diabase, known for its high thermal mass and resistance to fracturing. 

• Rounded shape (2″-4″ / 5-10 cm) ideally sized for optimal steam distribution and penetration of water to inner stone layers. 

• Designed specifically for HUUM sauna heaters to complement their aesthetic and functional design. 

• 33 lb box—ideal for maintenance or topping up your heater stone volume.

Health & Wellness Benefits:

• Promotes even heat distribution, reducing hot spots and helping the sauna environment remain more comfortable—supporting better circulation and relaxation.

• The slower, gentler steam produced helps open pores, promote sweating, and support detoxification, while being gentler on the respiratory system compared to harsh bursts of steam.

• By using the correct stones, you maintain optimal heater performance—leading to more consistent sauna sessions which can help with stress relief, muscle recovery, and skin health.
