Hand-built in our workshop, the way saunas are made in Finland. We use teak, pine and red cedar — kiln-dried, food-safe finishes only.
Delivered and installed nationwide. Heater wired, first heat-up with you on-site.
Every Sisu wall is a factory-built sandwich panel. A welded 50 mm box-steel skeleton carries the structure, insulation fills every cavity, a foil vapour barrier seals the hot side, and both faces are boarded with plywood and clad in real wood. Rigid, straight and insulated — built for Thai heat and humidity.
Animated cross-section — the actual construction of every Sisu wall panel.
The same 3D model you configure in the designer is the sauna we hand-build. Drag the handle to compare — or just watch it change.

Good ventilation in your indoor sauna room prevents moisture damage and mould — here's what to do, especially in Thailand's already-humid climate.
Pairing a sauna with an ice bath amplifies the benefits of both — here's the science, the method, and how to get started safely.
Thailand is already hot — so why a sauna? Because outdoor heat and sauna heat are nothing alike, and the benefits go far beyond temperature.
Real electricity cost examples for 3–15 kW sauna heaters at Thai power rates — so you know exactly what to budget before you buy.
Good sauna ventilation doesn't need wall vents or roof holes. Learn how floor gaps and a door gap move fresh air in — and CO₂ out — naturally.
