- Ventilation is sized up to manage the glazing
Final heater selection must follow the heater manufacturer's sizing instructions, safety clearances and local electrical or fire-code requirements.
Advantages
- Exceptional light and two-sided outlook
- Feels very open in a small footprint
- Insulated solid walls keep it usable in cold
- Strong modern courtyard presence
Limitations
- Professional build with corner structural glazing
- High heat loss and slower warm-up
- Extensive glass needs cleaning and condensation control
- Higher cost than a solid cube
Common planning mistakes
- Under-detailing the glazed corner junction
- Over-glazing without upsizing heater and ventilation
- Placing glazed faces toward overlooking or harsh sun
- Weak thermal breaks causing cold, dripping frames

Frequently asked questions
How is the Glass Cube Garden Sauna different from the glass-front cube?
It glazes two adjoining faces at a corner rather than a single front, for a more open, two-sided room in a smaller footprint.
What heater class does it need?
About 8–10 kW electric to offset two glazed faces; confirm with the manufacturer and code.
Is it a professional build?
Yes — the corner structural glazing and thermal-break detailing require professional work.
How many people does it seat?
Three to four on the two solid walls facing the glass.
Does it suit cold climates?
Yes, with well-insulated solid walls and roof, though it is less efficient and slower to warm than a solid room.
