Outdoor Cube Saunas

Outdoor Cube Saunas — Modern, Glass-Fronted

Cube saunas trade the rustic barrel look for a clean architectural form: square frame, full glass front, flat shingled roof, more interior headroom and more usable bench length than a barrel of the same footprint.

Built for daily use rather than weekend novelty: 40mm Thermowood walls hold temperature efficiently, Harvia electric heaters included across the Hekla range, and run cost is typically £1.75–£2.25 per 90-minute session at 30p/kWh.

Range

  • Hekla CUBE 160 — 2 person, 6.8kW Harvia, from £6,799
  • Hekla CUBE 210 — 4 person, 6.8kW Harvia, glass-front
  • Hekla CUBE 250 — 6 person, the full-size cube for shared sessions

Heater upgrade flexibility

Each Hekla cube is listed with a base configuration plus optional Harvia heater upgrade variants — pick the kW that matches your electrical supply at checkout.
