We host a Bitcoin miner inside a working Finnish smoke sauna on your behalf. The waste heat warms the löyly. The sats stack to your wallet. Once a year, you fly in for the löyly evening yourself.
No payment now. We'll be in touch when seats open.
A simple loop where Bitcoin's waste heat becomes a Finnish luxury.
Your dedicated 4 TH/s ASIC runs 24/7 inside a working wood-fired sauna in Finland. Powered by Nordic hydroelectric energy.
Mining waste heat is ducted directly into the sauna chamber. Real-world utility — no flares, no waste, no apologies.
100% of mined BTC is paid monthly to a Bitcoin address you control. Sauna Hash never custodies your sats. You hold keys.
A private löyly evening at the site, your year's hash report, a glass of Finnish ice wine, and dinner with the founding twelve.
Twelve seats. First-come, first-served. Locked rate for life.
The things people ask before they reserve.
Cheap, clean Nordic hydroelectric power. A climate that's cold ten months of the year, so the heat is genuinely useful — not theatre. And a 2,000-year sauna tradition. Finland is the only place where mining-as-heating actually makes sense as a luxury good.
Your miner sits inside an insulated cabinet ducted directly into the sauna chamber. We control airflow and humidity so the sauna runs at proper löyly temperatures (70–90°C) without overheating the hardware. Surplus heat in summer is diverted to a hot-water loop on site.
You do — through us. Your dedicated 4 TH/s ASIC mines into a major pool, and 100% of the BTC is paid monthly to a Bitcoin address you control. We operate the hardware. You hold the keys. We never custody your sats.
Mined BTC is paid directly to your wallet, so the tax treatment depends on your jurisdiction. We provide an annual hash and payout report you can hand to your accountant. Consult a tax advisor in your country.
48-hour hardware-replacement guarantee. We hold spare ASICs on site. Any downtime is recorded and reflected in your monthly report.
We begin operations once the twelve founding seats are filled. Founding members get first access to the annual sauna evenings starting in the first winter season after launch.
Yes — that's the point. The annual löyly evening is included for every founding member, and additional visits can be arranged at cost. Bring a friend, bring a board, bring a deal worth closing in 90°C.
