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

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.

This catalogue profile is intended for preliminary planning and comparison. Final dimensions, structural design, heater selection, electrical work and safety clearances must be confirmed by qualified professionals and the relevant manufacturer documentation.
