Design characteristics
Cube massing with one fully glazed elevation and door
Benches angled so the upper tier shares the outlook
Flat roof sloping away from the glass for clean sightlines
Cedar side and rear walls balancing the glazed front
Construction notes
Cedar frame engineered to carry a full sealed tempered-glass front
Insulated opaque walls and warm flat roof offsetting the glazed loss
Careful thermal-break and vapour detailing at the frames
Slab or pier base for the glazing loads with a sealed drained floor
Heating profile
Sized for a 9–11 kW electric heater to offset the glazed front
High stone capacity sustains steam in the glassier room
Expect longer warm-up than a solid-front cube
Ventilation is sized up to manage the glazed wall
Final heater selection must follow the heater manufacturer's sizing instructions, safety clearances and local electrical or fire-code requirements.
Advantages
Panoramic outlook within a crisp cube form
Feels far more open than a solid box
Insulated opaque walls keep it four-season
Strong architectural statement
Limitations
Professional build with structural glazing
High heater demand and slower warm-up
Large glass needs cleaning and condensation control
Higher cost than a solid cube
Common planning mistakes
Over-glazing without upsizing heater and ventilation
Weak thermal breaks causing cold frames and drips
Orienting the glass toward harsh afternoon sun
Under-designing drainage below the glazed front
The cube pushed toward full glazing — a midpoint between the black cube and the
dedicated glass profiles. Figures are reference ranges for planning.
Frequently asked questions
How is the Glass-Front Cube Sauna different from the black cube?
It replaces the black cube's generous window with a fully glazed front face, pushing further toward outlook and away from efficiency.
What heater class does it need?
About 9–11 kW electric to offset the glazed front; confirm with the manufacturer and code.
Is it a professional build?
Yes — the structural glazing and thermal-break detailing require professional work.
How many people does it seat?
Four to six, with benches angled toward the glazed front.
Can it be wood-fired?
This reference configuration is electric to keep the glazed front unobstructed by a chimney.
