Saunas have been sold in Nepal for years. Working saunas are rarer, because most of what decides whether a sauna performs happens before the heater is chosen: the room volume, the wall build-up, the ventilation path and the electrical supply.
Revival treats a sauna as a system rather than an appliance. We survey the space, size the heater against the real volume, specify the room build, install it, commission it, and keep the parts in Kathmandu so a fault is a callout rather than a season.
What decides a sauna in Nepal
- Supply
- Above 4.5 kW usually needs 3-phase
- Room volume
- Roughly 1 kW per m³, adjusted for glass
- Ventilation
- 5–8 air changes per hour, inlet low
- Wall build-up
- Foil vapour barrier over 60–70 mm insulation
- Lead time
- 6–10 weeks from approved drawing
What actually decides it
- 01
The supply comes first
Most Kathmandu homes can carry 4.5 kW on the existing board. Above that you are into three-phase, and an upgrade often costs more than the heater. We check this at survey, before anything is quoted.
- 02
Humidity is the material problem
Untreated timber will split within two seasons here. Thermally modified aspen and kiln-dried spruce hold up; construction-grade pine does not.
- 03
Service decides year five
Stones crack, elements drift and vents block. All three are cheap to fix and expensive to ignore, which is why every system we supply comes with a Care plan available.
Questions
- How much does a sauna cost in Nepal?
- The cabin and heater are usually about half of a finished residential project. Electrical work and room preparation make up most of the rest, and they vary more between houses than the equipment does — which is why nobody can quote a sauna honestly without seeing the space.
- Can a sauna be installed in an existing house?
- Usually yes. The constraints are ceiling height, the electrical supply and whether the floor can take the load. All three are checked at survey.
- How long does installation take?
- Four to eight weeks from approved drawings for a cabin. Longer where a steam room needs tanking and tiling, because that is wet trades on site rather than assembly.
