Editorial Overview & Architecture Assessment

The SaunaLife Cube-Series Model CL3G brings modern cubic geometry into compact outdoor footprints. Measuring 63" W × 63" D × 84" H, the CL3G replaces traditional curved barrel walls with vertical flat walls, providing 7 feet of interior headroom across every square inch and full-height seating with zero head tilt.

Thermodynamic & Geometric Analysis

The CL3G solves the space limitation of traditional barrels by utilizing soft-corner cube joinery. Bathers on the upper bench sit upright with full head and shoulder clearance, making a 63" square footprint feel like a much larger room.

Signature Design Features

  • Full 7ft vertical wall height provides uncompromised headroom right against the walls
  • Architectural cube shape with curved corner transition staves for structural rigidity
  • Floor-to-ceiling tempered bronze glass front creates an open, modern aesthetic
  • Dual floor drains and black asphalt shingle roof package included

Tested Strengths

  • Straight vertical walls eliminate head-bumping common in compact barrels
  • Fast 30-minute heat-up time with a 6kW or 8kW heater
  • Striking modern architectural aesthetic

Points to Consider Before Purchase

  • Sized for two seated bathers; does not accommodate full flat reclining

Installation, Foundation & Electrical Planning
