Holl's Utopia 4 — 4-Person Indoor Traditional Steam Sauna

The Utopia 4 is the size most families actually want: four seated — or two of you stretched out flat — behind a wall of glass in a Grade A Canadian hemlock cabin. It's a true Finnish-style steam sauna with a 6kW heater over lava stones, so every session is yours to shape, from dry 90°C heat to soft clouds of löyly.

The starry-sky session

Up to 40 ceiling LEDs in seven colours turn the cabin roof into a slowly shifting night sky — Holl's signature chromotherapy effect. Pair it with the built-in audio (Bluetooth, MP3, radio) from the touch panel and the Utopia stops being equipment and becomes the room everyone argues over.

What's included

• 6kW electric heater with lava stones — included, not an optional extra
• Full sauna kit — bucket, ladle, hygrometer, thermometer, hourglass
• Deep 55cm abachi benches on two levels, cool to the touch at full heat
• 8mm safety-glass door and glazed front panel

Specification

Power and installation

The 6kW heater needs a dedicated hardwired circuit fitted by a qualified electrician. The cabin arrives as a flat-packed precision kit for two-person indoor assembly — no plumbing, ventilation built in to Nordic standards.
