Frequently asked questions
How is the Modern Shed Sauna different from a plain shed?
It keeps the easy shed frame but adds a steep mono-pitch roof, dark thermowood and a generous glazed tall wall for a contemporary look.
How many people does it seat?
Three to four, set back from the glazed wall.
What heater class does it need?
About 6–8 kW electric, leaning higher for the glazing; confirm with the manufacturer and code.
Does the glazing hurt efficiency?
It raises heat loss modestly and lengthens warm-up a little compared with a solid shed.
Is it hard to build?
It is an intermediate build; the main extra is detailing the large glazing.
