FAQs
What Is the Best Type of Sauna Rock?
The best type of rock for a sauna is igneous rocks like Gabro, Olivine, Peridotite, Basalt, Granite, Vulcanite, etc.
What Kind of Rocks Do You Use in a Sauna?
A. In a sauna, you need rocks that are dense enough to retain heat. Igneous rocks (Granite, Vulcanite, Gabbro, Basalt, Peridotite, Olivine, etc) are ideal rocks for a sauna. That said, you should avoid Obsidian and Pumice because they are unable to absorb water and cool off too quickly.
How Long Do Sauna Rocks Last?
The longevity of sauna rocks is determined by the rock quality and how regularly you use the rocks. For instance, if you use them regularly (3-4 times a week), replace the rocks every 4 months. But if you use them once a week, replacing them once a year should be sufficient. As for the quality, choosing good quality rocks is a challenge simply because of the sheer number of below-average rocks available out there. We have compiled a list of the best sauna rocks later in this article.
What Rocks Hold Heat Best?
Igneous rocks (Granite, Gabro, Basalt, Peridotite, Olivine, Vulcanite stone, etc) are the best rocks to use in a sauna. It’s a dense rock with high thermal conductivity which means it’s one of those rocks that hold heat well.
Can Decorative Rocks Be Used in the Sauna?
We don’t recommend using decorative rocks because these rocks are too delicate for regular sauna use. The main purpose of decorative rocks (like white rocks) is to give your sauna a modern look.

Do Round or Split-Faced Stones Produce Better Heat and Steam in the Sauna?
No, neither is better. When you pour water over split-faced stones, it covers a large surface area therefore the steam is robust. In a collection of rounded stones, however, water tends to trickle down quickly as a result the steam produced is softer. So go for split-faced stones, if you want robust steam. But use rounded stones, if you prefer soft steam.
How to Check if Sauna Stones Are Safe?
To check if your sauna stones are safe you need to subject them to the following tests:
- Scratch it with your nails
- Drop it on a hard floor
- Throw it into the fire, heat it thoroughly and then plunge it into the water
If the stone didn’t chip away, break or crack, it’s safe to use.
What’s the Best Way to Arrange Stones on the Stove?
The best way to arrange stones on the stove is to begin by placing the large stones and then use smaller stones to fill in all gaps. The stones will expand and contract so with time you will need to remove old stones and add new ones.
