Overview

The Narak Medium (4-person) is a 4-person sauna with an external footprint of 2200×2200×2300mm and roughly 3.9 m² of internal bench space. It is one of our indoor builds — made to fit standard ceilings with a flat roof and panoramic glass options.

Construction uses our standard panel system: 12 mm interior cladding over 50 mm rockwool insulation, a sealed vapour barrier, then 12 mm exterior cladding on a kiln-dried frame. The interior is low-conduction thermo-treated timber so the benches stay comfortable at full heat, while the exterior can be specified in pine, teak or red cedar.

It is sized for a 6kW heater. Heaters from 3–9 kW run on a single-phase supply; only larger commercial heaters above 9 kW need three-phase, and the exact wiring is shown in the 3D builder as you design.

Every Narak Medium (4-person) is made to order in Thailand with a 35–50 day lead time from confirmed deposit, and ships nationwide or worldwide as a flat-packed kit with assembly instructions. Open the 3D designer to change the timber, add a full glass front, adjust the benches and watch the price update live before you request a quote.
