Why the water on the rocks is automated
Pouring water on the rocks is the part of a sauna most people get wrong. Ours does it for you, on a schedule.In a traditional Finnish sauna, someone ladles water onto the hot rocks. The water flashes to steam, the air holds more moisture, and the same air temperature suddenly feels far hotter. That burst is the whole point.
It is also the part that goes wrong. Whoever is sitting closest to the stove decides how often it happens and how much goes on, and nobody else on the benches gets a say. Too little and the air stays dry and flat. Too much and the top bench becomes unusable for the next ten minutes.
What we do instead
Our Finnish saunas dispense the water themselves, on a schedule, alongside controlled air circulation. You do not need to touch anything, and there is no ladle to queue for.
The result is a sauna that holds a consistent heat and humidity for the whole session rather than swinging between the two extremes above. It also means the person who arrived first is not managing the heat on everyone else's behalf.
What it feels like
Expect the heat to build in waves rather than sit flat. When the water hits the rocks the sauna will feel noticeably more intense for a minute or two, then settle. That is working as intended, and it is a reasonable moment to move down a bench if you want less of it.
If a burst arrives and you have had enough, leave. The next round will be there.
