Holl's Moon 4 — 4-Person Circular Infrared Sauna

Seen from above, the Moon 4 explains itself: a 1.8-metre circle with four people sitting around its curve, facing each other. It's the most social shape a sauna can take — no bench hierarchy, no corner seat — wrapped in the same sculptural slatted cylinder as the rest of the Moon range and heated by the largest emitter array Holl's fits to it.

Heat from every point of the circle

Quartz emitters deliver the deep, muscle-level warmth; a ring of carbon panels keeps the ambient heat even wherever you sit. Full-spectrum IR-A, IR-B and IR-C at 40–60°C makes this an easy daily heat — 25–45 minute sessions with no warm-up ritual and no plumbing.

Details

• 7" colour touch screen — the biggest in the Moon range — with chromotherapy and Bluetooth audio
• Two finishes: natural wood or black-on-black with tinted glass
• Session memory for one-touch starts
• Grade A hemlock + abachi, FSC-certified

Specification

Power and installation

At 4.6kW the Moon 4 needs a dedicated hardwired supply installed by a qualified electrician — it is not a plug-in unit. Allow a circle of floor space a little over 1.8m across, plus door swing. Two-person indoor assembly.
