Rock Your Sauna Experience: The Art of Choosing Sauna Stones

With all the choices you make for your sauna, the rocks that top your heater might seem like a minor detail. But selecting the right rocks for your sauna is crucial to ensure optimal heat and an enjoyable experience. Sauna rocks are placed on the stove to absorb and radiate heat, and their quality and durability significantly impact the performance of your sauna.

With that in mind, here are a few steps to follow when you’re selecting sauna stones:

1. Choose Durable Rocks: The most common and recommended rocks for saunas are volcanic stones, such as peridotite or diabase. These rocks are durable, can withstand high temperatures, and retain heat efficiently. Avoid soft or porous stones, as they can crack or break under intense heat.

2. Mix and Match Sizes: Select rocks of varying sizes, as a mix helps heat distribute more evenly. Larger rocks (about 4-6 inches) work well for the base, while smaller stones (around 2-3 inches) can fill in gaps and allow better airflow. This helps create smooth, consistent heat.

3. Avoid Contaminants: Make sure the rocks are free of chemicals or contaminants that could release harmful gases when heated. Most reputable sauna heater manufacturers sell high-quality stones separately. See our full selection by searching for “stones” on our website!

4. Get the Right Quantity: A typical sauna requires about 50-100 pounds of rocks, depending on the size of the stove and the sauna itself. Check your heater’s manual for the recommended amount.

5. Inspect and Replace: With regular use, you can expect sauna rocks to last two to five years. Inspect regularly to catch damage before it impacts your sauna’s performance. If you notice rocks cracking or developing contamination such as mold, it’s important to replace them.

With the right stones, your sauna will retain and radiate heat effectively, creating the perfect environment for your rejuvenation.
