How to prepare and care for your sauna stones is a foundational practice for every sauna owner. But have you ever wondered how much of your sauna’s performance depends on something as simple—and powerful—as the stones you use?
Whether you’re creating a luxurious home wellness retreat or fine-tuning an existing setup, the stones are more than accessories. They are the heartbeat of your HUUM sauna.
At HUUM, we offer premium-quality sauna stones crafted to work seamlessly with our beautifully engineered heaters. Want to get the most from your sauna sessions? It all starts with how you prepare your stones.
Why Sauna Stones Matter
Why sauna stones matter goes far beyond heat and steam. They define your sauna’s character—its warmth, ambiance, and health benefits.
High-quality stones retain heat efficiently and release steam gently, helping your body relax, detoxify, and even breathe easier. That’s why HUUM uses olivine diabase—a volcanic rock known for its superior thermal capacity and durability.
Why settle for ordinary stones when HUUM offers performance and longevity in one? Isn’t it time your sauna felt as premium as it looks?
Washing the Stones
Washing the stones before their first use is a must-do. Even top-tier stones like HUUM’s may carry dust from manufacturing or shipping—dust that can impair air quality or reduce heater efficiency.
Here’s how to do it right:
-
Rinse under running water;
-
Gently shake or scrub off residue;
-
Let them dry completely before placing them.
A simple rinse today leads to a cleaner, fresher sauna experience tomorrow. Wouldn’t you rather breathe in pure, aromatic steam instead of factory dust?
Placing Stones Correctly
Placing stones correctly isn’t just about loading up your heater—it’s about engineering a better sauna experience.
HUUM’s open-frame heaters pair best with round sauna stones. Why round? Because they not only look stunning, but they allow for better airflow, softer steam, and more consistent heating.
We offer two size options:
-
Small round stones: 3–5 cm, 15 kg box;
-
Large round stones: 5–10 cm, 15 kg box.
Stack like a pro:
-
Larger stones on the bottom for airflow;
-
Smaller stones on top for even steam;
-
Don’t over-pack—air needs room to flow!
Wouldn’t you prefer steam that envelops you gently, without the harsh bursts you get from poorly placed stones?
Tempering the Stones
Tempering the stones is your final step before sauna bliss. Even HUUM’s premium-grade olivine diabase needs to ease into the heat.
Here’s how to temper your stones:
-
Heat your sauna to 65–90°C;
-
Do not add water during this first heat-up;
-
Let the stones bake for about an hour, then cool naturally.
This step protects your stones from thermal shock and boosts their lifespan. After all, wouldn’t you rather enjoy year after year of perfect steam than deal with cracked stones after a few sessions?

A Few Maintenance Tips
A few maintenance tips can help extend the lifespan of your HUUM sauna stones:
- Inspect regularly: Check stones for cracks or crumbling every few months;
- Use clean water: Only pour fresh water on the stones, unless your heater supports aromatherapy.
These practices maintain optimal airflow and heating performance while preserving the clean, modern look of your HUUM sauna.
