How to prepare sauna heater stones before use

Preparing sauna heater stones before use is a fundamental step for every sauna enthusiast. Have you ever considered how much your sauna’s performance depends on something as simple yet impactful as the stones used in the heater?

Stones are more than just accessories. They are the heart of the sauna.

HUUM offers olivine-diabase sauna stones, designed to work perfectly with our elegant and technically sophisticated heaters. Want to get the most out of your sauna experience? It all starts with how you prepare your sauna stones.

Why are sauna stones important?
The importance of sauna stones goes far beyond just heat and steam. They define your sauna’s character – its warmth, atmosphere, and health benefits.
HUUM’s sauna stones are durable and have high heat capacity. We recommend round stones because they produce a gentler steam and complement the heater’s design.
Is it time to make your sauna experience as high-quality as it looks?

Washing sauna stones
The first step is to rinse the stones with water before placing them in the heater. This removes dust and ensures a healthier steam.

Keep in mind when washing stones:

Rinse stones under running water;
Shake or gently brush to remove residues;
Let stones dry completely before placing them in the heater.
A simple rinse guarantees a cleaner and fresher sauna experience.

Correct placement of stones
Correctly placing the stones isn’t just about piling them into the heater. It’s a conscious choice for a better sauna experience.
We recommend always using round and differently sized stones in HUUM heaters. This allows water to move between the stone layers and evaporate gradually instead of bursting all at once from the top layer.
Also, the rounded and smooth shape of the stones beautifully complements our heater design.

Stone sizes:

Stones with a diameter of 3–5 cm;
Stones with a diameter of 5–10 cm.

Tips for arranging stones:

Sort larger and smaller stones separately;
Layer stones in the heater;
Heating elements must not be visible.
“Tempering” Sauna Stones
It is wise to “temper” sauna stones before use to make them more durable.
How to temper stones?
Heat the stones once to a normal sauna temperature, then let them cool down slowly without throwing water on them.

Ready for use
When your HUUM sauna stones are washed, properly arranged, and tempered, they are ready to use. This way, you can experience the perfect sauna every time.

With HUUM’s elegant design and the soft, gentle steam produced by the stones, your sauna will transform from a simple room into a true wellness sanctuary.

How to check the condition of sauna stones?
To check the stones’ condition, remove them all from the heater.
Replace any stones that are cracked or noticeably lightweight;
Clean stones dusty or covered with scale or iron-rich steam residues;
A convenient solution is to replace all the stones at once.
